OBJECTIVE: To describe the cross-sectional and longitudinal associations between knee regional @entity1143 and knee @entity158 in older adults. METHODS: Data from a population-based random sample (n = 880, mean age 62 yrs, 50% @entity1 ) were used. Baseline @entity1143 was graded (0-3) using T2-weighted magnetic resonance imaging (MRI) in the suprapatellar pouch, central portion, posterior femoral recess, and subpopliteal recess. @entity1143 of the whole joint was defined as a score of >=  2 in any subregion. Other knee structural (including cartilage, bone marrow, and menisci) lesions were assessed by MRI at baseline. Knee @entity158 was assessed by the Western Ontario and McMaster Universities @entity571 Index questionnaire at baseline and 2.6 years later. Multivariable analyses were performed after adjustment for age, sex, body mass index, and other structural lesions. RESULTS: The prevalence of @entity1143 was 67%. Suprapatellar pouch @entity1143 was significantly and independently associated with increased total and nonweight-bearing knee @entity158 in both cross-sectional and longitudinal analyses (for an increase in total knee @entity158 of >=  5, @entity4736 .26 per grade, 95% CI 1.04-1.52), and increased weight-bearing knee @entity158 in longitudinal analysis only. @entity1143 in posterior femoral recess and central portion were independently associated with increases in nonweight-bearing @entity158 ( @entity4736 .63 per grade, 95% CI 1.32-2.01 and @entity4736 .29 per grade, 95% CI 1.01-1.65, respectively) in longitudinal analyses only. CONCLUSION: Knee joint @entity1143 has independent associations with knee @entity158 in older adults. Suprapatellar pouch @entity1143 is associated with nonweight-bearing and weight-bearing knee @entity158 , while posterior femoral recess and central portion @entity1143 are only associated with nonweight-bearing @entity158 .
