Objective: To determine the functional outcome of arthroscopic anterior cruciate ligament reconstruction (ACLR) using hamstring tendon as autograft and endobutton followed by supervised physiotherapy.
Methods: This descriptive study was conducted in AO hospital Karachi from 2nd April 2017 to 2nd December 2020. All patients with Anterior Cruciate Ligament (ACL) tear meeting the inclusion criteria were operated arthroscopically for anterior cruciate ligament reconstruction (ACLR) using hamstring tendon as autograft and endobutton followed by 6 weeks supervised physiotherapy. The functional outcome was assessed with knee range of motion, Tegner-Lysholm score and International Knee Documentation Committee (IKDC) at 3rd, 6th and 12th months follow up and compared with pre-operative values. P value was calculated with Chi-square test for statistical significance. P value < 0.05 was considered significant.
Results: The total number of patients in our study were 79. The mean age was 25±3 years (range 18 to 40 years).Full range of knee motion (118±60) was achieved in 75(95%) patients. The mean pre-operative IKDC score of 38.95±5 improved to 67.92±2 at 6th months and to 90.73±7 at 12th months follow up. The mean pre-operative Tegner-Lysholm score of 51(poor) improved to 87(good) at 6th months and 97(excellent) at 12th months. The Lachman’s test and pivot shift test was negative in all patients postoperatively and 56(70.8%) patients could performed single legged hopping test without any difficulty at 6th months post operatively.
Conclusion: Anterior Cruciate Ligament Reconstruction (ACLR) using hamstring tendon autograft with endobutton fixation and supervised rehabilitation yielded excellent functional outcomes in majority of our patients. We therefore recommend this protocol as treatment of choice for all patients with ACL tear.
