Inclusion Criteria: * A clear diagnosis of posterior cruciate ligament (PCL) tibial avulsion fracture, verified through preoperative radiographs and computed tomography (CT), with classification as type II or III based on the Griffith system (a modified Meyers and McKeever scale). * Patients aged 18 years or older. * Surgical management within two weeks post-injury. * Absence of additional ligament or meniscal injuries in the affected knee, confirmed via magnetic resonance imaging (MRI). Exclusion Criteria: * Concurrent ligament or meniscal injuries in the affected knee, confirmed via MRI. * Prior surgical procedures or traumatic injuries involving the same knee. * Severe systemic diseases that could interfere with surgical outcomes (e.g., uncontrolled diabetes, severe cardiovascular disease). * Insufficient clinical or radiographic follow-up data. Additional Information: In total, 17 patients (9 males and 8 females), with an average age of 49 ± 12 years, who satisfied all inclusion and exclusion criteria, were ultimately included for analysis.
