Understanding Hip Anatomy

Discover how your hip works

A joint is a point where multiple bones meet and work together so that you can perform daily tasks like sit, climb stairs, walk comfortably, etc. The hip joint is described as being a “ball and socket” joint due to the joint’s appearance of a ball (femoral head) fitting snugly in a cup-like socket (acetabulum). The ball (femoral head) is located at the top of the thigh bone (femur) and the socket (acetabulum) is part of the pelvis. The area where the bones meet is covered by a slick but firm tissue called cartilage, allowing the joint to move smoothly.

As joint disease progresses, the bones begin to rub together causing a rough misshapen surface, sometimes resulting in bone-on-bone contact, producing pain and stiffness.

A detailed image depicting an osteoarthritic hip that shows as hip joint disease progresses the surrounding bones begin to rub together which can result in bone-on-bone contact that will inevitably cause severe pain and stiffness in the hip joint.

Hip replacement surgery replaces the worn and arthritic areas of your hip joint and replaces those areas with an implant that helps restore a smooth joint surface.

The hip replacement component is used to replace the worn and arthritic areas of your hip joint to restore a smooth joint surface which should directly result in the reduction of hip joint pain and stiffness.

IMPORTANT SAFETY INFORMATION

As with any medical treatment, individual results may vary. The performance of hip replacements depends on age, weight, activity level and other factors. There are potential risks and recovery takes time. If you have conditions that limit rehabilitation you should not have this surgery. Only an orthopaedic surgeon can tell you if hip replacement is right for you.
