Use of Inpatient Continuous Passive Motion Versus No CPM in Computer‐Assisted Total Knee Arthroplasty
BACKGROUND Continuous passive motion ( CPM ) has shown positive effects on tissue healing , edema , hemarthrosis , and joint function ( L. Brosseau et al. , 2004 ) . CPM has also been shown to increase short-term early flexion and decrease length of stay ( LOS ) ( L. Brosseau et al. , 2004 ; C. M. Chiarello , C. M. S. Gundersen , & T. O'Halloran , 2004 ) . The benefits of CPM for the population of patients undergoing computer-assisted total knee arthroplasty ( TKA ) have not been examined . PURPOSE The primary objective of this study was to determine whether the use of CPM following computer-assisted TKA result ed in differences in range of motion , edema/drainage , functional ability , and pain . METHODS This was an experimental , prospect i ve , r and omized study of patients undergoing unilateral , computer-assisted TKA . The experimental group received CPM thrice daily and physical therapy ( PT ) twice daily during their hospitalization . The control group received PT twice daily and no CPM during the hospital stay . Both groups received PT after discharge . Measurement included Knee Society scores , Western Ontario McMaster Osteoarthritis Index values , range of motion , knee circumference , and HemoVac drainage . Data were collected at various intervals from preoperatively through 3 months . RESULTS Although the control group was found to be higher functioning preoperatively , there was no statistically significant difference in flexion , edema or drainage , function , or pain between groups through the 3-month study period
