The Week in Research Review, etc 7-29-18

/4 Comments/in , , , , , , , , , , /by

Last week was the 1st of my research review that summarized my social media posts from the previous week. It seemed to be well received so I figured I’d continue it. My goal is to help summarize some of the research that I found interesting and package it nicely for my readers.

Each photo contains a link back to a social media feed where you can see the conversation that ensued and maybe chime in…or just be a passive reader and see where the conversation went. You never know where the conversation may go on social media…so be ready! haha!

Socioeconomic Factors for Sports Specialization and Injury in Youth Athletes Jayanthi et al Sports Health Journal 2018.

This study looked at the effect of socioeconomic status (SES) on rates of sports specialization and injury among youth athletes.

They looked at injured athletes between the ages of 7 to 18 years that were recruited from 2 hospital-based sports medicine clinics. They compared these with uninjured athletes presenting for sports physicals at primary care clinics between 2010 and 2013.

They concluded that:
✅High-SES athletes reported more serious overuse injuries than low-SES athletes
✅More hours/wk playing organized sports
✅Higher ratio of weekly hours in organized sports to free play
✅Greater participation in individual sports

I applaud the authors for attempting to bring this very difficult collection of data into a formal research paper. I will say some of the statistics and standard deviations may not make the conclusions as powerful.

I do think this is a good paper to help educate our athletes on injury rates, especially in those that specialize in 1 sport.

From #Twitter’s @retlouping that perfectly sums up what I’ve observed recently on social media with many PT’s.

For some reason, pain science has overtaken most diagnosis and treatment conversations.

It’s as if you get bullied into talking pain science and ignoring our clinical judgment and diagnosis skills. I understand there’s a constant tug-of-war between the biomechanical PT’s and the pain science PTs.

But as usual, the answer usually lies somewhere in between and both groups are correct. The biomechanics of an injury are often important as well as the language we use to explain these tissue biomechanics.

To my fellow clinicians, especially the newer grads and #dptstudent, remember this little cartoon for every future encounter.

Yeah, speak to people in non-threatening tones (in my world it’s just being respectful) but trust me, they WANT to hear what could be going wrong or what may be causing their pain.

Don’t blow off their symptoms and don’t go into depth about pain science because they won’t understand.

Trust me, the clinicians that try to do that often end up losing their patients in the long run.

I hear these stories day after day of people coming to me because the last PT either only talks to them or made them ONLY do strength exercises and it didn’t help their pain.

The PT didn’t listen to them and was so blinded by their pain science background that they ignored the person sitting right in front of them. Remember, the person sitting there will tell you what is going on and what treatment will most help them feel/move better.

Influence of Body Position on Shoulder and Trunk Muscle Activation During Resisted Isometric Shoulder External Rotation Krause et al Sports Health 2018.

The purpose of this study was to examine ER torque and electromyographic (EMG) activation of shoulder and trunk muscles while performing resisted isometric shoulder ER in 3 positions:
✔️Standing
✔️Side-lying
✔️Side plank

Using surface EMG and a hand-held dynamometer, the researchers tried to determine EMG activity of the:
✔️infraspinatus
✔️Posterior Deltoids
✔️Mid traps
✔️Multifidi
✔️External/internal obliques (dominant side)
✔️External/internal obliques (non-dominant side)

EMG values for the infraspinatus were greatest in the side plank position. In general, EMG values for the trunk muscles were also greatest in the side plank position.

✅Their Conclusions: If the purpose of a rehabilitation program is to strengthen the rotator cuff, in particular, the infraspinatus, the side plank is preferred over standing or side lying. If the goal is to simultaneously strengthen both the rotator cuff and trunk muscles, the side plank position again is preferred.

Makes sense but good to see the research and have concrete evidence to back up what we think actually goes on.

Reliability of heel-height measurement for documenting knee extension deficits. Schlegel et al AJSM 2002

Prone heel-height difference of 1cm equates to 1.2 degree difference in knee extension ROM.

Do you use this method to assess knee ROM? I still measure knee extension ROM is supine but find this method helpful as well.

I know my friend and colleague @wilk_kevin has measured this way for many years. i originally saw his use this technique at @ChampionSportsM

I don’t want people to confuse this with prone hangs for knee extension ROM. I am not a fan of that method as I’ve stated in the past.

This is a method to assess knee extension differences, particularly after an ACL reconstruction. I have gone back to using this method for some people that have subtle ROM differences side-to-side.

The patella position (on the plinth or off) did not matter in the study and thigh girth did not appear to make a difference.

I would recommend stabilizing the pelvis to prevent excess ROM from occurring at that region and to better isolate the knee joint.

Have you tried this method? Tag a friend who may benefit from using this ROM method…thanks!

Evidence-Based Best-Practice Guidelines for Preventing #ACL Injuries in Young Female Athletes: A Systematic Review and Meta-analysis Petushek et al AJSM 2018.

Injury prevention neuromuscular training (NMT) programs reduce the risk for anterior cruciate ligament (ACL) injury.

Eighteen studies were included in the meta-analyses, with a total of 27,231 participants, 347 sustaining an ACL injury.

