The knee joint is one of the strongest and most important joints in the human body. It allows the lower leg to move relative to the thigh while supporting the bodyââ¬â¢s weight. Movements at the knee joint are essential to many everyday activities, including walking, running, sitting and standing. The knee, also known as the tibiofemoral joint, is a synovial hinge joint formed between three bones: the femur, tibia, and patella. Two rounded, convex processes (known as condyles) on the distal end of the femur meet two rounded, concave condyles at the proximal end of the tibia. The patella lies in front of the femur on the anterior surface of the knee with its smooth joint-forming processes on its posterior surface facing the femur.
