To determine the association between inflammatory markers and change in knee pain over 5 years. Methods: A total of 149 randomly selected subjects (mean 63 years, range 52-78; 46 female) was studied. Serum levels of high sensitivity C-reactive protein (hs-CRP), tumour necrosis factor alpha (TNF-a) and interleukin (IL)-6 were measured at baseline and 2.7 years later. Knee pain was recorded using the Western Ontario and McMasters osteoarthritis index questionnaire at baseline and 5 years later. Knee radiographic osteoarthritis of both knees was assessed at baseline, and knee bone marrow lesions, joint effusion and cartilage defects were determined using T1 or T2-weighted fat saturated MRI. Results: After adjustment for confounding variables, baseline hs-CRP was positively associated with change in total knee pain (-=0.33 per mg/l, p=0.032), as well as change in the pain at night in bed (-=0.12 per ml/ pg, p=0.010) and while sitting/lying (-=0.12 per ml/ pg, p=0.002). Change in hs-CRP was also associated with change in knee pain at night and when sitting/lying (both p
