<unk> , also known as<unk>  arthroplasty, is a surgical procedure to replace the weight-bearing surfaces of the<unk>  joint to relieve pain and disability, most commonly offered when joint pain is not diminished by conservative sources and also for other<unk>  diseases such as rheumatoid arthritis and psoriatic arthritis. In patients with severe deformity from advanced rheumatoid arthritis, trauma, or long-standing osteoarthritis, the surgery may be more complicated and carry higher risk. Osteoporosis does not typically cause<unk>  pain, deformity, or inflammation and is not a reason to perform<unk> . Other major causes of debilitating pain include meniscus tears, cartilage defects, and ligament tears. Debilitating pain from osteoarthritis is much more common in the elderly.<unk>  surgery can be performed as a partial or a total<unk> . In general, the surgery consists of replacing the diseased or damaged joint surfaces of the<unk>  with metal and plastic components shaped to allow continued motion of the<unk> . The operation typically involves substantial postoperative pain and includes vigorous physical rehabilitation. The recovery period may be 12 weeks or longer and may involve the use of mobility aids (e.g. walking frames, canes, crutches) to enable the patient's return to preoperative mobility. It is estimated that approximately 82% of total<unk> s will last 25 years.
