Show moreWe investigated the clinical and radiographic disease course of hand osteoarthritis as well as determinants of poor clinical outcome and radiographic progression over a period of six years in 289 patients with hand osteoarthritis. Because these patients had osteoarthritis at multiple joints this enabled us to not only assess the association between progression of osteoarhtiritis in different hand joints groups but also between progression of hand osteoarthritis and osteoarthritis change at the knee. In addition, genetic factors in hand osteoarthritis progression were investigated as well as the influence of illness perceptions. The hand osteoarthritis subsets erosive osteoarthritis and thumb base osteoarthritis are further characterised. In the last part of the thesis the clinimetric properties of a pain score for osteoarthritis and radiographic outcome measures for hand osteoarthritis are evaluated. Show less
