ABSTRACT

Background: Soft tissue injuries particularly ligaments & tendons, are the most common injuries in sports & often require orthopedic surgery. Among them the Anterior Cruciate Ligament is one of the most injured knee joint structure. The Peroneus longus tendon has been used as a graft in many orthopaedic surgical procedures because of it’s comparable biomechanical strength with the native ACL. Objective: The aim of this study was to evaluate the functional outcome of Arthroscopic Anterior Cruciate Ligament Reconstruction by Peroneus Longus Tendon Autograft. Methods: This prospective interventional study was conducted from July 2019 to June 2021 at Dhaka Medical College Hospital, Dhaka. Within this period, Twenty (20) patients with ACL injury that required reconstruction surgery was selected as per inclusion criteria as a study sample. Pre-operative clinical tests & investigations were done to confirm tear. Reconstruction was done by Peroneus Longus tendon autograft arthroscopically. Results: The mean age of patients was 27.35±4.030 with male predominance (90%). Maximum study patients had injured from sports injury (60%). The mean diameter of peroneus longus tendon autograft was 8.25±0.414 mm. Almost all the patients in our study showed significant improvement of their functional capability at 6 months after the surgery with P value <0.05. Pre-operative Lachman test was positive grade 3+ in 70% cases which was improved post operatively and negative in 95% cases, pre-operative anterior drawer test was positive in 100% cases while post operatively at final follow up majority (95%) were negative, Lysholm score improved from 56.85±7.30 to 92.35±6.115, preoperatively which was poor in 85% cases while were good or excellent in 95% cases at final follow-up. The mean for the AOFAS score at final follow up was 96.75±5.711, Majority study patients (95%) had good or excellent AOFAS score on final post-operative assessment. Conclusion: After analyzing the results of study, it can be concluded that Arthroscopic ACL reconstruction by peroneus longus tendon autograft is an effective treatment option without compromising ankle function & avoiding potential complications of autografts obtained from knee region.
