[0002] The hip joint is a ball-and-socket joint composed of the acetabulum and femoral head. Its joint capsule is thick and strong, reinforced by ligaments. It allows for multi-directional movement, including flexion, extension, adduction, abduction, internal rotation, and external rotation. The knee joint is formed by the lower end of the femur, the upper end of the tibia, and the patella. Its joint capsule is thinner, wider, and looser, reinforced by ligaments. The knee joint is primarily responsible for leg flexion and extension, bearing weight, and providing stability. Rehabilitation exercises for the hip joint include active ankle flexion and extension, isometric contraction exercises of the quadriceps and gluteal muscles, hip extension exercises, and active or active resisted hip flexion exercises in a semi-flexed position. Rehabilitation exercises for the knee joint include seated knee extension, strengthening exercises for the muscles surrounding the joint, and joint function training. These exercises aim to reduce pain, improve joint function, maintain joint range of motion, and slow disease progression.