The overall mean training amount was 57 sessions totaling 18.17 hours (roughly 24 minutes per session, 2.5 times per week).

They concluded:

✔️Interventions targeting middle school or high school–aged athletes reduced injury risk to a greater degree than did interventions for college or professional-aged athletes.

✔️Continued exposure to neuromuscular training throughout the sport season seems to enhance prophylactic effects of NMT.

✔️NMT interventions were effective for female basketball, and handball athletes and interventions including various athletes were potentially effective (eg, soccer, basketball, and volleyball).

✔️ Interventions included some form of implementer training (eg, instructional workshop, video, or brochure) on proper program implementation.

✔️Programs including more landing stabilization and lower body strength exercises during each session were most effective.

🤔Programs including balance, core-strengthening, stretching, or agility exercises were no more effective than programs that did not incorporate these components.

✔️ Specifically, programs that included more landing stabilization exercises (eg, drop landings, jump/hop and holds), hamstring strength (eg, Nordic hamstring), lunges, and heel-calf raises reduced the risk for ACL injury to a greater degree than did programs without these exercises.

✅ Wow, lots of great information here. Please share this with a friend or colleague who may benefit from knowing this information.

Hope that helped to catch you up on my posts from this week.

The Week in Research Review, etc 7-22-18

I’m trying out this new concept of publishing my social media posts into a nice package for a weekly delivery to my subscribers.

  1. Knee Case Study
  2. Contralateral ACL Strengthening
  3. Shoulder Static Stabilizers
  4. Weighted Ball Research
  5. Glute Activation


This kid came to me the other day with L knee swelling after sliding headfirst into 2nd base during a baseball game.⠀

Continued to play in the game and even pitched the next day, all without pain or loss of motion.⠀

As you can see from the video, he has a bunch of fluid in his knee, medial ecchymosis (bruising) but full pain-free ROM.

Ligamentous tests appear negative and he has absolutely no pain or stiffness with anything.

I took this video to show what appears to be a bursal sac disruption from the impact of his knee into the ground as he was sliding.

The mechanism fits the presentation and clinical exam.

I advised him to monitor his swelling, wear a knee sleeve and continue his activities per his tolerance.

He is going to touch base with me next week to make sure the fluid is dissipating (and not worsening) and he remains asymptomatic.

What do you think? Am I missing anything? What’s your diagnosis? Tag a friend who may be interested in this case.

Cross-education improves quadriceps strength recovery after ACL reconstruction: a randomized controlled trial. Harput et al Knee Surg Sports Traumatol Arthrosc. 2018

This study looked at a group of ACL reconstructed patients that were divided into 3 groups.

All 3 groups performed the same standardized ACL rehab, but one group was the control group that performed the standardized rehab only.

The other 2 groups did either 3x per week extra concentric knee extensions on their uninjured leg for 2 months (beginning at 1-month post-op through 3-months post-op) or additional eccentric knee extensions on their uninjured leg 3x per week for 2 months between months 1-3 post-op.
💪🏼
They found that the quads strength for the concentric group was 28% greater compared to the control group. 💪🏼
The eccentric group was 31% greater when compared to the control group.

Conclusion: Concentric and eccentric quadriceps strengthening of healthy limbs in early phases of ACL rehabilitation improved post-surgical quadriceps strength recovery of the reconstructed limb.

Pretty crazy stuff and one more reason to work on bilateral strengthening with most of our patients, especially when they’re post-op ACL reconstruction.

Do you work on bilateral strengthening? if not, why? If you do, what other studies have you seen that show similar results?
Tag a friend who may benefit from this study or let’s discuss in the comments section!

This picture shows a simplified view of the static stabilizers of the shoulder joint. I highly recommend reading a classic paper by Wilk et al 1997 JOSPT that talks about this and cites a paper from Bowen et al Clin Sports Med 1991 @wilk_kevin

When one is picturing these stabilizers, the superior glenohumeral ligament (SGHL) is most taut when the shoulder is externally rotated at 0 degrees of abduction.

As we progress to 45 degrees of GH abduction, we stress the middle glenohumeral ligament (MGHL) as we externally rotate the humerus.

Finally, at 90 degrees of GH abduction, we stress the inferior glenohumeral ligament (IGHL) as we externally rotate. More specifically, the anterior band of the IGHL.

As we internally rotate at 90 degrees of abduction, we stress the posterior band of the IGHL.

These concepts have rehab implications and should be kept in mind when we’re rehabbing people after an injury or surgery.

For example, if someone has an anterior Bankart lesion (front labral repair), then we need to progress them slowly into external rotation, especially at 45 and 90 degrees of abduction.

Another example would be a rotator cuff repair, like the supraspinatus. We would want to progress them slowly at lower degrees of abduction 0-45 degrees but maybe we can progress them a bit quicker at 90 degrees of abduction.

Hope these concepts make sense because they are very important to understand for many patients with shoulder injuries.

Effect of a 6-Week Weighted Baseball Throwing Program on Pitch Velocity, Pitching Arm Biomechanics, Passive Range of Motion, and Injury Rates. Reinold et al Sports Health Jul-Aug 2018. @mikereinold⠀

Our 1st of potentially 3 research articles looking at the effects of weighted balls on youth baseball pitchers.

