Purpose: The goal of this study was to evaluate the clinical outcome of single-bundle posterior cruciate ligament (PCL) reconstruction with retention of the PCL remnant and hamstring tendon autograft with interference screw fixation in patients with isolated PCL laxity. Type of Study: Prospective case series with minimum 2-year follow-up evaluation. Methods: Thirty-one patients for whom conservative management had failed underwent surgery using a 4-strand hamstring tendon autograft with interference screw fixation. The median time from injury to reconstructive surgery was 9 months (range, 4 to 120 months). At a minimum of 2 years after surgery, patients were assessed with the International Knee Documentation Committee (IKDC) Knee Ligament evaluation, Lysholm knee score, and KT-1000 instrumented testing. Results: Before surgery, the median Lysholm knee score was 64 (95% confidence interval, 51 to 67). No patient rated knee function as normal, and all patients showed at least grade 2 posterior drawer laxity. At review, the median Lysholm knee score was 94 (95% confidence interval, 83 to 94), 56% rated the knee as normal and only one patient was found to exhibit grade 2 laxity on posterior drawer testing. Before injury, 94% of patients participated in moderate or strenuous activity. This figure fell to 26% after injury and had increased to 63% at review. Conclusions: Endoscopic reconstruction of PCL laxity using single-bundle 4-strand hamstring tendon autograft, without removal of the PCL stump, provides a significant reduction in knee symptoms and allows 63% of patients to return to moderate or strenuous activity. This is an effective procedure for symptomatic patients who have isolated PCL laxity and for whom conservative management has failed.
