Arthroscopic Internal Brace Augmentation With Arthroscopic Modified Broström Operation for Chronic Ankle Instability

Abstract Lateral ankle sprains are very common injuries that sometimes lead to chronic lateral ankle instability. The modified Brostrom operation is the gold standard procedure for treatment of chronic lateral ankle instability. Currently, this operation is performed arthroscopically. Brostrom repair depends on the quality of the remnant ligament. In cases with an insufficient remnant ligament, Gould augmentation or reconstruction using the gracilis tendon is generally performed. Recently, tape augmentation (internal brace) also has been used to support an insufficient ligament. This article introduces arthroscopic tape augmentation with arthroscopic modified Brostrom operation. This technique consists of creation of a talar anchor hole and fibular anchor hole, reattachment of the remnant ligament to the fibula with tape, and tape fixation to the talus. This technique uses only one knotless anchor screwed to the fibula for both the modified Brostrom operation and fixation of the tape. This technique is relatively simple and produces similar results as an open procedure.