High school baseball pitchers performed a 6-week weighted ball training program.

Players gradually ramped up over the 6 weeks to include kneeling, rocker, and run-and-gun throws with balls ranging from 2oz to 32 oz.

🤔After 6 weeks, the weighted ball group did increase velocity by 3.3%, 8% showed no change, and 12% demonstrated a decrease in pitch velocity. Also of note, 67% of the control group also showed an increase in pitch velocity.⠀

The weighted ball group had a 24% injury rate although half of the injuries occurred during the study, and the other half occurred the next season. There were no injuries observed in the control group during the study period or in the following season.

The weighted ball group showed almost a 5-degree increase in passive shoulder external rotation, also known biomechanically as the late cocking position or layback position.

There were no statistically significant differences between pre- and post-testing valgus stress or angular velocity in either group.

✅Our conclusion: Although weighted-ball training may increase pitch velocity, caution is warranted because of the notable increase in injuries and physical changes observed in this cohort.

Tag a friend looking for a glute🍑 killer!⠀
Hip prep is a series of 6 exercises I’ve adopted from my girlfriend @smenzz and her clinic @eliteorthosport. I use it with my patients to prime the glutes and lower body in general before getting into more dynamic and plyometric activities. I will make the statement right now: if done RIGHT, it’s an absolute glute killer & I promise you that you will feel your glutes!⠀
.⠀
I like these 6 exercises in particular for a variety of reasons.⠀
✅They challenge the glutes in all 3 planes of motion.⠀
✅They hit all types of muscle contractions: isometric, concentric, and eccentric⠀
✅They are performed upright in a functional position⠀
✅There is a variety of double leg, single leg, and split stance variations⠀
✅They train proper lower extremity alignment in a variety of hip and trunk flexed/neutral/extended positions⠀
.⠀
The 6 exercises are:⠀
1️⃣3 way clams: 5 per leg per position⠀
2️⃣Side steps: Alternating steps to the left and right starting with 1 step all the way to 5 steps⠀
3️⃣Monster Walks: 10 steps forward, 10 steps backwards⠀
4️⃣W’s: 10 steps to the left, 10 steps to the right⠀
5️⃣Squats: 10 squats⠀
6️⃣Single leg fire hydrants: 30s per side⠀
.⠀
💡Understand that you first need to teach these exercises in isolation first, before throwing someone all 6 at once⠀
.⠀
Have fun!⠀

Hope this helps you keep up to date and fulfill my goal of this website…simplify the literature and bring great content to you so you can apply it 1st thing Monday morning! Happy Reading! 👊🏼

Quadriceps Stretching after Knee Surgery: A tweak to the technique

/4 Comments/in , , , , /by

Obtaining full knee flexion after a knee surgery or knee injury can be difficult for some. The transition from passive knee flexion in seated (my preferred) or supine (not preferred!) can be a challenge for the physical therapist, once they are starting to work on quadriceps stretching. This blog post serves to help modify the prone quadriceps stretching technique after a knee surgery. The goal is to better localize the stretch to the muscle and not cause further pain and discomfort to the patient.

In the past, I’ve talked about restoring knee extension after surgery, particularly after an ACL reconstruction. If you missed that blog post, you can read it here here and here. You might say I have a slight obsession with talking about ROM after surgeries.

For a common surgery like an ACL reconstruction, I often see people present to me without full ROM. That’s why I continue to discuss techniques that can help other clinicians and patients restore their ROM before it’s too late.

Why is full ROM important after knee surgery?

Well, we think there’s a pretty close link between long-term issues and not restoring knee ROM.

In Shelbourne’s article in AJSM 2012, he states that “abnormal knee flexion at early follow-up, abnormal knee extension at final follow-up, abnormal knee flexion at final follow-up, partial medial meniscectomy, and articular cartilage damage were significant factors related to the presence of osteoarthritis on radiographs.”

He also went on to say that you had a 2x increased risk of knee arthritis if you don’t get full ROM. This was similar to having had a meniscectomy surgery or articular cartilage loss.

For such a simple concept, we PT’s can really affect the long-term outcomes for our patients if we don’t get full knee ROM. So why are people still struggling years after their knee surgery? I don’t know… but it’s troubling and definitely avoidable in most patients.

Check out this study from the Journal of Athletic Training in 2015. They discuss how a patient’s flexion ROM can help significantly improve their IKDC scores (functional score) during the 1st 2 months post-op.

Simple Modification to Prone Quadriceps Stretching

I began to think about this topic when I was reading a Facebook post in one of the PT groups and it made me think. We always talk about knee extension and there is some research that discusses the importance of safely obtaining knee extension ROM. I put this study in a recent Instagram post and got some pretty good response.

It seems that whenever I talk about knee ROM after a surgery, people’s ears perk up. Let’s go to the video and talk about a simple technique I use to improve knee flexion ROM after a surgery or injury.

As you can see, a small tweak to your technique can really make a big difference. Again, I’m not sure what exactly is going on. It seems like I’m adjusting the position of the tibia just slightly and that is influencing the location of the stretch toward the quads. If I take my hand away, then they feel the pain and pressure in the front of the knee and it does not feel good.

