Low back pain (LBP) is a potential risk factor for falls in people with knee OA, but this issue has not been addressed adequately in previous studies. The objective of this study was to investigate the relationship between LBP and falls in people with knee OA in a 12\u2010month period.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Participants with knee OA (Kellgren\/Lawrence [K\/L] grade \u22651) completed questionnaires for LBP and falls that occurred in the preceding 12 months. Binary and ordinal logistic regression analyses were performed to assess the relationship between LBP or moderate\u2010to\u2010severe LBP (numeric rating scale \u22654 points) and any fall (\u22651 fall) or recurrent falls (\u22652 falls) after adjustment for age, sex, K\/L grade, knee pain severity, and quadriceps strength. Sensitivity analyses were performed excluding people with sciatica, nonchronic LBP, K\/L grade 1, and those receiving pain medications.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>We included 189 participants (ages 61\u201390 years, 78.3% women) in this study. Of these participants, 41 (21.6%) reported falls in the preceding 12 months. People with any LBP (n = 101) and those with moderate\u2010to\u2010severe LBP (n = 45) had 2.7\u2010 and 3.7\u2010times higher odds of recurrent falls, respectively.
