The Week in Research Review, etc 11-26-18

This week, I discussed the progression of someone after a knee surgery. I tried to highlight the key stages and some techniques that I like to use to advance the patient’s mobility and comfort. Take a look at The Week in Research Review, etc 11-26-18 and share with your friends. Hope it helps you improve your patient care tomorrow and beyond!

 

ACL Reconstruction in a Pediatric and Adolescent Population

1st Day of #PT after an ACL Surgery

Patella Mobilization after Knee Surgery

Knee Flexion PROM after Surgery- Seated or Supine?

Stretching the Quads after Knee Surgery

Assessing for a Cyclops Lesion after an ACL

Assessing for Fat Pad Irritation of the Knee


 

 

ACL Reconstruction in a Pediatric and Adolescent Population

17 Year Follow-up After Meniscal Repair With Concomitant ACL Reconstruction in a Pediatric and Adolescent Population. Tagliero et al AJSM 2018

Results: 28% failed meniscal repair and required repeat surgery at the time of final follow-up. They also showed that outcomes and failures rates were comparable across tear complexity.

Guess that means that no matter the tear type, there was no difference in outcomes or retear rates. Although the repair techniques are now outdated and no longer used.

Their study also showed a 30% failure rate for meniscal tear repaired in the medial compartment at index surgery and 7% in the lateral compartment.

Interesting long-term outcomes that may help to guide your rehab and client advancement (and prognosis). Keep these in mind when you treat a future adolescent or pediatric ACL patient.


 

 

💥1st Day of #PT after an ACL Surgery 💥

If you have never treated a post-op ACL, then this video should interest you!

This is what the knee looks like that 1st day after surgery and can often set the stage for what’s to come over the next 6-12 months.

Often, the patient is both very curious and ultra-grossed out by the 1st unveiling. It can be stressful for them to see their knee in this condition so you really have to confidently reassure them that it is very normal.

The blood-soaked gauze is mainly saline that was used to irrigate the knee during the reconstruction. Some still leaks out of the incisions the 1st few days and can often be confused with true blood.

Understand that this is quite normal and happens to most every ACL patient’s knee that I’ve seen…nothing to worry about!

From here, I’d work on patella mobility (see the post later today) and then work on flexion ROM at the end of the table.

Again, it’s very important to get the knee moving after surgery. This will help with pain, swelling and gain confidence that the rehab process is moving forward.


 

Patella Mobilization after Knee Surgery

Get the patella moving early with #patella mobilizations immediately after surgery. One major reason (amongst many others) why we need to get our clients into #PT early.

I am certainly a very loud advocate for early PT and getting the patella moving can help to prevent excessive scarring, which can affect ROM and quadriceps force output.

Glove up and get that patella moving in all directions… medial, lateral, superior, inferior!


 

 

🤔Knee Flexion PROM after Surgery- Seated or Supine? 🤔

I’ve treated many patients after an ACL I can honestly say that this may be a huge influence on the early ROM outcomes that you may see.

I’ve tried to bend the knee in both supine or seated, as the video shows, and there’s no doubt that most people tolerate the seated version so much better after a knee surgery. In particular, a big surgery like an ACL, TKA or MPFL reconstruction.

It just seems to be more comfortable and with less stress on the anterior knee because of the position of the tibia (at least I think so!).

My theory, it seems as if the supine position may cause a slight posterior sag which may cause more pain and guarding than when they’re seated at the edge of the table.

I use a similar concept later on in the rehab process when I’m initiating my prone quad stretching. You can see a definitive improvement when I wedge my hand in the popliteal fossa and create a slight anterior translation on the tibia.

Most people say that the anterior knee pain that they were feeling (and not a quad stretch) was replaced by a stretch feeling only and no more anterior knee pain.

Try it out with your ACL patients and see what position they like best…I’ll bet I can covert you over if you still bend your knee patients in supine!