Slow and Steady Knee Flexion

For the record, I’m not one of those PT’s that likes to be super aggressive and push my patients to tears. I’ve inherited those patients from other PT’s and that technique often fails.

When I talk about improving prone knee flexion, I’m talking about improving quadriceps flexibility and length. Remember, if you have someone lie on their stomach and you try to flex their knee, you’re either limited by pain, joint capsule or the rectus femoris (2-joint muscle.)

It’s not until I think the knee has reached a period of calm that I begin pushing into prone flexion. I’m not using this to crank and get 5 more degrees for my documentation. I’m using this at an appropriate time to improve muscle flexibility and maybe get that end range of motion that is so important.

Remember, obtaining full knee ROM is a process, but a very important process. it’s not going to happen quickly, especially if you’re wicked aggressive (my Boston comes out when I get fired up!!)

Try it for yourself

So this week, try this technique out on one of your clients who may be struggling with regaining their knee flexion ROM. I’m curious to know what you think and if it works for you. As we’ve seen, it’s very important to get that full ROM back after a surgery and this is one modification that I think can help you immediately.

Loss of extension after ACL surgery: How to assess for a cyclops lesion

/30 Comments/in , , , , , /by

Loss of extension after an ACL reconstruction can be debilitating for the patient. It’s not as common as you would think but I see it enough in the clinic from people that are months out from surgery. Usually, this loss of knee extension after an ACL reconstruction is caused by a cyclops lesion. Let’s dive deeper into this!

Often times, they’ll present with anterior knee pain, posterior knee soreness and a relatively weakened quadriceps muscle that just won’t return. No matter what they do to get the motion back, the knee just never feels normal.

I’ve written about the loss of extension after an ACL reconstruction in the past. In this post, I discussed how I like to work on knee extension immediately after an ACL surgery. There are a few ways that I think are most effective and with minimal patient efforts.

What is a Cyclops Lesion?

For those not familiar, a cyclops lesion is a wad of scar tissue in the anterior aspect of the knee joint. It is believed to be a remnant of the previous ACL stump that had remained during the reconstruction surgery. At least that’s one theory. Another theory states that it may be fibrocartilage as a result of drilling the tibial tunnels.

Whatever the case, this arthrofibrosis (scar tissue) physically blocks the knee joint from locking out into full extension. Check out this MRI that shows the scar tissue in the anterior knee.

Cyclops lesion in the anterior knee blocking full (hyper) extension

How do I assess for a cyclops lesion after ACL surgery?

In this video, I describe why and how I assess for a cyclops lesion. Check it out.

Is it a Cyclops lesion or just a tight knee?

From the video, you can clearly note that anterior pain, in my experiences, is most often related to a cyclops lesion. Other factors to consider include:

  1. temporary/transient gains in extension
  2. anterior knee pain after increasing activity
  3. poor patella mobility
  4. quads just won’t come back
  5. continued hamstring/calf soreness

These are tell-tale signs that there’s more going on and you should refer back to the doctor so they can order an MRI to rule in/out the anterior scarring. If diagnosed, the best (and only) option is to have a knee scope and remove that scar tissue.

There’s nothing else that can be done. No PT, injections or manual therapy can restore full symmetrical knee extension.

The scar tissue needs to be removed by surgical excision. Aggressive PT should commence immediately after surgery to restore the extension range of motion.

The Best and Easiest Way to Restore Knee Extension after an ACL

Rehab after an ACL is never easy. There are many things that could affect a patient’s outcome. I’ve treated hundreds of patients after an ACL reconstruction and each one is a unique challenge. I wrote about this in a previous post here..check it out and let me know what you think.

I put this video together for Mike Reinold’s website so you could see what I exactly do to gain knee extension back….and why I’m not a fan of prone hangs. Hope it helps with some of your knee patients.

Final Cyclops Thoughts

As a PT or athletic trainer, don’t blame yourself if the patient needs another surgery to remove the scarring. It seems as if it was inevitable and was going to occur no matter the efforts to work on knee extension. I think the lesson here is:

  • work on extension early and often
  • maintain good compliance at home
  • assess/measure each visit to determine gains or losses
  • early patella mobility and knee PROM
  • get the pain and swelling out as quickly as possible
  • refer back to the doctor if the ROM not improving despite your best efforts

Hope this post helps you get better outcomes for your ACL patients!

Anterior Knee Pain- A Test for Fat Pad Irritation

/9 Comments/in , , , , /by

We as physical therapists are constantly seeing patients with anterior knee pain with a very vague history. Often times, there’s not a specific onset or mechanism of injury. With that, it seems as if the retro patellar fat pad is a common source of pain in many people and is commonly overlooked.

What actually hurts in the knee?

Whenever I am evaluating someone with knee pain, I always keep in mind the Dye et al AJSM article from 1998. In my opinion, this is a keeper for all PT’s and future PT’s to have in their arsenal of top literature papers.

For those that are not familiar, let me explain it a bit.

