The estimates for risk of manipulation and adverse events are very imprecise and the estimate for the risk of adverse events does not distinguish between a clinical ly important increase and decrease in risk .
There was insufficient evidence to determine the effect of CPM on participants ' global assessment of treatment effectiveness .
CPM does not have clinical ly important effects on active knee flexion ROM , pain , function or quality of life to justify its routine use .
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 .
This review is an up date of a 2003 and 2010 version of the same review .
A comparison of 2 continuous passive motion protocols after total knee arthroplasty: a controlled and randomized study.
Effect of continuous passive motion ( CPM ) protocol s on outcomes after total knee arthroplasty . In this prospect i ve r and omized controlled study , 147 patients were assigned to 1 of 3 treatment groups : CPM from 0 degrees to 40 degrees and increased by 10 degrees per day , CPM from 90 degrees to 50 degrees ( early flexion ) and gradually progressed into full extension over a 3-day period , and a no-CPM group . The CPM was administered twice a day for 3 hours over a 5-day period . All patients participated in the same postoperative physiotherapy program . Patients were assessed preoperatively , day 5 , 3 months , and 1 year postoperatively . The early flexion group had significantly more range of flexion than both the st and ard and control groups at day 5 . There was no significant difference between the groups for any other variable tested at any time frame . Key words : total knee arthroplasty , CPM , rehabilitation , outcomes