 

💥Stretching the Quads after Knee Surgery 💥

Continuing my sequence of videos after a knee surgery, I discussed my technique for progressing knee flexion PROM once they hit 120 degrees or so of flexion.

At this point, they’ve probably maxed out how much ROM they can achieve at the edge of the table. They’re ready to get that end range of motion and even some quadriceps flexibility.

In prone, most people will often feel a pain or pressure in the front of their knee when you try to bend it.

To overcome this, I like to wedge my hand into the back of the knee and give an anteriorly directed force through the gastrocnemius (calf) soft tissue and into the tibia.

This seems to create just enough movement of the tibia on the femur to take the pressure off the front of the knee. This may redirect the forces more onto the quadriceps muscle.

You’ll need to play with the amount and direction of force but most often they’ll begin to feel a better quad stretch.

Try this technique out on your next knee surgery client and see if it helps them. I usually initiate this ~4 weeks after an ACL but timeframes will vary person to person.⠀


 

💥Assessing for a Cyclops Lesion after an ACL 💥

In this video snippet from my YouTube Channel, I discuss how to assess for a Cyclops lesion in a knee. In particular, after knee surgery.

A patient with a potential cyclops lesion, they often present with loss of normal knee extension compared to the other side. They’ll often have anterior knee pain and poor patella mobility. Sometimes a tight feeling in their hamstrings and calves, too.

No matter how they try to regain their extension ROM, the knee just never feels right. Often times, surgical intervention is needed to remove that scar tissue.

Immediate rehab should continue to work on knee extension ROM using low load long duration stretching and aggressive patella mob’s.

No one’s to blame if this occurs. We don’t know exactly why it occurs in some people but we believe a remnant of the ACL stump may be a source of the frustrating issue.


 

💥Assessing for Fat Pad Irritation of the Knee 💥

Anterior knee pain is very common in the outpatient #PhysicalTherapy setting.

One of my go-to tests to assess for fat pad irritation is simply trying to capture the fatty tissue in the anterior aspect of the knee joint during active and/or passive ROM.

In this snippet from my YouTube channel, you can see that I pinch the fat pads on either side of the patella tendon as @corrine_evelyn is actively extending her knee. I’ll also do it in a relaxed state to assess passive irritability.

I 1st learned this test from @wilk_kevin and it continues to be a mainstay in my knee examination algorithm.

As for a treatment, it usually comes down to a volume issue and/or strength issue or both.

I’ll usually have to address the volume of the activity by relatively easing off of the activity while simultaneously adding in exercises to address an underlying weakness.

Remember the Dye et al study in AJSM 1998 when he talked about the fat pads being super painful during his arthroscopic surgery without anesthesia. Makes sense why they can be so painful if the knee stresses fall upon this tissue.

We talk about this study, fat pad irritability and much much more in our online knee seminar course.

The Week in Research Review, etc 11-19-18

Great ‘Week in Research Review, etc 11-19-18’ that I hope you find helpful to your practice.

I’ve always touted the importance of the subjective portion of the exam so I wanted to share a slide from a recent talk I gave to a group in Canandaigua, NY. Obviously, the squat is a fundamental movement and I wanted to give some basic positions that I use to help assess. So excited that I’ve launched a brand new Medbridge course that helps the rehab specialist better eval and treat the baseball pitcher. On my YouTube channel, I discussed my thoughts on setting the scapula with various upper and lower body exercises. And finally, my co-worker Kiefer Lammi discusses the landmine with exercise.

 

Importance of the Subjective Exam

Assessing the Squat

My New Baseball Medbridge Course

Set the Scapula with Shoulder Exercises?

6 Ways to use the Landmine by @kieferlammi


 

💥Subjective the most important aspect of the Evaluation💥

This slide, taken from this past weekend’s course in Canandaigua, NY is always a favorite of mine.

I try to keep a slide like this in all of my lectures because I have found that this portion of the examination can give the rehab specialist a huge look into what is going on with the person in front of them.

