ACL tears and bone bruises

/0 Comments/in , , , , , , , , /by

Research Review

Not sure if you saw my recent post on social media about bone bruises after an ACL tear so I wanted to discuss it further here.

In this study, the authors looked at the incidence of radiographic chondral changes (without correlation with clinical and functional outcomes) on MRI 5 years after the ACL tear.

Bone bruises often coincide with an acute ACL tear and can be seen on an MRI. Basically, a larger bone bruise was shown to have a significant influence on chondral changes 5 years post-surgery.

In most of the cases, the lateral side of the knee (both the tibia and the femur) were involved. Whereas the medial side had fewer incidences of a bone bruise after the injury.

This is very typical after an ACL injury and previously cited by numerous authors.

I’ve always said that these bone bruises need to be communicated throughout the rehab team. These bone bruises should influence the progression back to sport.

Delay impact activities after ACL surgery

It is for this reason that I have delayed most of my athletes’ return to impact activities until 4-5 months after the surgery. I often don’t initiate running and plyometrics until 4-5 months after the surgery.

We need to respect the bone bruise healing times (which are still not truly known). They seem to take months to achieve homeostasis, which means no pain or swelling.

Only another MRI would truly confirm full healing so we need to rely on symptoms, most of the time.

I think this may allow the athlete to achieve better long-term success. But we need to understand these bruises more before we can fully determine the correct rehab process.

I think the long term life of the athlete’s knee can be influenced by our rate of rehab progressions. To me, slower seems to be better in these situations.

Gone are the days of trying to return our athletes back to their sport as quickly as possible.

Take the time to get their motion back, especially knee extension.

We are beginning to better understand the implications of these bone bruises on the long-term health of the athlete’s knee.

Educate the patient fully and build confidence! Rehab after an ACL surgery is never easy so don’t take anything for granted!

The Week in Research Review, etc 12-10-18

This week we’re still playing with formats and learning these Instagram changes. With that, in the week in research review 12-10-18, we discussed many topics that I wanted to share!

Surgery vs Physical Therapy for Carpal Tunnel Syndrome

Cost-Effectiveness Evaluation of Manual Physical Therapy Versus Surgery for Carpal Tunnel Syndrome: Evidence From a Randomized Clinical Trial Fernández-de-las-Peñas et al JOSPT 2018.

This Level 1b study looked to evaluate cost-effectiveness differences of manual physical therapy versus surgery in women with carpal tunnel syndrome (CTS).

Performed in Spain, 120 women with a clinical and electromyographic diagnosis of CTS were randomized through concealed allocation to either manual physical therapy or surgery.

They concluded that manual PT including desensitization maneuvers of the central nervous system has found to be equally effective but less costly, i.e., more cost-effective than surgery for women with CTS.

From a cost-benefit perspective, the proposed manual PT intervention of CTS can be considered.

Interesting results but 2 obvious limitations to this study:
1️⃣No control group. What if the symptoms could spontaneously improve over time
2️⃣ They only looked at 1-year improvement and not short-term improvements. I would’ve liked to have seen 3 months and 6 months results as well to see the acute effects.

Not sure what to make of this study but it does seem as if a population of Spanish women may respond to Rx of CTS without surgical intervention.

This could be a huge cost/time saver for society!

Return to Sport Criteria and Reinjury Rates

The Association Between Passing Return-to-Sport Criteria and Second ACL Injury Risk: A Systematic Review With Meta-Analysis  Losciale et al JOSPT 2018.

Not going to lie, this study caught my attention because the results match my confirmation bias.⠀

I’ve been saying for years that hop tests, even combined with other tests, just don’t cut it.⠀

I wrote a blog post about this too for @mikereinold. This study, although with its limitations, did show that passing RTS criteria did not show a statistically significant association with risk of a second ACL injury. 

This review also determined that 12% of those who failed RTS testing suffered a graft injury, compared to 5.9% of patients who passed. 

It seems as if quadriceps strength measured via isokinetic testing or isometric testing may be an important factor to consider for RTS decision making.


Also, hamstring-quadriceps strength ratio symmetry should also be considered.

So with this review demonstrating that current objective criteria-based RTS decisions did not show an association with the risk of a second ACLI, how does this affect your practice?

Physical Therapy vs Knee Scope for Meniscus Tears

💥PT vs Scope for Meniscus Tear 💥
.
Effect of Early Surgery vs Physical Therapy on Knee Function Among Patients With Non-obstructive Meniscal Tears: The ESCAPE Randomized Clinical Trial. van de Graaf VA et al JAMA Oct. 2018

Among patients with non-obstructive meniscal tears, PT was equal to arthroscopy for improving patient-reported knee function over a 24-month follow-up period. 

They went on to say that “Based on these results, PT may be considered an alternative to surgery for patients with non-obstructive meniscal tears.”

So basically, if there’s no bucket handle tear present that may be blocking joint range of motion, then it is highly encouraged that the patient #GetPT1st and not do surgery.

Without going out on a limb, I’d say this is a much more cheaper treatment option as well and would save society many costs associated with the surgery and lost time from work.

I do note a couple limitations: the surgical group did not get PT after surgery if they did ‘as expected’ but they could get PT to help improve their symptoms.

The PT group did pretty basic exercises although leg press, lunges, and balance type exercises were included.

Have you read this paper? It was a multi-center, randomized controlled trial performed in 9 hospitals in the Netherlands.

So, are we encouraged or surprised? Let me know by commenting below…thanks!

Shoulder Health Accessory Exercises

by @kieferlammi

Want strong and healthy shoulders!?

Shoulder strength is about more than pushing big lifts like strict pressing, push pressing, etc.

If you want a robust, healthy, well moving shoulder you should be including lower level drills that more specifically address scapular and RTC strength and control. –

I will always be a fan of traditional exercises like side like ERs, Prone Ys, Ts, etc.

Lately, I’ve thrown in more band work because it’s easy for me to do for higher volumes on a frequent basis and I enjoy the constant tension that the band provides. 

Give these two exercises a try:

✅ Band Front Raise Pull-Apart

✅ Band Overhead Y Raise

I find that these two do a great job of targeting my mid back and posterior shoulder without much compensation through a big range of motion.

Give them a try either in a warm-up for 1-3 sets of 10-15 reps or at the end of a training session for 2-4 sets of 10-25 reps depending on the difficulty of your band and your capacity.

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.

Online Knee Seminar Course

We discuss this and much much more in my online knee course that I have with Mike Reinold. If interested, check it out at www.onlinekneeseminar.com and let me know what you think. We cover the anatomy, rehab prescription, ACL, knee replacements and patellofemoral issues both non-operative treatment and post-operative treatment. This is an awesome course if you’re interested in learning more about rehabilitating the knee joint.
