[Knee arthroplasty in osseous ankylosis. A case report]

We report on the successfully performed arthroplasty of a knee joint in a 19-year-old female patient in whom a bony ankylosis in malalignment had occurred following an infection. The deciding factor for performing the arthroplasty was not only the patients wish to regain mobility in the knee joint, but also the existing possibility of postoperative mobilization of the joint on a CPM-machine in combination with analgesia by means of a peridural catheter.