Don’t get me wrong, I still consider the biomechanical aspect of what may be causing their symptoms.

It often comes down to a tissue capacity issue but it’s up to me to determine the appropriate course of treatment.

These questions will help build confidence in your client and guide the early stages of rehab.

Do you have any specific questions that you like to ask your clients during their 1st few sessions? Remember, these questions are just not for the evaluation. You should be asking these questions periodically to gauge progress and help guide the next phases of rehab, too!


 

🔅Assessing the Squat 🔅

Squatting is a fundamental movement that all of us have to do on a daily basis.

Utilizing several different positions can help the rehab specialist better assess the squat and develop a treatment plan that enables their client the ability to improve their squat pattern.

In the above videos, I have utilized 3 different squat patterns and will outline them by the degree of difficulty.

✅The Overhead Squat- by far the most challenging version which challenges the shoulders, thoracic spine, lumbar spine, pelvis, knee and ankles.

A movement limitation at any of these joints will most likely cause the squat pattern to break down. Using overhead resistance would further challenge the system and potentially cause the squat to further breakdown.

✅Arms Crossed Chest Squat- alters the challenge by taking most of the shoulder and thoracic spine out of the equation and isolates the motions to the lumbar spine, hips, knees and ankles.

I often use this position as my fundamental motion because most people don’t have to squat with any weights over their head. This position, in my opinion, should be the most informational and utilized.

✅Counter-weight Squat

This position changes the center of mass by moving some of the weight distribution more anteriorly (front) and making the squat motion slightly easier. I use this position as a regression, for some, which allows them to squat with less stress and potential difficulty.

There are many other variations to the squat that you can make but I wanted to highlight a few of the major changes that you cause successfully. Assessing the squat is essential and can give the rehab specialist a nice picture of the function of multiple joints during a common movement.

💥Should you Set the Scapula with your Shoulder Exercise?💥

In this video excerpt from my YouTube channel, I wanted to discuss my opinion on setting the scapula during common exercises.

I think there’s an obvious role for setting the scapula during a heavier lower body lift like a deadlift.

But for a classic upper body exercise like the Full Can (Scaption Raises) or prone T (horizontal abduction), prone Y (Prone full can), etc then I definitely want the scapula to freely move along the rib cage.

I did a quick literature search and didn’t see anything obvious that helped to guide my thoughts so most of this is anecdotal. Check out the video and comment below.

Do you coach your clients to set their scapulae before a rotator cuff workout? If so, why? If not, do you think we should reconsider?


 

6 WAYS TO USE THE LANDMINE!⁣

Great post from our own @kieferlammi at @championptp on various ways to use the landmine in your client’s workout routine.

If you don’t have one, then I’d highly recommend you try to obtain one because they are highly versatile and can be used in many stages of rehab. See Kiefer’s original post below 👏🏼

_____________

6 WAYS TO USE THE LANDMINE!⁣

The landmine attachment is a super versatile tool for loading that is traditionally known for being used for angled pressing variations. While that’s probably my most programmed use for it, it also provides benefit to a ton of other movements by placing the load and direction of force at a bit of an angle, which can help to promote a particular path of movement, like sitting back more in a squat or lunge. Here are 6 of my favorite ways to use the landmine:⁣

1️⃣1-Leg RDL⁣

2️⃣Split Stance Row⁣

3️⃣Reverse Lunge⁣

4️⃣Deadlift⁣

5️⃣Squat⁣

6️⃣Russian Twist⁣⠀

The Week in Research Review, etc 11-12-18

This week in research review for 11-12-18 we focused a bit more on assessment and also dabbled in some basic treatment strategies for the back and shoulder. Check out the topics below and like them or comment on Instagram to keep the conversation going…thanks all!

 

  • A quick fix for a sore low back?
  • Knee Fat Pad Testing and Diagnosis
  • How to Assess the Elbow for a Tommy John (UCL) Sprain

Looking for a quick fix for a sore low back?

