Background:Arthroscopic anterior cruciate reconstruction has become one of the most successful surgical techniques in sports medicine however initial secure graft xation is essential for the success of any ACL reconstruction. Objective: The study was done to evaluate the functional outcome of arthroscopic ACLreconstruction using hamstring graft xed with suspension button for femur and interference screw for tibial xation. Material And Methods: From 2017 to 2018 January in Sree Gokulam Medical College Venjaramoodu, Trivandrum, 48 patients underwent ACL reconstruction using semitendinous graft xed with suspension button at femur and interference screw at tibial site. 8 patients were excluded from the study. The age group in our study was between 20-50 years of age. We assessed the patients preoperatively and postoperatively with 6 and 24 months interval by IKDC knee score 2000. Results: Our study showed that Arthroscopically assisted ACL reconstruction could effectively improve stability and function of knee joint. In our study IKDC score was done at pre op and post-op with 6 and 24 months interval. Mean average IKDC score was 38.995 during the preoperative period, at 6 months was 55.253 and 24 months was 88.111. On comparison of the mean values for IKDC scoring for (a) preoperative period to 6 months was 16.258, (b) preoperative period to 24months was 49.116 and (c) 6 months to 24 months postoperative period was 32.858. The P values for all these comparisons were <0.001, hence signicant. There were eleven Isolated ACL injuries who had pre-op , six and twenty forth month post-op functional score of 44.04,63.35 and 90.259 respectively. Ten ACL with lateral meniscus injuries had pre-op , six and twenty forth month post-op functional score of 35.62, 53.85 and 88.348 recpectively. Nineteen ACL with medial meniscal injuries had pre-op , six and twenty forth month post-op functional score of 37.85, 51.30 and 86.74 respectively. Conclusion: Isolated ACL had better functional score. The improvement in the IKDC score was during the 6-24 month range. When ACL with meniscal injuries were compared, the one with ACLreconstruction and lateral meniscetomy showed better outcome.
