Knee

The knee joint joins the thigh with the leg and consists of two articulations: one between the femur and tibia, and one between the femur and patella.

Since in humans the knee supports nearly the entire weight of the body, it is the joint most vulnerable both to acute injury and the development of osteoarthritis.