I’m speaking from personal experiences when I post a few of the common exercises that have helped me tremendously in the past.

I’m not saying that this is all you have to do but I do think that new onset of low back soreness, you know that tightness that you feel on either side of your spine, can be somewhat alleviated with some foam rolling and active range of motion.

I would definitely include more focal strengthening of the core like deadbugs and bird dogs, squats, deadlifts (when they’re ready), etc.

But for the purpose of this post, I think some foam rolling and motion to the area can take the edge off of someone’s soreness and get them feeling a little better. That’s my goal for many and hopefully those small gins can add up to big gains in the long run!

Do you utilize these techniques as well? If you don’t, then I suggest that you try! They’ve helped me numerous times and continue to help me when my soreness gets a bit out of control.

Tag a friend who may want to check out this post…thanks!

Thanks @corrine_evelyn for the demos!


 

Knee Fat Pad Testing and Diagnosis

Here’s an excerpt from a previous blog post where I talked about anterior knee pain fat pad irritation. Link in bio!

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

Meniscus (see my previous blog post)⠀

ITB

Osteochondral lesion

Patella tendonitis

Pes anserine bursitis

MPFL sprain

Hamstring strain

Plica syndrome

MCL/LCL

Tumor

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 this test to see if it truly is a fat pad issue.


 

How to Assess the Elbow for a Tommy John (UCL) Sprain

In this excerpt from my YouTube channel, I discuss the tests that I use to help identify an elbow sprain, typically seen in the baseball players that I treat.

In the full video, I discuss:

✅Joint Palpation

✅Seated Milking Sign

✅Prone Valgus Test (maybe a new one for you!)

✅Supine end range External Rotation with Valgus Extension Overload (VEO)

I also wrote a blog post about this topic so hopefully you’ll go to my site and read a bit more about this.

If you treat baseball players of all ages, then you should know how to diagnose a UCL sprain.


 

The influence of lumbopelvic control on shoulder and elbow kinetics in elite baseball pitchers

Laudner et al JSES 2018.

This study looked at 43 asymptomatic, #NCAA Division I and professional minor league baseball pitchers. They measured the bilateral amount of anterior-posterior lumbopelvic tilt during a single-leg stance trunk stability test.

The Level Belt Pro (Perfect Practice, Columbus, OH, USA) was used to assess anterior-posterior lumbopelvic control. The LevelBelt Pro consists of an iPod–based digital level secured to a belt using hook-and-loop fasteners.

This test has been used and studied previously by Chaudhari et al (JSCR 2011) and he showed that pitchers with less lumbopelvic control produced more walks and hits per inning than those with more control.

Also, pitchers with less lumbopelvic control have been shown to have an increased likelihood of spending more days on the disabled list than those with more control (Chaudhari et al AJSM 2014).

“The results of our study show that as lumbopelvic control of the drive leg decreases, shoulder horizontal abduction torque and elbow valgus torque increase.”

Have you tried this simple test? I will say that having the ability to detect millimeters of motion is clinically difficult.

It is good to see such a simple test utilized clinically can help aid in determining the need for more core/hip exercises for our pitchers. In all, I think it’s a safe bet to incorporate these exercises in all pitchers’ programs.


 

Full Can or Empty Can?

– by @mikereinold 

Great Post by @mikereinold on which motion is BEST to isolate the supraspinatus during arm elevation. I know you can’t isolate the supraspinatus but numerous studies have (Kelly et al 1996, Reinold et al 2004) shown that the full can (or thumb up position) is better than the empty can position.

Check it out below! 👇🏼

Full Can or Empty Can? – by @mikereinold⠀⠀
-⠀⠀
🧠 WANT TO LEARN MORE FROM ME? Head to my website MikeReinold.com, link in bio.⠀⠀
-⠀⠀
I’m still surprised after all these years that I still see the empty can exercise kicking around. I analyzed these two movements many years ago in an article in JOSPT and showed that the full can exercise (thumbs up 👍) had similar EMG of the supraspinatus with lower levels of deltoid EMG, while the empty can (thumbs down 👎) had higher levels of deltoid EMG.

