Abstract
The invention relates to a device for determining the stability of a knee joint. The device comprises includes a measuring sensor (14), which can be attached via a fastening device (16) to a lower leg (12) associated with the knee joint (11). The measuring sensor (14) is designed to measure an acceleration in at least one direction (z) during a movement of the lower leg (12). Furthermore, a processing device (18) is provided for processing measured values of the measuring sensor (14) in order to infer the stability of the knee joint (11) from the processed measured values.
