Chronic ankle sprain and instability treatment

In this article Ross Hauser, MD discusses chronic ankle sprain treatment, the problems of diagnosing ankle sprains and long-term non-surgical options including the use of Prolotherapy, Platelet Rich Plasma Therapy, and Stem Cell Therapy. Highlights of this article:

Chronic ankle sprains and instability

Chronic ankle sprains can be tricky to diagnose and treat. Ankle instability may not show up after the first acute ankle sprain and there is no consensus on how to tell if a patient will have instability in the future.Unfortunately, literature examining chronic ankle instability  is conflicting and confusing to patients.2

New research make this clear.

I agree there. What I do not agree with is many cases is the recommendation to surgery should ankle instability develop.

Let’s do a medical equation and combine the research of two studies. Above the German doctors said the simple ankle sprain that looks like it healed should be monitored to prevent it from becoming a potentially complicated sprain which is at risk of transition to chronic ankle instability. In the British Journal of Sports Medicine researchers said says that a new ankle injury is not always a new or  acute one, but one that can be identified as an old chronic injury with an increase in symptoms.4

Researchers are showing that doctors should be aware that chronic ankle instability can be a problem of an injury that never heals.

We get a good idea who has instability or is at risk for chronic ankle sprain when we see a patient who feels that their ankle is “giving way”, have constant swelling, obvious pain, decreased range of motion or excessive motion from ankle instability. They often ask what is causing their “weak ankles,”  the continued “popping,”and “clicking” sound they hear. The patients know the ankle is not right.

A good summary of chronic ankle instability

In new research surrounding male soccer players doctors had this to say:

Knee, Hip, Ankle and Balance problems

One curious symptom and one that should clearly point to chronic ankle instability and should be explored in patients with chronic knee instability and hip instability is Dynamic balance deficits.

In two studies from Ireland, patients who suffered from an acute ankle sprain were followed and tested for problems of balance. Not only were their injured ankles tested but also the same side knees and hips. At 6 months follow up and one-year follow up after a single ankle sprain event, patients showed reduced balance that created stress on the entire limb side, hip, knee, and ankle included.6,7

The first ankle sprain

The most common type of ankle sprain is from a “rolled ankle” an inversion injury, turning the ankle inward, injuring or tearing the ligaments on the lateral side of the ankle, usually the anterior talofibular and the tibiofibular ligaments. Many times a patient will report that they simply “twisted” their ankle without realizing the structural damage that could have been done.

The inside of the ankle is held together by a group of ligaments called the deltoid ligament. This ligament is injured from turning the foot outward, as can happen when falling down stairs or mis-stepping. Once an ankle is sprained, the injury may take a few weeks to many months to fully heal. The injured ankle often remains a little weaker and less stable than the uninjured one.

Ankle sprains are either undertreated or overtreated. . . This is an  injury that doctors should be acutely aware of and successfully able to evaluate and treat. 8

Left untreated, ankle instability leads to cartilage deterioration with resultant degenerative arthritis. If a ligament does not heal, joint instability occurs and the end-result is arthritis with good prospects for fusion or ankle replacement surgery. Treated with  stronger NSAIDs or cortisone shots can also lead the patient to surgery.

Cortisone has been shown to further degenerate the injured ligaments in joints, leading the patient towards osteoarthritis. Once diagnosed with osteoarthritis that is seemingly irreversible, the words “ankle fusion,” “ankle arthroscopy,” and “ankle joint replacement” are introduced into the consultation.

Ankle Instability and Prolotherapy

This section will deal with the question, How do you treat a sprained ankle?

Caring Medical’s first line of treatment for chronic ankle pain – ankle instability is Prolotherapy. In treating with Regenerative Injection Techniques (RIT), i.e., Prolotherapy, Platelet Rich Plasma Therapy, and Stem Cell Therapy, a comprehensive approach must be taken. This means treating the whole ankle, not just a single injection at a single site in the joint, as some physicians attempt to do. The comprehensive problem of ankle instability requires a comprehensive treatment. Here’s what current research reveals about ankle instability and injury and how a doctor should consider treatment:

Writing in the medical journal Practical Pain Management, we reported on patients surveyed following Prolotherapy ankle treatments. These patients said they had less pain, stiffness, crepitating, depressed and anxious thoughts, medication usage, as well as improved range of motion, walking ability, sleep and exercise ability.

Overall average pain levels dropped significantly after treatment. This study included patients who were told by their medical doctor(s) there were no other treatment options for their unresolved ankle pain or that they needed surgery.

Ninety percent of the participants experienced 50% or more pain relief.  

Prolotherapy helped the patients make significant improvement in stiffness, range of motion, exercise ability, activities of daily living and walking ability, as well as decreasing their levels of anxiety and depression. Prolotherapy helped all patients on pain medications reduce the amount of medications taken.9

For significant deterioration, we may recommend to patients a more aggressive approach incorporating Platelet Rich Plasma and Stem Cell Therapy injections.

PRP Ankle Injection Research on high ankle sprain

A less common but well known ankle injury is the “high ankle sprain.” This is 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 difficulty 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
