Short-Term Clinical Outcome of ACL Reconstruction Using Peroneal Longus Tendon Auto Graft

The anterior cruciate ligament (ACL) reconstruction is one of the most frequent surgeries on the adult knee. Auto grafts are essential for providing knee stability while minimizing donor site morbidity. The peroneus longus tendon may be an alternative auto graft for ACL reconstruction. This study aimed to evaluate the short-term clinical outcomes and donor site morbidity of ACL reconstruction using the peroneus longus tendon.

This cross-sectional study was conducted on patients with an ACL tear, who underwent arthroscopic reconstruction using the peroneal longus tendon. The knee functional outcomes were investigated based on the Lysholm and IKDC scores at preoperative and end of at least one year after the procedure. The follow-up period was at least one year, and the graft diameter was measured intra-operatively. In addition, the American Orthopaedic Foot and Ankle Score (AOFAS), the Foot & Ankle Disability Index (FADI), and ankle range of motion were applied to evaluate ankle donor site morbidities.

A total of 50 patients (47 men and three women) were followed up for at least one year with a mean age of 24.2 years (17 to 50 years old). The mean follow-up time was 19 months (12-24 months). The mean diameter of the peroneal longus auto graft was 8.22 ± 0.5 mm (7-9 mm). The AOFAS, FADI and ankle range of motion indicated no obvious ankle joint dysfunction.

According to the results, arthroscopic anterior cruciate ligament reconstruction with the peroneal longus tendon is be a safe and effective auto graft source.
