Objective: To retrospectively evaluate the functional outcome after arthroscopic single bundle posterior cruciate ligament (PCL) reconstruction in patients with PCL injuries with single bundle autogenous hamstring graft using International Knee Documentation Committee (IKDC) subjective knee evaluation and Lysholm Knee scoring scale. Methods: This was a retrospective study of 42 patients who underwent arthroscopic This study was a retrospective observational analysis on a series of 42 patients who underwent primary posterior cruciate ligament reconstruction for isolated grade III and above PCL injuries. The diagnosis was mainly based on clinical tests demonstrating the signs of posterior and rotational knee laxity (Sag test, Posterior drawer test, Lachman Test) and subjective complains of the patients reporting instability of the affected knee. The mean age was of 34.79+/-6.88 years (range: 15 to 65), with male predominance 39 (92.85%) and twenty four cases left shoulders, with RTA (28:65.11%) being the most common mode of injury. Arthroscopic PCL reconstruction was performed in all patients after a mean of 15.5 months of injury (range: 2wks to 33 months) with a mean follow-up of 20.9months (range: 8to38months). Results: There was a significant difference between the pre-and postoperative functional outcome (p < 0.001).The Lysholm score at final follow-up was 90+/-3.87(range:81-96) compared to a preoperative score of 71+/-6.70(range:42-78).The IKDC score at final follow-up was90+/-3.65(range:80-95),compared to a preoperative score of 71+/-7.62(range:42-77). Conclusion: Thus it can be concluded that transtibial single bundle PCL reconstruction with hamstring graft resulted in satisfactory clinical, function all outcomes.
