BACKGROUND: @entity1 with @entity626 ( @entity571 ) have a high prevalence of falls. Poor standing balance is one risk factor, but the extent of standing balance deficits in @entity1 with knee @entity571 is unknown. PURPOSE: The primary purpose of this study was to summarize available data on standing balance in @entity1 with knee @entity571 compared with @entity1 without knee @entity571 . A secondary purpose was to establish the extent of balance @entity66 severity. DATA SOURCES: A literature search of the MEDLINE, EMBASE, CINAHL, and Web of Science databases through November 19, 2014, was conducted. STUDY SELECTION: Studies on individuals with knee @entity571 containing clinical, quantifiable measures of standing balance were included. Methodological quality was assessed by 2 reviewers using a 16-item quality index developed for nonrandomized studies. Studies scoring >50% on the index were included. DATA EXTRACTION: @entity1 characteristics (age, sex, body mass index, @entity571 severity, compartment involvement, unilateral versus bilateral disease) and balance outcomes were extracted by 2 reviewers. Standardized mean differences were pooled using a random-effects model. DATA SYNTHESIS: The search yielded 2,716 articles; 8 met selection and quality assessment criteria. The median score on the quality index was 13/17. @entity1 with knee @entity571 consistently performed worse than healthy controls on the Step Test, Single-Leg Stance Test, Functional Reach Test, Tandem Stance Test, and Community Balance and Mobility Scale. The pooled standardized mean difference was -1.64 (95% confidence interval = -2.58, -0.69). No differences were observed between varying degrees of @entity893 , or between unilateral versus bilateral disease. LIMITATIONS: No studies compared between-knee @entity571 severities. Thus, expected changes in balance as the disease progresses remain unknown. CONCLUSIONS: Few studies compared @entity1 with knee @entity571 and healthy controls, but those that did showed that @entity1 with knee @entity571 performed significantly worse. More research is needed to understand the extent of @entity73 in @entity1 with knee @entity571 using easy-to-administer, clinically available tests.
