Hip resurfacing has been developed as a surgical alternative to total hip replacement (THR). The procedure consists of placing a cap (usually made of cobalt-chrome metal), which is hollow and shaped like a mushroom, over the head of the femur while a matching metal cup (similar to what is used with a THR) is placed in the acetabulum ( pelvis ...
A total hip replacement (total hip arthroplasty or THA) consists of replacing both the acetabulum and the femoral head while hemiarthroplasty generally only replaces the femoral head. Hip replacement is one of the most common orthopaedic operations, though patient satisfaction varies widely.
Conventional hip resurfacing today. Conventional hip resurfacing techniques were created as an alternative to total hip replacement, whereby only the diseased cartilage and a small surrounding area of the femur are removed, to be replaced with new surfaces. [1]
Hip resurfacing, sometimes called hip shaving, is preferred over a total hip replacement for elite athletes, Su said, because it preserves more of the femur, uses a metal alloy made of...
Hip resurfacing is a bone-conserving, less invasive alternative to total hip replacement (THR) for young patients, [3] markedly improves the health-related quality of life measures [4] and currently makes up around a twentieth of all hip arthroplasty (artificial joint) procedures performed in the United Kingdom.

Hip replacement can be performed as a total replacement or a hemi (half) replacement. A total hip replacement consists of replacing both the acetabulum and the femoral head while hemiarthroplasty generally only replaces the femoral head.
Hip replacement is a surgical procedure performed in dogs and cats as a salvage procedure, to alleviate severe pain in the hip due to, for example, hip dysplasia or irreparable bone fracture. [1] [2] The procedure replaces the head of the femur and the acetabulum with prosthetic implants. [1]
Knee replacement. Knee replacement, also known as knee arthroplasty, is a surgical procedure to replace the weight-bearing surfaces of the knee joint to relieve pain and disability, most commonly offered when joint pain is not diminished by conservative sources.
The modern total hip replacement was pioneered by Sir John Charnley, expert in tribology at Wrightington Hospital, in England in the 1960s. [10] He found that joint surfaces could be replaced by implants cemented to the bone.
Five-year clinical data, from several centers, are now available demonstrating their superiority relative to conventional UHMWPE for total hip replacement (see arthroplasty ). [24]
