Anatomical reconstruction of the lateral ligaments of the ankle with semitendinosus allograft.

PURPOSE: The purpose of our study is to evaluate the clinical results of anatomical reconstruction of the lateral ligaments with semitendinosus allograft.

METHODS

Thirty-six patients with chronic lateral instability underwent anatomical reconstruction of the lateral ligaments of the ankle with semitendinosus allograft. The American Orthopaedic Foot and Ankle Society Ankle-Hindfoot Scale score (AOFAS score) and the Karlsson score were used to evaluate the clinical results before and after surgery.

RESULTS

A total of 35 patients (97.2 %) (36 ankles) were followed up for a mean of 37.9 months. The mean AOFAS score improved from 42.3 ± 4.9 points preoperatively to 90.4 ± 6.7 postoperatively. The mean Karlsson score improved from 38.5 ± 3.2 preoperatively to 90.1 ± 7.8 postoperatively.

CONCLUSIONS

Anatomical reconstruction of the lateral ligaments with semitendinosus allograft achieves a satisfactory surgical outcome for chronic ankle instability.
