The standard pain management program after knee replacement surgery involves pain medications prescribed by the patient's physician, physical therapy and knee-strengthening exercises, reports Mayo Clinic. The program of treatment for unusual pain following surgery depends on the reason for the pain, but it may include further medications and physical therapy or revision knee replacement surgery, explains Dr. Jonathan Cluett for About.com.
After knee replacement surgery, health care specialists often encourage patients to begin standing and walking the same day, which helps with pain management by mobilizing the joint and strengthening muscles, states the National Institute of Arthritis and Musculoskeletal and Skin Diseases. Some patients may initially need to use a walker or cane to manage the discomfort and pain following joint replacement surgery. Physical therapy to regain joint range of motion commences as early as the day after surgery. Prescription pain medications handle normal postsurgery pain, which usually continues for a few weeks to a few months.
Determining the cause of continuing pain after knee replacement surgery is essential in treating it, says Dr. Cluett. For instance, physicians may treat minor infections with drugs, but deeper infections may necessitate another operation, according to the National Institute of Arthritis and Musculoskeletal and Skin Diseases. Treatment of blood clots in the legs may involve blood-thinning drugs and support stockings or boots. Joint dislocation is correctable without surgery, but the patient may have to temporarily wear a brace. Surgery may be necessary to repair loosening or wear in the joint.
