POSTERIOR CRUCIATE LIGAMENT INJURY OF THE KNEE JOINT DIAGNOSIS AND ARTHROSCOPIC SURGERY

Among knee joint injuries, posterior cruciate ligament (PCL) injuries—especially in isolated cases—occur less frequently compared to anterior cruciate ligament (ACL) injuries. Regardless of age or gender, the annual incidence is approximately 2 per 100,000 people.
The PCL serves as the primary stabilizer against posterior translation of the tibia. Anatomically and biomechanically, it can be divided into two bundles: the anterolateral (AL) bundle and the posteromedial (PM) bundle.
In general, isolated PCL injuries are difficult to diagnose and are often identified late or may even remain undiagnosed.
Anterior-posterior stress radiography is a commonly used diagnostic method for accurately detecting chronic PCL injuries.
Conservative treatment for PCL injuries can yield relatively good clinical outcomes, but accurate diagnosis is critical. Key factors include the timing of the injury, the degree of posterior tibial translation, and whether other ligaments are also involved.
In our surgical approach, we preserved the anatomical graft insertion on the tibia, eliminating the need for additional tibial fixation. As a result, we were able to reduce both operative time and material costs. This also contributed to earlier graft tenodesis and faster rehabilitation for the patient.
