Abstract: Background: Multiligament injury (MLI) with posterolateral corner (PLC) involvement of the knee present significant diagnostic and management challanges. Multiple techniques has been describe for managing these injuries. The Larson technique, a fibula based approach, is an acceptable method that provides adequate stability. This study evaluates the functional outcomes of MLI reconstruction using the Larson technique with an allograft. Methods: A retrospective review of MLIs managed with the Larson procedure between January 2021 and December 2023 was conducted. Patient?s demographic, ligament involvement, and preoperative and postoperative lower limb extremity score (LEFS) were evaluated. Results: Nine cases (one female, eight male) were included. Among them, two (22.2%) involved PCL and PLC, while seven (77.8%) involved ACL, PCL and PLC injuries. The mean preoperative LEFS score was 47.67, improving significantly to 65.22 postoperatively (p<0.018). Most patients experienced improved functional outcomes, with 66.7% achieving minimal or no functional limitations. Conclusion: In a population with lower activity demands, the Larson technique offers satisfactory functional outcomes and adequate stability in MLI cases involving PLC injuries.
