Objective Knee osteoarthritis (OA) and pain are assumed to be barriers to meeting physical activity guidelines, but this has not been formally evaluated. The purpose of this study was to determine the proportions of people with and those without knee OA and knee pain who meet recommended physical activity levels through walking. Methods We performed a cross-sectional analysis of community-dwelling adults from the Multicenter Osteoarthritis Study who had or who were at high risk of knee OA. Participants wore a StepWatch activity monitor to record steps per day for 7 days. The proportion of participants who met the recommended physical activity levels was defined as those accumulating =150 minutes per week at =100 steps per minute in bouts lasting =10 minutes. These proportions were also determined for those with and those without knee OA, as classified by radiography and by severity of knee pain. Results Of the 1,788 study participants (mean +/- SD age 67.2 +/- 7.7 years, mean +/- SD body mass index 30.7 +/- 6.0 kg/m2, 60% women), lower overall percentages of participants with radiographic knee OA and knee pain met recommended physical activity levels. However, these differences were not statistically significant between those with and those without knee OA; 7.3% and 10.1% of men (P = 0.34) and 6.3% and 7.8% of women (P = 0.51), respectively, met recommended physical activity levels. Similarly, for those with moderate/severe knee pain and those with no knee pain, 12.9% and 10.9% of men (P = 0.74) and 6.7% and 11.0% of women (P = 0.40), respectively, met recommended physical activity levels. Conclusion Disease and pain have little impact on achieving recommended physical activity levels among people with or at high risk of knee OA.
