Background:
Achilles tendinopathy is a common clinical problem that can be either insertional or noninsertional. A variety of treatment methods have been described, although little consensus exists on an optimal method or methods. We sought to investigate the current evidence on different treatment methods for noninsertional Achilles tendinopathy, with a focus on functional outcomes.
Methods:
We performed a review of the available literature in PubMed and the Cochrane Central Register of Controlled Trials. Data from included studies were categorized according to treatment method and analyzed with respect to functional outcome and complication rate.
Results:
In total, 1420 abstracts were reviewed, of which 72 articles containing 3523 patients met inclusion criteria. Within the 72 studies included, 6 operative techniques and 19 nonoperative treatments were evaluated.
Conclusion:
A wide variety of treatments are available for noninsertional Achilles tendinopathy, although newer treatments and most operative methods lack high-level evidence. Eccentric exercise is the most thoroughly studied and supported nonoperative treatment, while tenotomy and debridement is the operative procedure with the most evidence of efficacy. Platelet-rich plasma injections and extracorporeal shockwave therapy have proven to be viable second-line nonoperative treatments. Gastrocnemius recession and flexor hallucis longus transfer have shown benefit in case series.
Level Of Evidence:
Level II, systematic review.
