OSG-Prothese bei Varusinstabilität - eine neue Möglichkeit der Korrektur

In a prospective series of 100 total ankle arthroplasties 8 patients had a lateral instability > 20° (20°- 35°). In 1 case the reconstruction was done by shortening of the capsule and refixation to the anterolateral corner, in 7 cases (4 ♂, 3♀) the reconstruction was done by a transfer of the peroneus brevis tendon from posterior into in a fibular groove, which is created at the anterior edge of the fibula. Fixation was performed with two suture anchors. The reconstruction is done extraarticular. The clinical and radiological follow up examination was done 3 - 24 month after the index surgery. In all patients there was a complete restoration of the lateral stability, and the average ROM of the ankle joint was 48° (38 - 64). There were no intra- or postoperative complications
