Repetitive static positions involving the knee joint might induce overuse and clinical symptoms related to osteoarthritis. This study evaluated extent and distribution of focal cartilage deformation of the knee after performing different frequently used positions in craftsman professions. Results indicate that HR-3D-MR-volumetry enables comprehension of significant change of cartilage deformation within the different cartilage plates. Also data provide references for contact zones and focal loading in various activities as well as information about reversibility of stress induced changes. Consideration of these findings may facilitate development of future preventive measures for labor protection, cartilage therapy as well as cartilage graft engineering.
