The knee at times may not recover its normal range of motion (0–135 degrees usually) after total knee replacement. Much of this is dependent on pre-operative function. Most patients can achieve 0–110 degrees, but stiffness of the joint can occur.
UKA surgery may reduce post-operative pain and have a shorter recovery period than a total knee replacement procedure, particularly in people over 75 years of age. Moreover, UKAs may require a smaller incision , less tissue damage, and faster recovery times.
One cell-based replacement technique is called autologous chondrocyte implantation (ACI) or autologous chondrocyte transplantation (ACT). A review evaluating autologous chondrocyte implantation was published in 2010. The conclusions are that it is an effective treatment for full thickness chondral defects.

As well as the standard total knee replacement surgery, the unicompartmental knee replacement, in which only one weight-bearing surface of an arthritic knee is replaced, may be performed, but it bears a significant risk of revision surgery. Joint replacements are used for other joints, most commonly the hip or shoulder.
Depending on the joint involved and the pre-op status of the person, the time of hospitalization varies from 1 day to 2 weeks, with the average being 4–7 days in most regions. [ citation needed ] Physiotherapy is used extensively to help people recover function after joint replacement surgery.
Two and a half years later, Roker had knee replacement surgery. The surgery on his right knee took just over an hour.
Arthroplasty (literally " [re-]forming of joint ") is an orthopedic surgical procedure where the articular surface of a musculoskeletal joint is replaced, remodeled, or realigned by osteotomy or some other procedure.
It appears that the ideal period for applying manipulation to knee stiffness after TKA is at less than 20 weeks from primary surgery, with no added benefit reported from re-manipulations.
Because prosthetic knees may wear out over time, an osteotomy procedure can enable younger, active osteoarthritis patients to continue using the healthy portion of their knee. The procedure can delay the need for a total knee replacement for up to ten years.
