Postoperative complications, such as knee instability and limited range of motion (ROM), always happen during the rehabilitation period of posterior cruciate ligament avulsion fracture (PCLAF), making poor prognosis. Arthroscopic double row anchor suture bridge fixation is a new technology for PCLAF. This study aims to clarify the safety, efficacy, and functional prognosis of suture bridge fixation for treating acute PCLAF. The posterior drawer test (PDT) and posterior displacement distance were performed and measured to evaluate the stability of the knee joint, with other parameters including knee ROM, as well as IKDC, Lysholm scores, and rate of returning to sports for evaluating the prognosis. The results showed that the bone healing process was good at 3 months after surgery and the positive rate of PDT, degree of displacement, ROM, Lysholm, and IKDC scores were recovered well at both 1 and 1.5 years after surgery, without intergroup difference. However, the rate of returning to sports at 1.5 years after surgery was significantly higher than the rate at 1 year after surgery. The present study indicates that acute PCLAF patients can obtain good bone healing progress and smooth post-operative rehabilitation by arthroscopic suture bridge fixation, and that the joint function can be restored within 1 year after surgery and 76.5% of the patients can return to physical exercise in 1.5 years, suggesting a good prognosis.