Basically, San Francisco orthopaedic surgeon Dr. Scott Dye had his knee scoped without any anesthesia. That’s right, classic beast mode!

He did have local anesthesia (for the record), so they could make the incisions…otherwise, he was awake and alert for the whole procedure.

This allowed him to report back to his colleagues (one being his brother) an actual pain response as they were poking away at the different structures within the knee. He ranked the pain on a 0-4 scale with 0 being pain-free (patella cartilage) and 4 being a severe pain (fat pad, anterior synovium, joint capsule.)

You can read the article to get the full gist (and I HIGHLY RECOMMEND this!) but my point is to let you realize that there are only certain structures capable of causing severe pain in the anterior knee.

Their Findings

Cartilage is avascular and aneural. It has no blood supply or nerves that innervate it. None! So the whole chondromalacia patella diagnosis attempting to implicate a maltracking patella is often hogwash.

But the fat pad, anterior synovium, and anterior capsule are extremely painful and are often involved, I believe, in patients that we see on a daily basis.

In my opinion, this is a diagnosis that sees us more than we see it. Like thoracic outlet syndrome… we can talk about that a different day though.

Back to the point of the blog.

1 Test for Fat Pad Assessment

Assessing the knee and asking the right questions is critical. Besides a tremendously great subjective, there’s one test that I use to rule in or out a fat pad irritation. Check out the video below:

I promise you this test is a great way to establish a pretty clear diagnosis and reassure the patient that a specific structure may be the issue.

When it’s painful, its pretty obvious and the patient can immediately report back to you their symptoms. I test for this a bunch in a given week and it’s not always present. But when someone presents with a positive finding, it’s pretty relieving to them (believe it or not.)

Differential Diagnosis

Keep in mind, my differential diagnosis is all over the place at times.  With knee pain you need to consider:

  1. Meniscus (see my previous blog post)
  2. ITB
  3. Osteochondral lesion
  4. Patella tendonitis
  5. Pes anserine bursitis
  6. MPFL sprain
  7. Hamstring strain
  8. Plica syndrome
  9. MCL/LCL
  10. Tumor

That’s a bunch to consider for someone who can’t really explain why or when their injury occurred. That’s why I still believe this overuse injury sees us more than we see it.

Treatment of Fat Pad Irritation

This one can get a bit tricky. Again, it’s often due to an overuse injury. In others, it’s attributed to kneeling on it for too long or banging it against something. In those more acute cases, the answer is pretty straightforward. Ice, motion and progressive return to their function.

In the overuse group, which is more prevalent in my opinion, we need to figure out which stimulus is causing the issue. It’s often due to starting a new program or ramping up too quickly during some training event.

In these people, I need to modify their volume of training or destress the area by giving them new activities that they can do pain-free…but only for a short period of time.

Along with activity modification, a course of some form of modality (yup, the M-word was used) can help expedite the pain control. I still have a special place in my heart for iontophoresis with dexamethasone. I’ve had tremendous results in patients with fat pad irritation.

I also like to use a low-level laser to help with the healing process (future blog post alert!) I’ve used it on my self for various ailments and even my dog after her ACL surgery. I’m definitely a believer in the healing power of the laser when applied in the correct situation.

Besides all of that, I would also want to assess the person’s movements and attempt to adjust any motions or movements that I thought could contribute to the knee pain. Often times, there’s an underlying weakness or misconception of a weakness that needs to be explained to the patient.

These things run their course for a few weeks but should improve pretty quickly if handled correctly. Patient gratification is pretty obvious because their pain diminishes after a session or 2 and they buy into the program pretty quickly.

Fat Pad Conclusions

Infrapatellar fat pad irritation can be functionally debilitating. I believe it presents itself pretty often in the clinic, more than most PT’s realize. Use my test above to see if it truly is a fat pad issue. Here’s a nice open-access article that you can read to learn more about the fat pad.

Remember, the test should be pretty obvious and locally oriented. If pain-free, then move on. If not, then try some of my above recommendations. It’s usually an overuse issue so you need to adjust their volumes and maybe some form of mechanics.

Diagnosing meniscus tears: What’s the literature telling us now?

/9 Comments/in , , , , /by

Meniscal tears are commonly observed in an outpatient physical therapy setting. The ability of a PT to evaluate a patient’s knee and diagnose a meniscus tear can help guide the treatment plan for that patient. Having specific tests that can accurately and quickly pick up a meniscal tear are valuable.

Lots of test options but stick with the subjective

There are many theories, tests, and exam techniques that are reported in the literature. I definitely don’t know all of them but have been exposed to a bunch of common ones that I have found to be helpful.

Before I get bogged down with these tests and try to sound intelligent, I’d be remiss to not state the obvious… the subjective portion of the exam is by far the most important aspect and needs to be thoroughly utilized.  In many cases, ok maybe most cases, the client will tell you what’s going on…as long as you ask the questions correctly and listen to their responses.

This will most likely be a blog post at some point in the near future but as a collective profession known as medicine, we suck at listening and utilizing the information correctly. But I digress…

What Tests are out there?

