Introduction: The anterior cruciate ligament is well known for its primary restraint on the anterior translation of tibia on femur. It also prevents hyperextension of knee during full extension. It is a secondary stabilizer of the knee against rotational and varus and valgus stress. It is one of the most common ligament injuries of the knee due to its primary role in knee stabilization and its role in knee biomechanics. The current gold standard treatment for anterior cruciate ligament tear is arthroscopic reconstruction, and the most commonly used autografts for primary anterior cruciate ligament reconstruction are bone-patellar tendonbone and four-strand hamstring tendon graft. Materials and Methods: A prospective study was conducted on 30 patients with injured anterior cruciate ligament with or without meniscal injury within the age group of 15-55 years managed with arthroscopic reconstruction of anterior cruciate ligament with hamstring graft and fixed loop endobutton at femoral side and interference screw at tibial side. Functional outcome was assessed using clinical examination, International Knee Documentation committee and Lysholm knee scoring scale. Patients were followed up at 2, 4, 8, 12weeks and 6, 8 months post-operatively. Results: ACL rupture was common in second and third decade of life. In our study, 19(63.34%) were sports related injuries, 8(26.66%) were due to road traffic accidents and 3(10%) were atraumatic degenerations. 24(80%) showed excellent results and 6(20%) showed good results at the end of the study. Conclusion: Arthroscopic ACL reconstruction using hamstring graft and Fixed-loop Endobutton provided excellent post-operative clinical outcome in terms of knee stability, subjective knee function and range of movements of the knee in our study.
