The hip joint is a true ball-and-socket joint. This arrangement gives the hip a large amount of motion needed for daily activities like walking, squatting, and stair-climbing.

​

Understanding how the different layers of the hip are built and connected can help you understand how the hip works, how it can be injured, and how challenging recovery can be when this joint is injured. The deepest layer of the hip includes the bones and the joints. The next layer is made up of the ligaments of the joint capsule. The tendons and the muscles come next.