There are many tests reported in the literature, commonly including:

  • McMurray’s
  • Apley’s compression
  • Joint line tenderness
  • Thessaly’s
  • End range flexion/extension overpressure

Unfortunately, the literature does not support using these tests to diagnose and may add to the fear avoidance a patient may exhibit after such a diagnosis. This systematic review and meta-analysis in the British Medical Journal stated:

“The results of this systematic review indicate that the accuracy of McMurray’s, Apley’s, JLT and Thessaly to diagnose meniscal tears remains poor. This conclusion must be taken with caution since frequent methodological design flaws exist within the included studies, most studies suffered from various biases, and between-study heterogeneity makes pooled data unreliable.”

To tell you the truth, I don’t even do the Apley’s compression test. I probably haven’t done the test since PT school sometime in 2001. Never saw a value, kinda like the Thessaly Test. Nice in theory but just not good enough when tried in a clinical setting. Unfortunately, most research and the associated methods are lacking so the results are pretty poor when trying to diagnose a meniscus tear.

Oh boy, now what do we do? Do we even need to diagnose the tear in the 1st place and add more fear to the patient’s hurting knee?

Even need to Diagnose Meniscus Tears?

I say yes… but with a caveat!

We must accurately diagnose and explain to the patient that many people have meniscal tears in their knee. The recent literature builds a strong case for a very good recovery without surgery. That’s right, surgery is often not needed for many people diagnosed with a meniscus tear.

This landmark paper in the New England Journal of Medicine (neighbors of Champion PT and Performance in Waltham, MA) really created waves when it was released in 2013. They stated that “outcomes after arthroscopic partial meniscectomy were no better than those after a sham surgical procedure.” Now, these people did have a diagnosis of knee arthritis as well, but so do many of the people we see on a daily basis.

Hopefully, many clinicians have changed their treatment algorithms and have opted for conservative treatment first.

Don’t get me wrong, surgery may be needed, especially for the people sustaining an acute meniscus tear.  But that may only be a small portion of the people presenting to us in the clinic.  In these people, I still say give it a bout of conservative treatment to calm the knee down, restore ROM and strength and see how they do. Maybe a 6 week PT course is all they need, you never know. I have definitely seen it work, no doubt!

What meniscus tests do I do?

With all of that being said, I still believe your clinical examination is ultra-important to help guide the treatment plan.

As usual, keep it simple and don’t over-search. It needs to be pretty straightforward and it often is. The exam NEEDS to match the clinical history…let me say that again….the exam NEEDS to match the clinical history.

The client is going to tell me their issue and I just need to make sure my tests and measures solidify my working theory. I promise you that if you ask the right questions the right way, then you will have that much more information to at your disposal.

So, my go-to tests are:

  1. Joint line palpation
  2. End range flexion/extension pain/locking
  3. McMurray’s (but often not very valuable)

…in that order. I’d say joint line palpation and end range of motion are my 2 most valuable tests. I still do the McMurray’s test to see if it can add to the story. It often gives me very little information so I don’t rely on it too much.

Many of you are going to ask why I didn’t even mention the Thessaly test. I see it talked about a lot on social media. I just don’t understand why we’d want to put our client in a weight-bearing position, slightly bend their knee, and have them twist on a painful knee.

Never mind the research telling us that the test is not very valid which goes completely against early research that said it was a valid test.

The more (tests) the Merrier

Maybe we need to combine this test with others to help improve our accuracy as this paper showed in 2009.

Either way, there seems to be a case to cluster tests to help us draw better conclusions, as was stated in this paper in 2006.  “Five positive findings on composite examination yielded a positive predictive value of 92.3%. Positive predictive values remained greater than 75% with composite scores of at least 3 in the absence of ACL and DJD pathologies.”

This paper nearly matches my thought process. Obtain a good history, assess the joint line for tenderness, then put the joint at end range flexion/extension. If the symptoms match, then we will OFTEN have a meniscus tear.

Keep in mind that the particular side of the meniscus tear may influence the ability to detect a pathology. Lateral meniscal tears may be easier to distinguish than medial meniscal tears if we’re talking about joint line tenderness alone and was even the case in this 2009 article too.

Final Word on Diagnosing Meniscus Tears

Meniscus tears are pretty prevalent in the outpatient setting. Rehab specialists, including PT’s and athletic trainers need to understand what tests are best to deploy. I’m sticking with my in-depth history, joint line tenderness, and painful end-range as my go-to cluster of tests.

I’m pretty sure it has done me well over the years…and the research seems to match my thoughts too.

The Challenges of ACL Rehab- It’s Never Easy!

/7 Comments/in , , /by

It seems like I always have someone on my schedule that is post-op ACL reconstruction (or anything post-op, for that matter!). Although I thoroughly enjoy progressing ACL rehab because this population is very motivated to get back to their sport or activity.

Knowing that it scares the bejeezus out of me at times!

There are so many variables, almost too numerous to count, that can affect the outcomes. Some are modifiable and some are not. I wanted to take a moment and step back from the boring “just need to get knee hyperextension posts” that I’ve done in the past and take a more holistic approach.

