Lateral ankle ligament reconstruction using the anterior half of the peroneus longus tendon

The purpose of this study was to assess the results of a novel surgical technique for the treatment of chronic lateral ankle instability with attenuated or deficient ligamentous tissue that the modified Brostrom procedure could not be performed. A lateral ankle ligament reconstruction using the anterior half of the peroneus longus tendon has been performed. Thirty-four consecutive patients treated with lateral ankle ligament reconstruction using anterior half of the peroneus longus tendon were enrolled. Median age at surgery was 24 years (range 19-46 years). The clinical and radiologic outcomes were evaluated preoperatively and at a median of 21 months (range 12-51 months) follow-up. The Karlsson-Peterson ankle score significantly improved from 58.2 +/- A 10.9 points preoperatively to 83.9 +/- A 7.0 points at the last follow-up. Mechanical stability was achieved. The mean talar tilt angle significantly improved from 15.7A degrees A A +/- A 3.5A degrees preoperatively to 4.6A degrees A A +/- A 1.7A degrees at the last follow-up, and the mean anterior talar translation significantly improved from 7.3 +/- A 2.6 mm preoperatively to 4.1 +/- A 1.7 mm at the last follow-up. Fifteen patients (52 %) were very satisfied with the results, nine patients (31 %) were satisfied, four patients (14 %) were fair, and one patient (3 %) was dissatisfied with the results. Lateral ankle ligament reconstruction using the anterior half of the peroneus longus tendon can be a surgical option for chronic lateral ankle instability with attenuated or deficient ligaments.