Why does this matter?

Well, think about it. If you are performing this exercise you probably are trying to strengthen the rotator cuff. And if you are weak and performing an exercise with more deltoid, the ratio of cuff to deltoid will be lower and you’ll have more potential for superior humeral head migration.

Plus, let’s be honest, the empty can just hurts… It’s also a provocative test, and I don’t like to use provocative tests as exercises. 😂😂😂⠀


 

The Week in Research Review, etc 11-5-18

The Week in Research Review, etc 11-5-18 was filled with more informative and eye-opening posts! Lots of visually stimulating posts to help clarify what exactly is going on in the hip joint with PROM. Another post that shows the suction effect from an intact hip labrum… amongst other great posts.  Just some great stuff..hope you enjoy!

 

  1. Manual Forearm Resistance Drills
  2. ACL Graft Healing Times to Maturation
  3. Hip Capsule Stress with PROM External Rotation
  4. Muscle Activation Affected by Hip Thrust Variation
  5. Hip Thrust Form by Bret Contreras
  6. Hip Joint Suction Affected by labral Status

 

 


Manual Resistance Forearm Exercises

In this post, I wanted to show you guys some of the manual resistance drills we use @championptp on our shoulder and elbow clients, especially our baseball players. We love to use these drills because we can control so many variables with each athlete and tailor it for their specific needs.

We can control the speed and tempo, the direction of forces (eccentric, concentric), and the magnitude of the forces. Plus it’s a great way to interact with our clients. It’s also a great way to feel how well they’re progressing in their programs instead of just giving them dumbbells.

I have found these manual resistance drills to be very helpful with my overhead athletes and hope you give them a try on your clients soon! Let me know what you think or tag a friend below who may like to use these drills too.

In my course that I teach around the US, I try to include these concepts so you can practice and be able to utilize these drills for your clients…thanks!


 

ACL Graft Harvesting and Healing times

In this post, I wanted to show some research studies on graft healing times and why we need to respect tissue biology.

The systematic review from AJSM 2011 looked at ‘The ‘‘Ligamentization’’ Process in Anterior Cruciate Ligament Reconstruction.’

They essentially looked at 4 different biopsy studies on BPTB and Hamstring autograft reconstructions. They concluded that maturation of the graft, as determined by mainly vascularity and cellularity, was not complete until 12 months at the earliest. The healing time even extended to 24+ months as well.

The ligamentization endpoint is defined as the time point from which no further changes are witnessed in the remodeled grafts. The surgical procedure is quite involved, as you can see in the video that I took from @drlylecain on #YouTube.

As I’m rehabbing my clients, my decision making and post-op progressions often take into account:

✔️Healing biology

✔️Graft harvesting

✔️Graft Type

✔️Bone bruise presence (often!)

✔️Other concomitant issues (meniscus, articular cartilage).

So, respect the tissue and allow natural healing to occur before you add more exercises or are concerned that they’re not making the gains you’d expect.⠀


 

 

Hip Capsular Closure: A Biomechanical Analysis of Failure Torque

Chahla et al AJSM 2016

Interesting look at tissue failure, albeit in a cadaver graft, that should help to guide the physical therapist or ATC early in the rehab process after a hip scope.

The purpose of this study was to determine the failure torques of 1-, 2-, and 3-suture constructs for hip capsular closure to resist external rotation and extension.

The 3-suture construct withstood a significantly higher torque (91.7 Nm) than the 1-suture construct (67.4 Nm) but no significant difference was found between the 2- and 3- suture construct.

