Instructions for a Knee CPM Machine

Using a continuous passive motion, or CPM machine, after a knee injury or surgical procedure offers a convenient at-home physical therapy option. Health care providers commonly prescribe the use of a CPM machine to reduce swelling and to help cartilage and other tissues heal properly, with use of the machine typically directed the first weeks of rehabilitative therapy. The physician or physical therapist sets the range of motion parameters and adjustments are made as the knee heals. Rent a CPM machine from a medical supply store if the machine is not available from your health care provider.
