Arthrodesis of the knee, commonly known as knee fusion, is a surgical procedure aimed at permanently joining the bones of the knee joint. This procedure is primarily indicated for patients who have experienced failure of a total knee replacement, where the artificial joint has not functioned as intended. The goal of knee arthrodesis is to alleviate pain and restore stability to the knee by eliminating the joint space, thereby preventing further movement that could cause discomfort. Various techniques can be employed during the procedure, including internal fixation, external fixation, and the use of bone grafts to facilitate the fusion process. The procedure typically begins with the removal of the failed total knee prosthesis, which is a separately reportable surgical intervention. Following this, the surgeon exposes the vascular bone on both the femur and tibia, preparing them for fusion. The alignment of the joint is carefully considered, with specific angles of valgus and flexion to ensure optimal positioning for healing. Overall, knee arthrodesis is a complex procedure that requires meticulous planning and execution to achieve successful outcomes for patients suffering from severe knee issues.