The hip external rotation degree in which the capsule failed was:

✅1-suture construct: 34 degrees

✅2-suture construct: 44.3 degrees

✅3-sutures: 30.3 degrees (yes, smaller than 2-suture construct)

I think as a #PT, we need to keep this study in mind and respect the healing tissues after a hip scope.

Love when we can get this information and put it into practice, similar to RTC repairs, ACL, etc.

Obviously, this was on a cadaver where there’s no guarding, pain or muscle contraction. We still need to know that there MAY be enough tension on the capsule to create potential issues (like tissue failure).

If you treat patients after hip scopes, then I recommend you read this cadaveric study.


 

 

Barbell Hip Thrust Variations Affect Muscle Activation

COLLAZO GARCIA et al JSCR 2018

This study looked at the EMG activity of various lower body muscles while performing the hip thrust in various positions.

Their results showed that by varying the foot position into more external rotation, you can recruit the glute max and medius more than by the traditional hip thrust.⠀ …”the activity of the gluteus maximus increases significantly reaching up to 90% MVIC with only 40% of 1RM” with this hip ER variation.

Also, ‘when the distance between the feet is increased, the activity of knee flexors increases. Therefore, this is a very recommendable option to increase hamstring: quadriceps co-activation ratio.’

I like this study because it helps guide our rehab if we’re targeting a specific muscle group a bit more because of an injury or surgery.

It’s one of my go exercises for anyone with a lower body injury, especially after an ACL reconstruction. But I do use this exercise for most of my clients rehabbing from any injury, including the upper body.

It’s a great way to recruit the gluteus maximus and medius, which we know are hugely? (is that a word?) important to help produce and dissipate forces during athletic movements.

The exercise was widely researched by @bretcontreras1 and should be a staple in your rehab programs.

Check it out and add this to your go-to exercise list…thanks!


 

Hip Thrust Form

[REPOST] and a great one from @bretcontreras1 talking hip thrust form, which is perfectly coinciding with my post earlier today on variations to the hip thrust and how they affect muscle activation. Check out his original post below…highly recommended!

Teaching optimal hip thrust form is complicated. While the occasional lifter prefers and functions better staying fairly neutral in the head, neck, and spine, the vast majority of lifters do best maintaining a forward head position, which leads to ribs down and a posterior pelvic tilt.

It’s not just the forward eye gaze; the whole head has to maintain its forward position. You’re not hinging around the bench; the body mass above the bench stays relatively put, while the body mass below the bench is where the movement occurs.

The astute science geeks out there will rightfully point out that posterior pelvic tilt is associated with some lumbar flexion, and that lumbar flexion under load can be problematic. However, lumbar flexion is only dangerous when the discs are simultaneously subjected to compressive forces. With this style of hip thrust, the glutes are driving hip extension and posterior pelvic tilt, and erector spinae activation is greatly diminished. Core activation is what creates the bulk of the compressive forces, so with the erectors more “silenced,” the discs aren’t as compressed. This makes the exercise very safe. In fact, it’s safer than the “neutral” technique because as you rep to failure or go a bit too heavy, you will inevitably arch the chest and hyperextend the spine, which can lead to lower back pain. ⁣

We have 200 members at Glute Lab hip thrusting day in and day out, and there have been zero injuries to date. Considering how heavy we go, this is astounding.⠀

Hip Joint Suction and Stability

[REPOST] From @chicagosportsdoc and a very cool look at the suction within the hip joint that contributes to its stability. As the video progresses, they have simulated a labral tear that shows how easily the joint can dislocate. Once the labrum is repaired, the suction effect is recreated, and joint stability is re-established.

That’s 2 posts this week on the hip…if you want to see some awesome posts, then follow him. He just got on Instagram but his visual posts really aid in learning the mechanics of the various joints…see below!

An impressive demonstration of the powerful hip suction seal. When the hip labrum is injured, the seal is disrupted which can potentially produce microinstability. A labral reconstruction can restore the suction seal #labrum #sportsmedicine #hip #anatomy#orthopedicsurgery #medicine
