Open reduction and internal fixation surgery: Control group: incisional reduction and internal fixation surgery
Study summary
The primary objective of this clinical trial is to evaluate the efficacy of robotic-assisted surgery in the management of posterior cruciate ligament (PCL) avulsion fractures involving the tibial insertion site of the cruciate ligament. Specifically, the study seeks to determine: (1) whether robotic-assisted surgery yields superior anatomical reduction accuracy-particularly in restoring the native position of the tibial avulsion fragment-compared with conventional open reduction and internal fixation (ORIF); and (2) whether such improved precision translates into enhanced long-term functional recovery of the knee joint.

Inclusion Criteria:
* Age ≥ 18 years
* Acute closed tibial avulsion fracture, with surgery performed within 3 weeks of injury ③ Radiographically confirmed Meyers-McKeever classification Type II or III fracture ④ Absence of absolute contraindications to surgical intervention ⑤ Provision of voluntary, written informed consent prior to enrollment
Exclusion Criteria:
* Pathological fractures or complex ipsilateral injuries, including concomitant fractures at other anatomical sites.
* Prior ipsilateral knee joint surgery. ③. Significant vascular or neurological compromise.
* Acute meniscal tears, acute anterior cruciate ligament (ACL) ruptures, or acute injuries to the medial or lateral collateral ligaments.
* Compromised local soft tissue integrity, including open fractures. ⑥. Withdrawal from the study or loss to follow-up despite having provided written informed consent.
Primary outcome measure(s)
the quality of surgical reduction — 72 hours (±24 hours) after the surgery In the CT scan images obtained approximately 72 hours (±24 hours) after the surgery, the maximum distance between the fracture fragments was measured on the sagittal plane.