The Little Details

For those that know me, this may be a bit of a stretch. But I honestly think that the little details of the process are just as important as the big picture. It’s like anything else, you need to focus on the little details in order for the final goal to be achieved.  The same is true for ACL rehab but I feel like this is something that is missed by many and can make or break a good outcome (which we know can be hard to find).

There’s a reason why nearly 25% of ACL reconstruction patients have a retear event and need a revision surgery. I’m not saying this is the only reason but I will say the mental aspect of the process can help the athlete during he process, and that begins post-op day 1 when they present to me in the clinic!

So, what’s going through my mind when I’m rehabbing someone after an ACL reconstruction?

via GIPHY

Human Soul, Mind, Spirit

From the get go, I’m trying to figure out the psyche of the person in front of me. Look up the word psyche in the dictionary and it means ‘human soul, mind or spirit’. This exactly sums up what I’m trying to define early on.

The tricky part is connecting with this person (and their family) so they can gain the utmost trust in you. You see, their future is in your hands so there’s a lot of blind trust that is going on early in the rehab process. They’re in pain, clueless to the process and hoping you know what the heck you’re doing.

I know the basic principles of ACL rehabilitation- calm the knee down, get their ROM back and get them walking/running/jumping. There’s a lot more to do but I’m being wicked brief, I know. And it does go way beyond that, trust me! It’s much easier said than done for most.

Some Factors to Consider

Each case involves a gazillion variable to consider when I’m trying to outline a logical rehab program. Often it can consist of:

  • pre-op status
  • graft choice
  • meniscal involvement
  • other joint issues (bone bruise)
  • revision surgery
  • surgeon
  • pain status
  • previous surgery (if so, how did that go?)
  • ultimate goal
  • school status
  • home situation
  • good support
  • insurance (not as much for me due to OON)

It goes on and on, trust me! If you don’t believe me, then read this paper that I found AFTER writing this blog post. Basically sums up my nearly 15 years of experiences very well. Check it out, if you want… Psychological predictors of anterior cruciate ligament reconstruction outcomes: a systematic review.

So my mind races as I’m trying to figure this stuff out. I’m also trying to sound half educated as I progress their program and observe their response to each new exercise, cue and bad joke I make.

Some people freak out with anyone touching their knee cap while others just sit there and chat it up. If I see the freaked out person begin to squirm, I need to anticipate that the next few steps may equally be a challenge for the client. Knowing that (and assuming that), I go into show mode and make every attempt to turn the focus from their knee and each and every painful bend or leg raise, to something very obscure. To me, it’s all about mind games.

Mind Games

Wait, I’m playing mind games with my clients? You better believe it. This is basically how I test my clients’ response to me, my personality, my rehab style and how the next 6-9 months will go. If I see a stoic, scared response, then I need to step up my game and find a common connection, QUICKLY!

The rehab especially at the beginning, is not about their flexion ROM or their swelling control but it’s about them gaining trust in me as their PT. Do they want to come to PT and put their complete future in my hands? Do they trust that I know what I’m doing and can lead them to their eventual goals? I hope so and it starts from that 1st joke I make or that 1st outcome study that I have to quote.

I don’t know which one will win them over but I have to be ready to offer either (or both). The last thing I need to happen is to have them show up for the next session and completely lose faith. If for some reason their swelling is up or their pain is worse (which happens in nearly 100% of the cases that I see) then I need to be able to talk them off the ledge and let them understand that it’s completely normal.

N=1 mindset

They have no comparisons to make. They also think their experience is worse than all others and that no one else has had swelling 2 weeks out of surgery. Or that all people can walk without crutches 7 days out of surgery, but they still have their crutches 14 days out. They have an n=1 mind and have no other experiences to compare it to but I have a database of cases to rummage through in my head.

Hope my mind can come up with a similar situation, make it real for them and get them back to reality…and get their faith back!

Trust me, no surgery is a guaranteed success and we know ACL surgery is a long ways a way from being perfect but we can truly make a difference by our confidence and personality.

I’ve made a career of this and can’t stress it enough!

2 Tips to Improve Your Post-op Rehabilitation Outcomes

/2 Comments/in , , , , /by

I’ve treated hundreds, if not thousands of postoperative patients in my career. I’m always surprised to hear from others how they progress their patients. When I first got into physical therapy, I was all about protocols. I didn’t have much experience.

I would literally follow it word for word and do my best to match the person to that little piece of paper. Little did I know that I was gravely mistaking! This post will hopefully improve your post-op rehabilitation outcomes.

As I became more comfortable, let’s say 1-2 years in, I got cocky and progressed people based off of their presentation. I almost wanted to show off to THEM that they were doing better than the protocol. This made them want to go faster through the process and all was good…kinda.

Wake up call

Then I began to see people get sore, stiff and regress. So much for being the guru of post-op rehabilitation. I had to reassess my approach.

Fortunately, we had a steady flow of post-op patients at our disposal in Birmingham, AL.  Each day, week and month I would get 1, 2 3, 4 new post-op patients a day. I would look for the protocol and fight the temptation to progress too quickly.

Trial and Error

Through experience and chatting with Kevin Wilk (and Mike until he left for the Red Sox in 2005), I began to take a more conservative approach, especially during the 1st 6 weeks after surgery. I realized the protocols were intentionally broken down into phases of rehab for a reason.

