The effects of knee arthroplasty on walking speed: a meta-analysis

BMC Musculoskeletal Disorders, 05/11/2012

This meta–analysis revealed a large effect of arthroplasty on walking speed 6–60 months post–operatively. For the first 0.5–5 months, heterogeneity of effect–sizes precluded a valid estimate of short–term effects. Hence, patients may expect a considerable improvement of their walking speed, which, however, may take several months to occur. Meta–regression analysis suggested a small decline from 13 months post–operatively onwards.
