To compare the sensitivity of WOMAC and the two added dimensions Sport and Recreation Function and Knee Related Quality of Life in subjects with radiographic knee OA to that in controls. To study the influence of age on the reported outcomes.
Outcomes were compared between subjects having had meniscectomy 21 years ago and which at time of follow-up had definite radiographic OA ( N=41, mean age 57), and age- and sex-matched controls without radiographic OA ( N=50, mean age 53). For the purpose of studying the impact of age, the groups were divided in two age groups, younger and older than 50 years, respectively. Close to 50% of both groups reported current physical activity levels of at least recreational golf, dancing, hiking, etc.
