Use of continuous passive motion after total knee arthroplasty.
Sixty primary total knee arthroplasties in 43 Chinese patients were included into a prospect i ve study . Twenty-six patients who had unilateral knee arthroplasty were r and omized to receive continuous passive motion ( CPM ) or immobilization in the first week . The 2 groups of patients were comparable in demographic data and preoperative knee range of motion ( ROM ) . In 17 patients who had 1-stage sequential bilateral arthroplasties , one side had CPM and the other side was immobilized . The active knee ROM was assessed regularly until 1 year after the operation . For all patients , the early active knee ROM in the CPM group was significantly better than the immobilization group . There was no difference after 7 days , however . For patients who had 1-stage bilateral total knee arthroplasties , the active knee ROM was significantly better on the CPM side until day 28 . After 4 weeks , there was no difference between the CPM group and the immobilization group . Immobilization after total knee arthroplasty does not preclude good ROM
