Continuous passive motion compared with intermittent mobilization after total knee arthroplasty. Elaboration of French clinical practice guidelines

ObjectiveTo develop clinical practice guidelines concerning the use of continuous passive motion (CPM) compared with intermittent mobilization after total knee arthroplasty (TKA).MethodWe used the SOFMER (French Physical Medicine and Rehabilitation Society) methodology, combining systematic literature review and collection of everyday clinical practice concerning postoperative rehabilitation techniques and external review by a multidisciplinary expert panel, to develop the guidelines.ResultsThe literature contains no evidence of the advantages of CPM over other techniques of mobilization, although CPM could be adjuvant therapy used to accelerate short-term recovery. However, in France, CPM remains widely used after TKA, both in orthopedic surgery units and in physical medicine and rehabilitation services.ConclusionGood methodological quality studies are needed to assess different CPM modalities and compare them to alternative intermittent mobilization techniques, particularly those with therapy starting from a flexed position.
