The purpose of the study was to investigate the effect of continuous passive motion (CPM) after arthroscopy. A CPM machine was used one hour following knee surgery. Statistical analysis was performed to determine differences in knee range of motion (ROM), strength and circumference, at time intervals preoperatively, one, seven, and twenty-eight days following surgery. The analysis of variance revealed no significant difference between the CPM and control groups for any parameter. A significant interaction effect between treatment and time was demonstrated one day after surgery for extension, joint line circumference, and midthigh circumference; and 28 days after surgery for the latter. Based on the results of this study, CPM decreased joint line and mid-thigh edema with resultant increased extension one day after knee arthroscopy. CPM had no effect on postoperative days 7 and 28. CPM did not influence strength, but may have prevented decreased mid-thigh girth, 28 days postoperatively.
