The hip joint is a “ball and socket” joint. The “ball” is known anatomically as the femoral head. The “socket” is part of the pelvis known as the acetabulum. Both the femoral head and the acetabulum are coated with articular cartilage. The hip is one of the most stable and largest joints in the body. However, because hips bear your body weight, it is more likely to develop arthritis because of the extra pressure. Pain in the hip may be caused by injury to muscles,tendons or the small fluid-filled sacs (bursae) that cushion and lubricate joints.
Hip replacement (total hip arthroplasty) is surgery to replace a worn-out or damaged hip joint. The surgeon replaces the old joint with an artificial joint (prosthesis). This surgery may be a choice after a hip fracture or for severe pain because of arthritis.
Hip replacement surgery uses Implants made from metal, high density polyethylene or ceramic to replace a diseased or worn-out portions of the hip joint with prostheses (implants).
Hip revision surgery is performed to repair an artificial hip joint (prosthesis) that has been damaged over time, usually due to normal wear and tear of the prosthetic hip or sometimes due to infection. Revision surgery helps to correct the problem so the hip can function normally again.
