The knee CPM is designed to improve joint mobility and strength in the knee joint as well as in the hip joint. It has been found to be just as effective as part of a postoperative recovery plan as professional therapy; but at a significantly reduced cost.

A clinical study found that “CPM-treatment can especially be prolonged for outpatients; thus CPM-treatment can contribute to shorten the hospital stay and the time of treatment in general” Jaeger & Hassenpflug (1991).
