Comparative study of the functional outcome of semitendinosus graft versus peroneus longus graft in arthroscopic reconstruction surgeries of anterior cruciate ligament

Background: ACL disruption is the commonest ligamentous knee injury among active adults, invariably leading to changes in kinematics which are most likely result secondary degenerative and long-term functional impairment. Thus, due ACL's crucial role as primary restraint against anterior tibial translation, its reconstruction using varying graft options being extensively studied for better outcome. Methods: In this prospective study, we analysed 30 patients having tear (clinically radiographically) treated with arthroscopic of ACL. Among these, 15 cases were operated semitendinosus by peroneus longus tendon graft. The study was conducted a tertiary care hospital from January 2021 June 2022 minimum follow up 6 months maximum months. Results: Mean Lysholm score (post op) Group ST 90.6±3.18 PLT 92.2±2.65. Score IKDC grading between two groups comparable showed no significant difference. Post-Op laxity assessed Lachman’s normal findings 70% patients, remaining 30% (9 patients), 5 group 4 1+ at examination. Conclusions: Arthroscopy assisted autograft provides steady knee, reduces postoperative donor site morbidity enables early rehabilitation, similar traditional autograft.
