What is Continuous Passive Motion or CPM?

Continuous Passive Motion
or CPM is commonly used by orthopedic surgeons to aid in patient recovery following injury or surgery to the joint. After a surgery, many patients will experience pain which can lead to a tendency to not move the joint adequately enough to regain proper range of motion. This tissue around the joint will become stiff due to this lack of motion and scarring will begin to develop.

When a Continuous Passive Motion machine is applied after surgery, the joint can be moved through a range of motion for an extended periods of time. This use can significantly reduce the recovery time by increasing the range of motion, promote healing of the joint surfaces and soft tissues, reduce the development of adhesions and scar tissue, and decrease stiffness of the joint.  Studies have shown that patients using CPM therapy devices require less pain medication than patients who have had the same type of surgery and are not using Continuous Passive Motion in their rehabilitation.

Continuous Passive Motion devices are available for both upper and lower extremities and your physician will prescribe how the device is to be used in regard to rate of speed of motion, duration of use of the equipment and the rate of increase in degrees of motion, commonly referred to as "Flexion" and "Extension" in cases of the knee joint.

As an example, physicians will typically prescribe Continuous Passive Motion Therapy following these types of lower extremity surgeries and procedures.

The knee joint is formed by the tibia or "shin bone" and the femur or "thigh bone."  The joint ends are covered with a smooth layer of articular cartilage which allows the joint to move freely without pain in normal, healthy knee joints.  The knee joint is also enclosed in fibrous tissue which forms a capsule with a lining known as synovium.  The synovium produces a fluid which acts as a natural lubricant that reduces friction in the knee joint.  This friction is the action that produces the wear and tear on the knee joint.  In the cases where a total knee replacement may be required, the joint surfaces have been worn away and the knee is failing to function normally.

A total knee replacement procedure involves the replacement of the knee joint with an artificial joint or prosthesis.  The damaged ends of the bones and cartilage are replaced with metal and plastic surfaces that are designed to restore the knee movement lost by the original knee joint.  When a total knee replacement is performed, joint surfaces are removed from the end of the femur and tibia and instruments are used to create the exact surfaces necessary to accommodate the new artificial joint.  Once these surfaces are prepared, metal and plastic implants are placed and fitted.  The type of implant used in the procedure will depend upon the preference of the surgeon and the condition of the bone.
