What is CPM?
CPM which stands for continuous passive motion, is a device that is used to gently flex and extend the knee joint. The CPM machine can be used after surgery to allow the knee joint to slowly bend. The initial thought was that CPM would improve motion following knee replacement surgery, as well as other knee procedures, and eliminate the problem of stiffness. CPM is a proven modality used to reduce pain and edema (swelling), increase/maintain range of motion, help prevent adhesions, contractures (muscle/joint stiffness) and DVTs (blood clots in veins that can block blood flow), minimize hospital stays and improves home Physical Therapy visits. CPM works in conjunction with Physical Therapy to have more productive therapy visits. Continuous passive motion also promotes faster and more productive cartilage and soft tissue healing.
By placing the knee in this device soon after surgery, scar tissue would not develop, and the problem of stiffness would not be a concern.
For many years, CPM machines were seen as a significant medical advancement that could help prevent postoperative complications from knee surgery. By getting the knee joint bending immediately following surgery, the goal was to improve restoration of mobility, and ultimately to speed recovery. CPM machines were used routinely after a number of different surgical procedures, particularly knee replacement surgery.
Stiffness after knee replacement can be a serious complication, and is one of the more common reasons why people are dissatisfied with knee replacement surgery. While approximately 90% of people are satisfied with the results of knee replacement, there are complications that can occur, and reasons why people are not happy with the results of their surgical procedure.
One of those problems that can occur his stiffness of the knee joint.
Understanding CPM Therapy
Your joints are designed to move. When they don’t move, they become stiff. More than likely, you’ve experienced knee joint stiffness after a long flight or a long ride in the car. After surgery, a knee that has been repaired stiffens up from the trauma that it has experienced. Extra fluid pools around the joint to protect it. This extra fluid increases swelling. The swelling then increases pain.
If a joint remains immobile, circulation is inhibited which can cause adhesions and scar tissue. As a result, a patient may experience complications and need to return to the hospital for additional procedures.
In order to combat this stiffness and to help decrease swelling and lessen pain, Continuous Passive Motion (CPM) therapy was developed – a clinically proven therapy that gets patients out of the hospital and back on their feet more quickly.
By slowly and rhythmically bending the knee without activating leg muscles, CPM therapy encourages circulation. This circulation lubricates the repaired joint and helps to flush out the extra fluid that has built up. This additional circulation has the added benefit of helping to deliver more nutrients to the repair which also helps to regenerate cartilage.
General CPM Coverage
Medicare and Medicaid cover CPM for total knee replacements and revisions only within 48 hours of surgery and allows for 21 days following surgery date. All other insurances cover CPM for total knee replacements with 21 days being the general timeframe. However, some insurances will cover CPM longer. A few insurances have stopped covering CPM for ACL surgeries altogether, we can discuss options available if that arises. If a CPM is not covered by insurance for any particular reason, we do all we can to work with the patient to have it NOT be a financial burden and to help in their recovery. If you have any questions about your current insurance coverage guidelines, please don’t hesitate to contact us!
