In a newly released study, 63% of female participants ages 50 and older reported persistent, incident or intermittent knee pain over a 12-year period starting in 1989. According to the U.K.-based study, which appeared in the Dec. 16, 2011, journal Arthritis & Rheumatism, predictors for persistent pain included higher body mass index, previous knee injury and radiographic osteoarthritis.
The team found 44% reported "any days of pain," while 23% reported "pain on most days of the previous month." Of the women experiencing "any pain" or "pain on most days," 9% and 2%, respectively, had persistent pain; 24% and 16% had incident pain; and 29% and 18% had intermittent pain. Researchers determined a higher BMI was a predictor of persistent and incident pain patterns, while radiographic OA predicted persistent pain. Participants who reported knee injury were likely to have persistent or intermittent pain patterns.
The authors' findings confirm the presence of variable pain patterns, with few women consistently reporting knee pain at each measurement time point. To view an article abstract, visit onlinelibrary.wiley.com/doi/10.1002/art.33434/abstract. •
