Abstract
Aim: Isolated posterior cruciate ligament (PCL) injuries are considered as benign and treated conservatively. Aim of this study is to determine the functional outcomes, efficacy of isolated PCL injuries treated by arthroscopic PCL reconstruction or fixation. Materials and Methods: A total of 24 patients, each with an isolated PCL injury, (17 with complete PCL tear and 7 with PCL avulsion fracture) were enrolled in this prospective study. Patients with complete tear underwent PCL reconstruction with hamstring tendon autograft and the patients with displaced avulsion fractures underwent arthroscopic fixation with suture bridge technique. The patients underwent regular follow-up postoperatively with clinical and radiographic evaluation. Follow-up examinations comprised the Lysholm knee score, International Knee Documentation Committee (IKDC) score. Results: Mean pre-operative lysholm score for 24 knees was 41; mean post-operative lysholm score was 90. 18 of 24 patients had excellent results, 4 patients had good results, and 2 patients had fare result at final assessment. In final IKDC ratings, 21 patients were assessed as normal or near normal (Grade A or B). Conclusions: The short-term follow-up showed good function after arthroscopic management in isolated PCL injuries. Hence, we recommend surgical intervention in isolated PCL injuries
