Device and Method for Determining at Least One Characteristic Point of Joint to be Orthopedically Measured

The invention relates to a device for determining at least one characteristic point of a joint which joins together two limbs and is to be measured orthopedically, said device comprising a first coupling element which may be positioned on a first limb adjoining the joint, a second coupling element which may be moved relative to the first coupling element and may be positioned on a second limb adjoining the joint, and a measuring device for determining the position of the first coupling element relative to the second coupling element. This device provides that the measuring device has at least one reference point rigidly connected to one of the first and second coupling elements, and also has a reference point detection device rigidly connected to the respective other of the first and second coupling elements, the reference point detection device detecting a plurality of positions of the reference point relative to the reference point detection device during a movement of the first and second limbs with respect to one another and determining therefrom the at least one characteristic point.
