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 .

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 .

Prospective Randomized Clinical Trial of Continuous Passive Motion After Total Knee Arthroplasty
The authors report the results of a prospect i ve r and omized clinical trial using continuous passive motion after total knee arthroplasty . One hundred twenty patients were assigned r and omly to one treatment group : No continuous passive motion ( Group I ) , continuous passive motion from 0 ° to 50 ° and increased as tolerated ( Group II ) , and continuous passive motion from 70 ° to 110 ° ( Group III ) . The continuous passive motion was initiated in the recovery room and was maintained for a maximum of 24 hours at which point all patients began identical postoperative physiotherapy regimens . Patients were assessed preoperatively , during their hospital stay , at 6 weeks , 12 weeks , 26 weeks , and 52 weeks after their surgery . There were no statistical differences between any of the treatment groups regarding cumulative analgesic requirements , range of motion at any measured interval , length of stay ( Group I , 5.1 days ; Group II , 5.2 days ; Group III , 5 days ) or Knee Society scores . The current study does not support the use of short-term continuous passive motion after total knee replacement . A st and ard and a high flexion continuous passive motion protocol failed to show any advantage over physiotherapy alone in the parameters evaluated
