Hip and Knee

The knee is the body's largest joint and one of the most vulnerable to injury. Bones, cartilage, ligaments, and tendons are the four primary structures. Bones. The thighbone (femur) and the shinbone connect to form the knee joint (tibia). The greater trochanter of the femur, or "thigh bone," is placed lateral and anterior to the gluteal region, inferior to the iliac crest, and overlaying the hip region. Three of the pelvic bones have merged into the hip bone, or acetabulum, which is part of the hip region in adults.

The hip joint is a ball and socket joint that connects the femur head to the acetabulum of the pelvis. The hip joint connects the axial skeleton to the lower extremities. The hip joint has three principal axes of movement, all of which are perpendicular to one another. In extension, the hip joint capsule is tight, while in flexion, it is more relaxed. The knee joint is one of the body's largest and most complicated joints. It is made up of four bones and a complex network of ligaments and muscles.
