Knee replacement surgery is a procedure that replaces a problem joint or joints in the knee with artificial material so that the patient can live a more active lifestyle as well as reduce the pain. The knee acts as a hinge joint so that motion is given to the leg, because the joints in the knee are used so often normal that wear and tear can occur. There are several types of joint replacements but physical therapy is required in all knee replacement surgeries.
Facts
Due to modern technology, knee replacement surgery has become a very common and very successful surgery. The troubled knee will be totally or partially replaced which allows the patient to enjoy normal activities without the joint pain or swelling. Most patients will regain their ability to perform normal active activities and return to everyday life within six to eight weeks. As with most surgeries, knee replacement has its benefits and risk. Arthritis, normal wear and tear or the ligaments in the knee or an accident are all common causes of knee replacement surgery.
Significance
According to studies done by the Mayo Clinic, there is a dramatic reduction of pain in the knee. More than 90 percent of patients improve their ability to do activities. Knee surgery will not increase any abilities. Knee replacements can last for several years with the proper maintenance. The knee may experience pain if there is substantial wear and tear to the plastic cushions. Excessive weight or over activity may increase the time of normal wear and tear.
Types
There are three main type of knee replacement surgeries preformed. Total knee replacement surgery, which is also known as knee arthroplasty, is the replacement of severely damaged cartilage tissue with a plastic or metal prosthesis. The function of the knee joint is duplicated by the prosthesis. Unicompartmental knee replacement surgery, which is also called partial knee replacement, is when the damaged section of the joint is replaced with implants. This surgery is done when a compartment in one of the knees are damaged. Bilateral knee replacement surgery is when both knees are replaced at the same time. This usually occurs in patients with severe arthritis.
Benefits
There are a number of benefits that come with knee replacement surgery. After knee surgery, there is less pain which allows a person to lead a more active life and improve their overall quality of life. The range of motion in the knee will also increase after surgery. An artificially knee is never as good a healthy real knee but the knee will have more flexibility than before surgery. An artificial knee can last for a long time and can be replaced when needed.
Warnings
Only 2 percent of knee replacement patients experience serious complications which include knee joint infection, heart attack or stroke. Patients with a chronic illness are at an increased risk for complications during surgery or a prolonged recovery. Scarring of the knee can occur or limited motion in patients with serious motion limitations prior to surgery. Blood clots in the leg veins are commonly found after knee replacement surgery. A prevention plan will be outlined by the physician for recovery.
