Changing clinician beliefs and behaviour in response to credible evidence of lack of treatment efficacy remains highly challenging
Arthroscopy is commonly used to treat people with knee pain due to osteoarthritis. However, data collected from randomised controlled trials over the past two decades have provided compelling evidence that, in general, arthroscopic treatment comprising debridement and lavage is no more effective than placebo surgery or non-operative alternatives,1,2 and observational data suggest that it may mean a joint replacement is needed sooner.3
