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 .

Continuous passive motion as an adjunct to active exercises in early rehabilitation following total knee arthroplasty – a randomized controlled trial
Purpose . Continuous passive motion is frequently used post-operatively to increase knee range of motion after total knee arthroplasty in spite of little conclusive evidence . The aim of this study was to examine whether continuous passive motion ( CPM ) as an adjunct to active exercises had any short time effects ( after one week and three months ) on pain , range of motion , timed walking and stair climbing . Method . A r and omized controlled trial was conducted . A total of 63 patients undergoing primary TKA were r and omly assigned into an experimental group receiving CPM and active exercises and a control group receiving active exercises only . Outcomes were assessed by goniometer , visual analogue scale ( VAS ) , timed ‘ Up and Go ’ test ( TUG ) , timed 40 m walking distance and timed stair climbing . Results . There were no statistical differences between the treatment groups for any outcome measures either at one week or after three months . For the whole group , a significant and 50 % reduction in pain score was found after three months ( p < 0.01 ) . Compared with before surgery , a significantly impaired knee flexion range of motion ( p < 0.01 ) and a significantly decreased number of patients able to climb stairs were found after three months ( p < 0.01 ) . Conclusion . CPM was not found to have an additional short-time effect compared with active physiotherapy . After three months considerable pain relief was obtained for the whole group , the patients preoperative ROM was not restored and the number of patients able to climb stairs had decreased
