Arthrosis is excessive wear of joints beyond the usual age-related degeneration. For this reason, about 150,000 Germans are provided with an artificial knee joint every year. Early diagnosis and corresponding therapies could delay or even help to avoid these operations. Joints, however, degrade slowly over several years before causing pain and prompting the persons affected to see a doctor. In cooperation with the Sana Gelenk- und Rheumazentrum (Center for Degenerative Joint and Rheumatic Diseases), Bad Wildbad, researchers of Karlsruhe Institute of Technology (KIT) are presently working on a system that detects first indications of arthrosis based on changed motion patterns.
