Functional Outcomes after Posterior Cruciate Ligament Arthroscopic Reconstruction Surgery

Background: The posterior cruciate ligament (PCL) primarily stabilizes the knee joint’s posterior part. PCL protects against tibial posterior translation and rotational instability by working together with the components of the posterolateral corner (PLC). PCL reconstruction has advancements; however, current approaches didn’t yield consistent results. Objective: To assess a functional outcome of patients after PCL reconstruction. Methods: A case series study was conducted from Jan 2021 till Jan 2022. We enrolled 10 participants with PCL injuries, ages between 25 and 36 years, late presentation more than 1 month, and excluded those with degenerative changes, multi-ligament injury, and limb malalignment. PCL reconstruction was performed. Knee arthroscopy was conducted to discover the PCL disfigurement. The Lysholm score was evaluated preoperatively and 6 months postoperatively. It ranges from 0 to 100 points. A score of 95-100 means excellent, 84-94 means good, 65-83 means fair, and 65 means poor. Results: The mean Lysholm score preoperatively was 60.7 and postoperatively was 89.4, with a significant difference. A significant correlation was found between age and Lysholm score after surgery, where younger age was associated with better functional outcomes. Conclusions: Age plays a role in the improvement of the Lysholm score postoperatively. The timing of PCLR surgery doesn’t affect the functional outcome when done for less than or more than six months.
