The femoro-tibial joint is a flexion joint and is the main joint of the knee joint, performing mainly flexion and extension movements, with rolling, sliding and rotational movements in the vertical axis. The knee joint consists of the femoro-tibial joint and the femoro-patellar joint, with the femoral and tibial plateaus forming the femoro-tibial joint. The articular surface of the tibiofemoral joint is characterized by its large, complex and inconsistent shape, with the femur sloping medially at the knee joint and the tibia almost vertical. The femoro-tibial joint plays a large role in the knee joint, and in patients with knee dysfunction, long-axis traction can be applied to the femoro-tibial joint to relieve knee pain. When the traction activity is anterior-posterior sliding, it increases the range of motion of knee extension, and when posterior-anterior sliding, it increases the range of motion of knee flexion, which facilitates the recovery of patients with knee dysfunction. Another common disease that occurs in the tibiofemoral joint is degenerative osteoarthritis, which is a disease based on degenerative pathological changes in the knee. The symptoms of degenerative knee osteoarthritis are mostly in the middle-aged and elderly population and are characterized by redness, swelling and pain in the knee, pain when going up and down stairs, and soreness and discomfort in the knee when sitting and standing up. Some patients also show symptoms such as swelling, popping and fluid accumulation, which can easily cause joint deformity and disability if left untreated.
