Meniscus Resection: A Guide to Meniscus Resection

To understand the dangers of meniscectomy, it is important to understand the role of the meniscus. The meniscus acts as a buffer between the femoral condyle and tibial plateau, protecting both articular surfaces and absorbing downward vibrations, especially during excessive knee flexion or extension. In addition, the meniscus prevents the femoral condyle from sliding forward on the tibial plateau and regulates pressure in the knee joint. The meniscus also supports knee rotation and assists the medial and lateral collateral ligaments in controlling lateral movement of the joint, helping with rotational movement. When the meniscus ruptures due to trauma, it has to be removed. After surgery, these functions of the meniscus will be lost, and the degeneration of the knee joint will be accelerated, resulting in early osteoarthritis of the knee joint, thus causing pathological changes such as knee joint deformation and pain.
