Recurrent subluxation of the peroneus longus tendon in a young adult: A case report and review of literature

Abstract

Recurrent peroneal tendon subluxation is a relatively uncommon sports injury often seen in young adults and associated with skiing, ice-skating and soccer. Acute subluxations are often missed and leads to chronic recurrent subluxations. Pre-disposing anomalies include peroneus brevis defects, convex retro-fibular groove, weak superficial peroneal retinaculum and pre-existing tendinopathy. Chronic subluxations require operative management which includes groove deepening procedures, soft tissue repairs or bone block procedure. We report a young adult presenting with recurrent peroneal tendon subluxation with pre-existing anomalies. A combined surgical technique was used and results followed up at 2, 6 and 12 months. We also review previous literature of similar procedures to compare outcomes.
