BACKGROUND Arthritis of the knee is a common problem causing pain and disability .
If severe , knee arthritis can be surgically managed with a total knee arthroplasty .
Rehabilitation following knee arthroplasty often includes continuous passive motion ( CPM ) .
CPM is applied by a machine that passively and repeatedly moves the knee through a specified range of motion ( ROM ) .
It is believed that CPM increases recovery of knee ROM and has other therapeutic benefits .
However , it is not clear whether CPM is effective .
OBJECTIVES To assess the benefits and harms of CPM and st and ard postoperative care versus similar postoperative care , with or without additional knee exercises , in people with knee arthroplasty .

Exercise combined with continuous passive motion or slider board therapy compared with exercise only: a randomized controlled trial of patients following total knee arthroplasty.
BACKGROUND AND PURPOSE The primary purpose of this r and omized controlled trial was to determine which method of mobilization - ( 1 ) st and ardized exercises ( SE ) and continuous passive motion ( CPM ) , ( 2 ) SE and slider board ( SB ) therapy , using an inexpensive , nontechnical device that requires minimal knee active range of motion ( ROM ) , or ( 3 ) SE alone-achieved the maximum degree of knee ROM in the fIrst 6 months following primary total knee arthroplasty ( TKA ) . The secondary purpose was to compare health-related quality of life among these 3 groups . SUBJECTS The subjects were 120 patients ( n=40/group ) who received a TEA at a teaching hospital between June 1997 and July 1998 and who agreed to participate in the study . METHODS Subjects were examined preoperatively , at discharge , and at 3 and 6 months after surgery . The examination consisted of measurement of knee ROM and completion of the Western Ontario and McMaster Universities ( WOMAC ) Osteoarthritis Index and the Medical Outcomes Study 36-Item Short-Form Health Survey ( SF-36 ) . RESULTS The 3 treatment groups were similar with respect to age , sex , and diagnosis at the start of the study . There were no differences in knee ROM or in WOMAC Osteoarthritis Index or SF-36 scores at any of the measurement intervals . The rate of postoperative complications also was not different among the groups . DISCUSSION AND CONCLUSION When postoperative rehabilitation regimens that focus on early mobilization of the patient are used , adjunct ROM therapies ( CPM and SB ) that are added to daily SE sessions are not required . Six months after TEA , patients attain a satisfactory level of knee ROM and function
