title: The efficacy of continuous passive motion after total knee arthroplasty: a comparison of three protocols.
abstract: We conducted a randomized, controlled trial to determine the efficacy of CPM following total knee arthroplasty (TKA). Postoperative outcomes of interest were: swelling, drop in hemoglobin, self-reported pain scores, range of motion, and hospital length of stay. A total of 160 subjects were randomized into one of three treatment groups: CPM device on and moving from the immediate post-operative period, CPM device on and stationary at 90 degree flexion for the first night and then moving throughout the rest of their stay, and no CPM (N = 55, 51, and 54, respectfully). Subjects were followed during the first and second postoperative day until their first follow-up appointment approximately 3-4 weeks post-operatively. Cost of CPM was further evaluated. CPM provided no benefit to patients recovering from TKA.
