Revision knee replacement

Revision knee replacement

TKRs have excellent long-term survival, with 82% lasting over 20 years and over 95% lasting 10–15 years. In the first few years, revision surgery is most likely to be due to infection, and non-infective causes, such as instability and malalign ment. Beyond 10 years, revision is usually a result of aseptic Jean Martin Charcot , 1825–1893, physician, La Salpêtrière, Paris, France. - loosening of components, which is often a result of wear of the plastic insert and polyethylene-induced osteolysis. With any failed joint replacement, infection should be excluded as this can compromise the result of surgery and may require a di ff erent surgical strategy , e.g. a two-stage rather than a single- stage procedure. Revision arthroplasty is technically more challenging, requires more complex and expensive implants and has a higher complication rate. When done for the correct indication, results are very good. As with a primary TKR, the goal remains to provide a well-aligned, stable and pain-free knee ( Figure 40.6 ).
