Continuous Passive Motion (CPM) is a postoperative treatment method that is designed to aid recovery after joint surgery. In most patients after extensive joint surgery, attempts at joint motion cause pain and as a result, the patientfails to move the joint. This allows the tissue around the joint to become stiff and for scar tissue to form resulting in a joint which has limited range of motion and often may take months of physical therapy to recovery that motion.Passive range of motion means that the joint is moved without the patient's muscles being used. Continuous Passive Motion devices are machines that have been developed for patients to use after surgery.

Applied postoperatively, this device may be used on an inpatient or an outpatient basis. By using a motorized device to very gradually move the joint, it is possible to significantly accelerate recovery time by decreasing soft tissue stiffness,increasing range of motion, promoting healing of joint surfaces and soft tissue, and preventing the development of motion-limiting adhesions (scar tissue). Interestingly, this is accomplished without patient effort (passively) as the machine moves ajoint through a defined (prescribed) range of motion for an extended period of time. Even more surprisingly, studies have shown that patients using CPM devices require less pain medication then patients who have had the same type of surgery and are notusing this device.CPM may be prescribed by orthopaedic surgeons following total knee replacement, anterior cruciate ligament reconstruction, tendon repair, joint manipulation under anesthesia, arthroscopic debridement of adhesions, open reduction and internal fixation (stabilization) of intra-articular fractures, rotator cuff repair, articular cartilage microfracture, and articular cartilage transplantation).. There are CPM devices for the knee, ankle, shoulder, elbow, wrist, and hand.The physician prescribes how the CPM unit should be used by the patient (speed, duration of usage, amount of motion, rate of increase of motion, etc.).
