Priority 4 from the Revision Knee Replacement PSP

UNCERTAINTY: What factors determine (predict) whether revision knee surgery is likely to work?   (JLA PSP Priority 4)
Overall ranking 4
JLA question ID 0093/4
Explanatory note Given increasing numbers of knee replacements and rising life expectancy, there is likely to be an increased burden for revision surgery in the future. However, patient selection is paramount, and both patients and healthcare professionals are eager explore ways to best predict which patients will indeed benefit from revision surgery, to help weigh up with the potential risks of surgery.

Health Research Classification System category Musculoskeletal
Extra information provided by this PSP
Original uncertainty examples How do outcomes of revision TKR depend on the indication. I suspect that a revision for frank loosening is more likely to be successful than for dubious diagnoses such as 'mid flexion instability'. ~  when should revision knee surgery be performed? to improve what problems after first replacement? ~ What are the outcomes of re-revision and re-re-revision? ~ What is the expected improvement in functional walking distance. ~ how successful is redo surgery?
