Following arthroplasty, also known as total knee replacement surgery, having a continuous passive motion machine at home is necessary. Using a continuous passive motion facilitates recovery after knee surgery comparably to attending professional physical therapy sessions, states the National Center for Biotechnology Information.
Recovery following arthroplasty is a process that includes rehabilitation. The physician prescribes medication to help with the pain, and the patient begins an agreed-upon treatment regimen including physical therapy and a continuous passive motion machine. Physical therapy takes place at a facility, but using a continuous passive motion at home improves the range of motion of the knee.
Progress is reported as a knee score, which includes points for the level of pain, stability and the range of motion of the knee. Regularly bending and extending the leg keep the knee active and fight flexion contracture. Using the continuous passive motion machine at home costs the patient less than attending physical therapy sessions at a facility, according to the National Center for Biotechnology Information.
In a randomized study reported by the National Center for Biotechnology Information, using the continuous passive motion at home gave similar results as using a professional physical therapist at a facility. The study measured the improvement in the range of motion in the knee of a group of patients who used only the continuous passive motion machine and compared those to a group who used only physical therapy sessions for recovery. The results were comparable for almost half the cost.
