Normal Anatomy of the hip joint
The thigh bone, femur, and the pelvis, acetabulum, join to form the hip joint. The hip joint is a “ball and socket” joint. The “ball” is the head of the femur, or thigh bone, and the “socket” is the cup shaped acetabulum.
The joint surface is covered by a smooth articular surface that allows pain free movement in the joint.
The cartilage cushions the joint and allows the bones to move on each other with smooth movements. This cartilage does not show up on X-ray, therefore you can see a “joint space” between the femoral head and acetabular socket.
The pelvis is a large, flattened, irregularly shaped bone, constricted in the center and expanded above and below. It consists of three parts: the ilium, ischium, and pubis.
The socket, acetabulum, is situated on the outer surface of the bone and joins to the head of the femur to form the hip joint.
The femur is the longest bone in the skeleton. It joins to the pelvis, acetabulum, to form the hip joint.

Hip arthroscopy is a relatively new surgical technique that can be effectively employed to treat a variety of hip conditions.

Femoroacetabular impingement (FAI) is a condition where there is too much friction in the hip joint from bony irregularities causing pain and decreased range of hip motion. The femoral head and acetabulum rub against each other creating damage and pain to the hip joint. The damage can occur to the articular cartilage (the smooth white surface of the ball or socket) or the labral tissue (the lining of the edge of the socket) during normal movement of the hip.
Total Hip Replacement (THR) procedure replaces all or part of the hip joint with an artificial device (prosthesis) to eliminate pain and restore joint movement.

Hip Resurfacing or bone conserving procedure replaces the acetabulum (hip socket) and resurfaces the femoral head. This means the femoral head has some or very little bone removed and replaced with the metal component. This spares the femoral canal. Find out more about Hip Resurfacing from the following options.

This maybe because part or all of your previous hip replacement needs to be revised. This operation varies from very minor adjustments to massive operations replacing significant amounts of bone and hence is difficult to describe in full.
