Abstract
Falls among people with knee osteoarthritis (OA) can lead to hospitalization and reduced functional capacities. Understanding of risk factors for falls in the population could lead to an effective falls prevention intervention program, particularly in people with knee OA. This systematic review intended to review the factors associating with falls in people with knee OA. Searches were performed through the following electronic databases: CINAHL, MEDLINE, Web of Science, PubMed and the Cochrane Library. The electronic databases were searched, up until October 2017. The literature search reached 564 articles and four articles were finally selected according to the review’s inclusion criteria. The four articles included three prospective cohort studies and one cross-sectional study. Knee extension muscle strength (Crude OR = 0.3, 95% confidence interval [CI] 0.1-0.8), knee flexion muscle strength (Crude OR = 0.2, 95% confidence interval [CI] 0.0–1.0), knee pain (HR = 1.51, 95% confidence interval [CI] 1.32–1.72), use of bisphosphonates (OR = 1.32, 95% confidence interval [CI] 1.07–1.63) and falls in past 12 months (OR = 1.54, 95% confidence interval [CI] 1.35–1.77) were factors that most consistently associated with falls in people with knee OA.
