Physical training in rehabilitation programs before and after total hip and knee arthroplasty

ObjectiveA review of the literature to investigate physical training in rehabilitation programs before and after hip and knee arthroplasty.MethodsWe performed a literature search of the MedLINE and Cochrane databases since 1966 to 2006 using 8 keywords for articles of literature reviews or randomized controlled trials investigating physical training before and after hip and knee arthroplasty.Results and DiscussionThe search resulted in 14 articles: 2 reviews of the literature and 7 articles of studies concerning total hip arthroplasty and 5 knee arthroplasty. Results were difficult to analyze because of the low number of patients included, a high number of dropouts, no matched control populations, different physical training protocols, and the use of functional scores or inadequate parameters. We found no randomized controlled trial concerning physical training after knee arthroplasty.ConclusionPhysical training does not seem benefit patients before hip or knee arthroplasty. However, the training may have benefit immediately after, and particularly well after, total hip arthroplasty.
