    Abstract:
    OBJECTIVE: To investigate the clinical effect of arthroscopic fixation of tibial avulsion fracture of posterior cruciate ligament with a knot-free anchor and Endobuton titanium plate. METHODS: From October 2019 to October 2020, 12 patients with tibial avulsion fracture of posterior cruciate ligament were treated with the arthroscopic knot-free anchor and Endobuton titanium plate, including 9 males and 3 females. The age ranged from 23 to 58 years old. The time from injury to operation ranged from 2 to 9 days. There were 2 cases of Meyers typeⅡand 10 cases of Meyers type Ⅲ. There were 2 cases of meniscus injury and 1 case of partial injury of medial collateral ligament. The fracture healing and knee range of motion were evaluated after operation, and the clinicalefficacy was evaluated by Lysholm function score. RESULTS: All patients were followed up for 12 months. All patients healed within 6 months, and there were no complications such as incision infection, lower extremity deep venous thrombosis and internal fixation falling off. The knee flexion range of motion recovered from 50°-90° before operation to 115°-130° 6 months after operation, and no patient had straightening disorder. Lysholm functional score recovered from preoperative 29-54 scores to 86-100 scores 12 months after operation. CONCLUSION: Arthroscopic reduction and fixation of tibial avulsion fracture of posterior cruciate ligament with the knot-free anchor and Endobuton titanium plate has less complications, high fracture healing rate, good extension and flexion angle and early function recovery of knee joint.
