ABSTRACT
The pelvis, hip and knee (and ankle) form the basic structures involved in lower extremity mobility and stability. The considerable range of motion of the thigh and leg is achieved through the dynamic relationship between the pelvic girdle and hip joint and the knee joint. Structurally, movement is brought about by articulation of the pelvis and femur at the hip joint, and articulation of the femur and tibia at the knee joint. Functionally, movement is achieved via a multitude of one- and two-joint muscles that mobilise and stabilise these joints. The skeletal anatomy of the pelvis, hip and knee is shown in figure 12.1.
