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 .

Squatting Following Total Knee Arthroplasty
& NA ; This prospect i ve study was performed to investigate whether postoperative alternate flexion and extension splinting ( daily change in position of immobilization by splinting ) was useful in restoring full range of motion ( ROM )  after total knee arthroplasty as compared with continuous passive motion . The  alternate flexion and extension splinting group and the  continuous passive motion group were each composed of 34 knees .  Final ROM was measured at an average of 3.5 years postoperatively . Squatting was possible in 31 knees ( 45.6 % ) of the alternate flexion and extension  splinting group . The postoperative ROM of the osteoarthritic knees ( 131.8 ° ± 12.3 ° ) was significantly greater than that of the rheumatoid knees ( 121.9 ° ± 22.4 ° ) ( p < 0.05 ) . The postoperative ROM of the alternate flexion and extension splinting group ( 135.1 ° ± 11.9 ° ) also was significantly greater than that of the continuous passive motion group ( 120.0 ° ± 19.7 ° ) ( p < 0.01 ) . There was no statistically significant relationship between the posterior slope of tibial cutting and the postoperative ROM . It is suggested that alternate flexion and extension splinting is effective in restoring full ROM after total knee arthroplasty