Those initial weeks after surgery are all about calming the joint down. Whether it is a knee replacement, an ACL or a rotator cuff repair, they all cause pain and swelling. We truly need to address each circumstance on a case-by-case basis.

There are always the outliers, and you know who they are. The guy that walks in with no crutches 1 day out of surgery and says “I’m here for PT, let’s do this”.

Then you have the guy who gets rolled into PT with a wheelchair and can’t do anything because he’s puking, constipated and cranky. Completely different approaches to rehab for these 2 folks.

The cocky guys need to be held back a bit because you know he’s going to keep pushing it and make his knee swollen. The guy in a ton of pain needs reassurance that you will take good care of him. You just need him to be a big part of the process and get over his fear.  You’re almost playing mind games on a daily basis and need to adjust to each individual’s personalities.

Regression to the Mean

The majority of people present somewhere in the middle- can function but in some pain. They know they need to do the PT and you know they need more pain meds, quickly!!

They’ll unwillingly participate in the early process because the doc said so but often not like you for it. Then they’ll thank you later on when they’re moving well and feeling great!

So with that, what 2 things do I think people need to consider when rehabbing a post-op patient?

via GIPHY

The 2 most important factors to progress a post-op patient

  1. Don’t overdo it- less is more
  2. End feel assessment

Don’t Over Do It- Less is More

As tempting as it is to progress someone quickly through the rehab process, fight the temptation in the early phase of PT. That 1st 4-6 weeks after surgery are critical to regaining homeostasis in the joint.

Dr. Scott Dye talks about this perspective in regards to patients that have patellofemoral pain or anterior knee pain: The pathophysiology of patellofemoral pain: a tissue homeostasis perspective. His research has really shaped how I treat and progress people.

The quicker you can get the joint to ‘calm down’, the better they’ll be able to progress. I utilize range of motion and some modalities such as ice. I can’t overstate it enough that we can make or break an outcome in the first 4-6 weeks.

There’s no need to crank on someone’s knee because the protocol says you must have a certain ROM by a certain time. I’ve found great success with simple passive range of motion seated at the edge of the table at least 2x each visit.

It’s a lot more of a comfortable position for the patient than the dreaded prone ROM. Keep in mind, this puts a stretch through the quadriceps. It becomes an extra barrier that you must get through in order to achieve your motion goals. Plus, the patient feels like a WWE wrestler and may reflexively tighten up in anticipation of pain.

Each patient would get 5-10 minutes of PROM at the beginning and end of each session. No matter how busy I was or how many people were staring at me ‘waiting for their ‘next exercise, they all got 2 ROM sessions.

They looked forward to the range of motion and patiently watched me go from table to table (this was back a couple years ago) knowing they were next up.

This hands-on interaction is very important to develop the PT-patient relationship. This will hopefully blossom in the coming weeks and months as the patient progresses through the process.

I wrote about this previously for our Champion PT blog and I’m sticking to it Power of Touch. I truly believe that this is often missing and a huge complaint from people who end up coming to Champion PT in pursuit of reclaiming their functional goals.

End-feel Assessment

In my opinion, end feel is the single most important aspect of rehab progression a therapist needs to consider.  Being able to assess end-feel may be one of those skills that come with experience.

If a post-op rotator cuff is having painful guarding, then the therapist must adjust the process. Maybe it’s the frequency of the HEP, or the actual HEP content, or the patient’s pain control. There are so many factors to consider but the fun part is adjusting and reassessing. It’s a constant game of give and take!!

Commonly, the PT has to dive deeper into the patient’s life to figure out why this end-feel has changed. Often times a past medical history of diabetes can cause increased stiffness.

Also, you’ll find that they stop taking their pain meds because ‘they make me feel funny’ or ‘I have to drive to PT, don’t I?’ Everyone’s response to a surgery is different and it is very important to understand what could affect a patient’s presentation, as complicated as it may seem.

Ultimately, the goal is to get a nice capsular-like end-feel that has the potential to slowly stretch out as you progress the intensity of the ROM.

Assess and adjust each visit

I usually have them increase the frequency of their home exercises or adjust the daily frequency to easy bouts of motion 3-4 times per day. Most people think doing it 1x per day (if you’re lucky) is all they need so they can get credit for doing their ‘homework.’

I’m not afraid to lay the guilt-trip on them and remind them that their outcomes will only be as good as the effort they put into their rehab.  This usually gets the point across and we can progress on with the rehab process. This will allow us to quickly gain back the ROM and usually make that end-point not so hard or painful.

Conversely, a Bankart repair in a young athlete should be progressed at a slow speed so the tissue is not ‘stretched’ out. This often results in a nice, capsular endpoint. Should they begin to feel tight, don’t panic! Young adults, say up to 25-30 years old, very rarely get too tight.

Let the process happen, progress appropriately. The excessive ROM gains may cause the patient to have further issues down the road if their instability returns.

Take Home Point…

As much as we think we know about rehab progression after surgery, the only true feedback is from the patient.  Listen to them, monitor their response to the rehab and you will be well on your way to getting superb outcomes.
