Research: Effectiveness of Continuous Passive Motion and Conventional Physical Therapy After Total Knee Arthroplasty

What is a continuous passive motion machine?

Continuous passive motion (CPM) is a treatment method designed to aid in the recovery of joints immediately after trauma or surgery. CPM is carried out by a CPM device, which constantly moves the joint through a controlled range of motion, the exact range is dependent upon the joint, but in most cases the range of motion is increased over time.

a. Description and Symptoms of condition: Knee joint replacement is surgery to replace a painful damaged or diseased knee joint with an artificial joint. The orthopedic surgeon makes a cut over the affected knee. The knee cap (patella) is moved out of the way, and the ends of the thigh bone (femur) and shin bone (tibia) are cut to fit the prosthesis. The undersurface of the kneecap is cut to allow the surgeon to place an artificial piece. The two parts of the prosthesis are placed onto the ends of the femur, the tibia, and the undersurface of the patella using a special bone cement. Usually, metal is used on the end of the femur, and plastic is used on the tibia and patella, for the new knee surface. However, surgeons are now using newer surfaces, including metal on metal, ceramic on ceramic, or ceramic on plastic .In some cases, a mini-incision may be used to avoid cutting the tendon on the front of the knee. This may allow for faster, less painful recovery, but it has risks because of the difficulty of the surgery and the lack of a clear view for the surgeon. Pain is common and to be expected after this type of surgery. Patient may experience numbness towards the outer edge of the incision. The knee temperature may be slightly elevated for several days after surgery. Swelling in the operative leg is a normal part of the postoperative course after surgery, which also limits ROM of the knee.
