Continuous passive motion following partial ankle joint arthroplasty.

Retrospective preliminary report of 19 cases undergoing partial ankle joint arthroplasties with open surgical procedures were rehabilitated with continuous passive motion (CPM). Preoperative and post-operative ankle range of motion and subjective findings (pain, physical signs, activity, quality of motion) were evaluated. Results indicated significant increases to ankle joint range of motion with the use of continuous passive motion, decreased pain, increased activity, decreased edema, and improved quality of motion in the majority of patients undergoing ankle joint arthroplasty with continuous passive motion.
