A missed peroneal tendon injury: Is this the cause of inappropriate surgery and continued foot and ankle pain?

Ross A. Hauser, MD., Danielle R. Steilen-Matias, MMS, PA-C.

Peroneal tendon injury

If you are reading this article, it is likely that you have become an expert in peroneal tendon injury because you have tried many treatments and you are still researching why you still have pain and swelling on the outside of your foot, leg, and ankle. For many patients who reach out to us, their injury started with a rolled over to the inside ankle or degenerative wear and tear problem that one day finally popped.

Over time you may have become expert in things that were not helping you. Specifically the RICE protocol of Resting, Icing, Compression (ankle braces and ace bandages to support ankle instability), Elevation. You also know that acetaminophen (Tylenol), ibuprofen (Advil, Motrin), are only helping so much and you are worried that continued use of Nonsteroidal anti-inflammatory medicines (NSAIDs) will not only not help your situation but lead to side-effects.

This article will focus on the lead-up and post-surgical problems some patients may experience with peroneal tendon surgery and problems of peroneal tendinopathy.

Many people do very well with surgery, they are in a walking boot after 2 weeks, into physical therapy soon after, and for the most part, complete a successful recovery and are happy with their surgical outcomes. These are not the patients we see in our office. We see the people who had the surgery, the surgery was not as successful as everyone hoped. Post-surgical symptoms can range from general ankle and foot instability to consistent pain, tightness, and loss of mobility. This article is for those people.

“My problem is I have developed scar tissue”

The emails that are sent to us from people looking for options post-surgery go something like this:

I am about 10 months out after surgery. I had an injury, high ankle sprain. It was not responsive to conservative care treatments so I had the surgery. I still cannot bear full weight on my foot and I still have a lot of pain and swelling. I am also starting to get some numbness that I did not have before. I am being told that I may have scar tissue developing and this may need to be surgically removed.

Or like this:

I am about four months post-surgery and I have been told that I have developed scar tissue. It is causing a lot of pain. I have been walking around with a boot for months. Now I don’t know if I will be able to get this boot off. I cannot walk without it. I started physical therapy 2 months after the surgery, I have been going since and there has been no improvement. Now I am being told I MUST have a second surgery.

So why not get the second surgery? Concerns over the lack of the second surgery’s success and long postoperative rehabilitation

The reason we get these emails is that for some people, the discussion of the second surgery comes with many concerns. The major concern is that the second surgery may not be successful. For some, that is the only concern. When discussing surgery, it is always best to get surgical opinions and observations from surgeons.

In the journal Clinics in Podiatric Medicine and Surgery, May 2020, (1) the challenges of peroneal tendon revision surgery are described:

“Peroneal tendon tears that require revision are rare and often present a unique challenge for foot and ankle surgeons. Biomechanical issues that may be present or missed initially need to be addressed and evaluated thoroughly for an optimized outcome. Tendon degeneration is usually present, and planning for tendon transfer or tendon graft is necessary to improve mechanical strength. . . The postoperative rehabilitation is often longer and patient education is imperative to manage expectations of outcomes.”

Maybe it is was not the Peroneal Tendon after all – posterior ankle impingement may be the actual cause of pain.

One of the problems of surgery with less than hoped for results is that the surgery may have addressed the wrong problem. That your ankle pain is not really coming from a problem with your peroneal tendon is demonstrated in the title of a June 2020 paper published in the Journal of Clinical Orthopaedics and Trauma (2)  from Texas Children’s Hospital and the University of California at San Francisco. Here three young patients were examined.

“Posterior ankle impingement is a cause of posterior ankle pain common in those who perform frequent plantar flexion activities. Three young patients presented with posterior ankle pain which was initially attributed to peroneal tendon subluxation. However, detailed physical exam and imaging confirmed the diagnosis of posterior ankle impingement as the actual cause of pain.

The peroneal tendon subluxation was not causal (not causing) but an unrelated co-incidental finding. After failed prolonged conservative management (rest, immobilization and physical therapy), the patients underwent posterior ankle arthroscopic debridement for the impingement resulting in return to prior sporting activity without limitation and no recurrence of pain at 19 months follow-up. Posterior ankle impingement diagnosis could be masked by co-incidental asymptomatic peroneal tendon subluxation in pediatric patients.”

Below we will discuss whether similar outcomes can be achieved without surgery.

Continued ankle pain following talus fracture. Was injury to the peroneal tendon missed?

Let’s look at a May 2020 study in the journal International Orthopaedics.(3) Here, surgeons suggest that a lot of peroneal tendon dislocations are being missed following repair of a talus fracture.

Here are the research highlights:

Continued ankle pain following heel fracture. Was injury to the peroneal tendon missed?

A June 2018 study in The Journal of Foot and Ankle Surgery (4) suggested that a lot of peroneal tendon dislocation are being missed following repair of a heel fracture:

Here are the research highlights:

The problem of a missed peritoneal tendon injury in a heel fracture was also reported in The Journal of Bone and Joint Surgery (Amer).(5) Here are the learning points of this research:

The peroneus brevis tendon injury and ankle ligament laxity – you can’t treat one without the other

One of the significant problems we see in the patients who come in for ankle or heel pain with a diagnosis of tendon or cartilage damage is that many do not have any diagnosis or discussion about ligament injury. One of the reasons these people reach out to us is that not only is the missed diagnosis of peroneal tendon damage a problem, but so is the missed diagnosis of ankle ligament injury.

