Favorable change in patient-reported outcomes following peroneus longus to brevis tendon transfer and lateral ankle ligament reconstruction.

BACKGROUND

A peroneus longus to brevis tendon transfer is recommended for a severely torn peroneus tendon, but there is little research on the outcome. We conducted a prospective cohort study to examine patient-reported outcomes after this procedure.

METHODS

Thirty-two patients underwent a peroneus longus to brevis tendon transfer and lateral ankle ligament reconstruction, 11 had an additional calcaneal osteotomy. The Foot and Ankle Outcome Score (FAOS) and Short Form-36 (SF-36) were assessed preoperatively, six and 12 months after surgery.

RESULTS

Preoperative mean FAOS was 51.7 (SD 17.8) compared with 72.7 (SD 21.2) at 12 months, an improvement of 21 (95 % CI 12.7-28.0) (p < 0.0001). SF-36 improved significantly in the three domains involving physical function and bodily pain (p < 0.007).

CONCLUSION

Patient-reported outcomes improved significantly through peroneus longus to brevis tendon transfer. This procedure is worth considering for patients with a severely damaged peroneus tendon.
