CONTINUOUS PASSIVE MOTION IMPROVES ACTIVE KNEE FLEXION AND SHORTENS HOSPITAL STAY BUT DOES NOT AFFECT OTHER FUNCTIONAL OUTCOMES AFTER KNEE ARTHROPLASTY.

This article cites a study assessing the effectiveness of continuous passive motion (CPM) after total knee arthroplasty (TKA). Data sources for the presents study were various previous studies that were identified by searching MEDLINE, EMBASE/Excerpta Medica, HealthSTAR, Sports Discus, CINAHL, the Cochrane Controlled Trials Register, and other information sources. The quality of each study was assessed with use of the 5-point Jadad scale. Data related to active and passive knee range of motion, length of hospital stay, pain, and quadriceps strength were gathered and compared. Based on findings of the study, it was concluded that CPM imporves active knee flexion and shortens hospital stay but does not affect other functional outcomes after TKA.
