No effect of continuous passive motion after arthroplasty of the knee

Abstract

We randomly allocated 54 patients to active physical therapy only or this combined with 2 hours of passive knee motion twice daily from 2-12 days after total knee arthroplasty. the range of knee motion was measured on the 14th postoperative day. We found no difference between the groups. We concluded that 4 hours' passive motion daily in addition to early, active physical therapy does not improve the range of knee motion or promote mobilization after arthroplasty. © 1988 Informa UK Ltd All rights reserved: reproduction in whole or part not permitted.
