Multicenter Clinical Study on Robotic-Assisted Surgical Management of Posterior Cruciate Ligament Tibial Avulsion Fractures

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.
