Background: Anterior cruciate ligament reconstruction is the most commonly reconstructed ligaments of the knee. This study attempts to analyse the functional outcome of ACL reconstruction and the parameters utilized commonly to assess the outcomes.

Methods: This is an analysis of 25 patients who underwent ACL reconstruction, who were operated by a single surgeon, and were studied for a period of one year .Analysis was made using standard scoring systems like Lysholm and IKDC score by an independent observer over a period of one year.

Results: The injury was commonly noted in the male gender although the sidedness of the injury did not seem to influence the outcome. The larger percentage of cases was operated less than 6 months from the date of injury. The mean graft diameter was 7.9 mm, with a positive correlation to the thickness of the thigh. The preoperative mean Lysholm score of 58.76 improved to 91.16 after surgery. The mean preoperative IKDC score improved from 29.26 to 58.70. One patient had infection and two had stiffness and reduced range of motion. The timing of surgery and rehabilitation influence the outcome largely.

Conclusions: Anterior cruciate ligament reconstruction surgery with quadrupled hamstring grafts provides a good outcome to ACL injuries when the surgery is timed well, with sufficient graft thickness and good rehabilitation.
