Abstract

In patients complained of lateral ankle pain, the peroneal tendinopathy is frequently overlooked because relatively rare. In this study, types of lesion, frequency, and clinical results were analyzed in patients with peroneal tendinopathy associated in chronic ankle instability. This study reviewed the result of 22 patients. The average age was 35.1 years with an average follow-up of 20.1 months. Modified Brostrom procedure was done and peroneal tendon was explored. Peroneal tendinopathy was composed of 9 tear, 2 dislocation, 4 tendinitis, 7 low-lying muscle belly, 1 peroneal quartus. Depending on the type of peroneal tendinopathies, tubularization, groove deepening and retinaculum repair, and debridement were done. All patients had a history of repeated sprains, positive anterior drawer test, lateral ankle pain. After the last follow-up, the visual analogue scale score and American Orthopaedic Foot and Ankle Society score were evaluated. Also, almost of all patients were satisfied and anterior drawer test was improved. If the patients have chronic ankle instability and pain around the retromalleolar area, we keep in mind that the lesions are peroneal tendinopathy.
