Overall ranking 4
JLA question ID 0093/4

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?
