Cartilage
strain is discussed as potential cause for degeneration and osteoarthritis.
Dimension of global/regional cartilage deformation and its distribution in
knee cartilage after kneeling/squatting were evaluated. Detected small global
cartilage deformation laid within the magnitude of change after common daily
exercise/sports, consistent with biomechanical examinations. 3D-volumetry
enable anatomy- and individuum-specific analysis by detailed depiction of
regional deformation, while global parameters tend to average out local
changes leading to underestimation of changes. Data indicate areas of
deformation across the joint surface and might serve as a base for comparison
to degenerative changes in patients and for the development of biomechanical
models.