There are two peroneus tendons. One is the peroneus brevis tendon, the shorter tendon that attaches to the outside middle of the foot and the aptly named peroneus longus (longer) tendon which runs under the foot and attaches near the inside of the arch. Injury to either of both these tendons which run down the leg and into the foot parallel to each other can easily be diagnosed as a lateral ankle sprain.

We are going to go back to a 1998 study (6) and then bring it forward 20 years. This study comes from the Department of Orthopaedics, Ostra University Hospital, Sweden. The theme of this study is that you can treat peroneus tendon injury and you can treat ankle ligament injury. But for best affect you must address both. Now this is for people undergoing the first surgery. Not a surgery to correct the first surgery. Let’s examine the study learning points:

Here, the surgeons addressed the problem of ligament laxity of ligament instability causing a hypermobile situation where the peroneus brevis tendon is damaged by an abnormal rubbing against the fibula. The problem is addressed by ligament reconstruction and shaving down bone.

Treating ankle ligaments and peroneus tendons non-surgically

In December 2018, The European Society of Sports Traumatology Knee Surgery and Arthroscopy, published in their Journal of Experimental Orthopaedics(7) these observations on chronic tendon injury. As we pointed out earlier in this article, your situation of continued ankle, heel, and foot pain before and after surgery may be the result of a missed peroneus tendon injury.

These are the learning points of this study:

In the opening of this study, the surgeons acknowledge that helping people with tendinopathy is challenging. Non-surgical methods do not work that well, a 25% failure rate, and surgeries do not typically work that well either. Cortisone is usually not supported and the surgeons question the benefit of PRP injections. Which we will discuss.

In our 27 plus years of helping people with tendon injuries, we have found Prolotherapy and PRP treatments to be effective in helping these people’s goals of getting back to sports or work. The article you have just read is based on our years of experience in treating thousands of patients. The way we offer treatment is not how you may find this treatment offered at other clinics.

In June 2019, this very problem of lack of standardized in treatment was discussed by doctors at the University of Pittsburgh who published this paper: Myths and Facts of In-Office Regenerative Procedures for Tendinopathy: Literature Review., in the American Journal of Physical Medicine & Rehabilitation. Here is what the Pittsburgh doctors had to say:(8)

“Tendinopathy carries a large burden of musculoskeletal disorders seen in both athletes and aging population. Treatment is often challenging, and progression to chronic tendinopathy is common.  . . The field of regenerative medicine has taken the forefront, and various treatments have been developed and explored including prolotherapy, platelet rich plasma (PRP), stem cells, and percutaneous ultrasonic tenotomy. However, high-quality research with standardized protocols and consistent controls for proper evaluation of treatment efficacy is currently needed.”

Basically, there are many practitioners and researchers who are not sure what is the optimal standardized treatment is. In our experience, we find that the optimal standardized treatment is a comprehensive and customized treatment program based on the needs of the individual patient. Someone who runs marathons needs a customized treatment different that someone who simply wants to walk pain free. Your treatment is based on your treatment goals of resuming pain-free activity.

Peroneus Tendinitis and Peroneus Tendinosis non-surgical treatments

By the time a patient comes to Caring Medical with joint problems related to sports, an active lifestyle, or a physically demanding job and their diagnosis of one of the various tendinopathy issues described in this article, many of them will already have an advanced case. It will either be advanced tendinitis or advanced tendinosis. Again, their peroneus tendon problems had been missed and thus, the tendons continued their accelerated degeneration.

A December 2018 study asked the question, “Can Elite Dancers Return to Dance After Ultrasound-Guided Platelet-Rich Plasma (PRP) Injections?” (9) One of the injuries dancers frequently get and was explored was peroneus brevis tendon injury. Here are the summary points of this study:

Here, PRP helped achieve the goal of returning high-level dancers back to dance including those with peroneus brevis tendon injury. We would like to point out that in our experience a more aggressive PRP treatment approach combined with concurrent Prolotherapy treatments may have achieved superior results.

PRP and high ankle sprain

High ankle sprain causes damage to the ligaments that connect the shin bones tibia to the fibula. Because of the high impact stress at the tibia and fibula junction, the syndesmosis joint, the high ankle sprain is difficult to heal. In recent research, doctors examined the success of platelet-rich plasma (PRP) into the injured antero-inferior tibio-fibular ligaments (AITFL) in athletes on return to play (RTP). They further studied the issues of ankle instability and stability before and after the PRP ankle injections.

Sixteen elite athletes with AITFL tears were randomized to a treatment group receiving injections of PRP or to a control group. All patients followed an identical rehabilitation protocol and RTP criteria. Patients were prospectively evaluated for clinical ability to return to full activity and residual pain.

Here are the results:

Athletes suffering from high ankle sprains benefit from ultrasound-guided PRP injections with a shorter RTP, re-stabilization of the syndesmosis joint and less long-term residual pain.(10)

We would like to point out that in our experience a more aggressive PRP treatment approach combined with concurrent Prolotherapy treatments may have achieved superior results.

The treatment begins immediately in the video

This is comprehensive Prolotherapy, meaning there are a lot of injections. The patient getting the injections in this video is comfortable and tolerates the treatment well. The patient in this video is having the lateral or outer ankle treated.

Danielle R. Steilen-Matias, MMS, PA-C. talks about knee pain specifically related to the peroneal nerve.

Hydrodissection procedure

Nerve Release Injection Therapy (hydrodissection) of an entrapped nerve. In this image dextrose solution is injected around the nerve which releases or separates it from the surrounding tissue. The nerve, which is the central circular object has a dark ring forming around it, as seen strongly in the B image. That is the dextrose solution from the needle, the straight image from the right of the screen. The nerve as seen in B is now surrounded by the nerve release fluid and therefore “released.”
