CPM also called 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. 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. Knee surgery has come a long way in the past 50 years, and orthopedic surgeons are always looking into ways to improve their results. One persistent problem following joint surgery is stiffness of the joint. 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.

The continuous passive motion, or CPM, was developed in an effort to begin motion as soon as possible following surgery, and, hopefully, alleviate the problem of postoperative stiffness.

Several recent studies have investigated the use of the CPM following knee replacement surgery and ACL reconstruction surgery. In several studies the results are essentially the same—there is some benefit in the first days and weeks following surgery, but there is no difference in the overall outcome of the surgery.

The argument for a CPM is that patients do have an initial increase in motion following surgery that is more rapid than patients who do not use a CPM. Also, patients often feel a strong desire to be "doing something" to help their recovery. While CPM may not actually alter the result of the surgery, it can give patients a sense that they are doing something to help their recovery, even when resting in bed.

There are some specific procedures, such as a release of contracture or adhesions, where a CPM can be an important part of the recovery from knee surgery.

A study found that use of CPM after arthroscopic surgery to correct hip impingement was associated with improved hip flexion post-surgery. A study compared the benefits of CPM and physiotherapy for people with diabetes undergoing surgery for adhesive capsulitis, also known as frozen shoulder.

The researchers found that both CPM and traditional physiotherapy led to improved recovery at 12 weeks. However, patients that used CPM had more distinct improvement in pain levels and function.

Physical therapy and CPM are two common treatment options after elbow surgery. However, current evidence suggests that the use of CPM may be redundant and often ineffective. A small study found that adding CPM to a traditional rehabilitation program for wrist fractures offered no additional benefit. CPM machines may help treat chronic non-specific back pain. A small study examined the potential benefits of 3 weeks of self-administered CPM on a group of 36 people with mild to moderate non-specific chronic back pain.

The researchers found that patients who used the CPM machine for 10 minutes one to three times per day reported less pain at the end of the 3 weeks. Confirm with your doctor that a CPM machine is right for you, and ask about alternative treatments.

Recent research does not support their effectiveness in all situations. Most often, the device is used while lying in bed or on another comfortable surface. Usually, the machine comes with a remote control that lets you set the extension and flexion limits as well as the speed.

You can start or stop the machine by using the remote. There will likely be a number of knobs and straps on the machine that allow you to fit the machine to the length of your arm or leg.

Your healthcare provider can show you how to best adjust the device. The amount of time you should use your CPM machine depends on the type and extent of your surgery.

Typically, CPM machines are used for 4 hours per day for 4 weeks after hip surgery. A typical timeframe after a knee replacement is 3 weeks but can be shorter or longer. Some doctors still recommend the use of CPM machines, though many recent studies have questioned their effectiveness.
