dc.description.abstractStudy Design: Systematic review with meta-analysis. Background: Lower-limb osteoarthritis (OA) is associated with pain and reduced function. Most research focuses on hip and knee OA- related impairments; consequently, impairments that characterize ankle OA are not well understood. Objective: To systematically review available evidence of physical impairments in individuals with ankle OA. Methods: A comprehensive search of electronic databases was conducted from their inception to July 2017. Studies were screened using predefined inclusion/exclusion criteria. Studies that compared physical measures (excluding gait) between individuals with ankle OA and healthy controls or the unaffected ankle were included. Two reviewers rated studies for quality. Meta-analyses with random effects were conducted when appropriate. Results: Of 4565 identified studies (563 participants), 8 satisfied the inclusion criteria and 3 studies were included in meta-analyses. All studies evaluated a range of impairments at end-stage OA, and exhibited poor reporting of missing data, assessor blinding, and measurement validity. Meta-analyses revealed large impairments of ankle sagittal plane motion and strength. Evidence from single studies indicated large deficits of ankle frontal plane motion and strength, talar translation and rotation on arthrometry, balance, and electromyography of ankle joint muscles. There were also abnormal bony alignments and greater fatty infiltrate in all calf muscle compartments. Conclusion: The results of this literature review suggest significant ankle motion, strength, and functional impairments in individuals with ankle OA. The strength of the conclusions is limited, due to the small number and methodological limitations of published studies. Level of Evidence: Symptom prevalence, level 1a.
