Previously, a popular form of arthroplasty was '''interpositional arthroplasty''' with interposition of some other [[biological tissue|tissue]] like [[skin]], [[muscle]] or [[tendon]] to keep [[Inflammation|inflammatory]] surfaces apart or '''excisional arthroplasty''' in which the joint surface and bone was removed leaving [[scar]] tissue to fill in the gap. Other forms of arthroplasty include '''resection(al) arthroplasty''', '''resurfacing arthroplasty''', '''mold arthroplasty''', '''cup arthroplasty''', '''silicone replacement arthroplasty''', etc. Osteotomy to restore or modify joint congruity is also an arthroplasty. For the last 45 years the most successful and common form of arthroplasty is the [[replacement_joint|surgical replacement]] of arthritic or destructive or [[Necrosis|necrotic]] joint or joint surface with [[prosthesis]]. For example a hip joint that is affected by osteoarthritis may be replaced entirely ([[Hip replacement|total hip arthroplasty]]) with a prosthetic hip. This would involve replacing both the acetabulum (hip socket) and the head and neck of the [[femur]]. The purpose of this procedure is to relieve pain, to restore range of motion and to improve walking ability, thus leading to the improvement of muscle strength. Indications for arthroplasty include: *[[osteoarthritis]] (OA) *[[rheumatoid arthritis]] (RA) *[[avascular necrosis]] (AVN) or osteonecrosis (ON) *congenital dislocation of the hip joint (CDH) [[Hip dysplasia (human)]] *acetabular dysplasia (shallow hip socket) *frozen shoulder, loose shoulder *traumatized and malaligned joint *joint stiffness {{Surgery-stub}} {{Operations and other procedures on the musculoskeletal system}} [[Category:Orthopedics]] [[fr:Arthroplastie]] [[hr:Artroplastika]] [[ro:Artroplastie]]
