The hip is one of the largest weight-bearing joints in the body. When it's working properly, it lets you walk, sit, bend, and turn without pain. Unlike the shoulder, the hip sacrifices degree of movement for additional stability. To keep it moving smoothly, a complex network of bones, cartilage, muscles, ligaments, and tendons must all work in harmony.
The hip is a ball-and-socket joint where the head of the femur articulates with the cuplike acetabulum of the pelvic bone. The acetabulum fits tightly around the head of the femur. The ball is normally held in the socket by very powerful ligaments that form a complete sleeve around the joint (the joint capsule). The capsule has a delicate lining (the synovium). The head of the femur is covered with a layer of smooth cartilage which is a fairly soft, white substance. The socket is also lined with cartilage. This cartilage cushions the joint, and allows the bones to move on each other with very little friction.
An x-ray of the hip joint usually shows a "space" between the ball and the socket because the cartilage does not show up on x-rays. In the normal hip this "joint space" is approximately 1/4 inch wide and fairly even in outline.

Direct Anterior Approach Hip Replacement
Direct Anterior Hip Replacement is a technique in which hip replacement surgery is performed through an alternative approach compared to conventional hip replacement surgery. Historically, hip replacement surgery was performed utilizing traditional posterior or lateral approaches. This necessitates that certain muscles or tendons are cut in order to access the hip joint and perform the surgery.
Hip arthroscopy is a relatively new surgical technique that can be effectively employed to treat a variety of hip conditions.

Femoro Acetabular Impingement FAI
Femoroacetabular Impingement FAI is a condition resulting from abnormal pressure and friction between the ball and socket of the hip joint resulting in pain and progressive hip dysfunction. This when left untreated leads to the development of secondary osteoarthritis of the hip.
Total Hip Replacement (THR)
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.

Revision Hip Replacement
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.
