Knee replacement surgery is typically recommended for individuals with severe knee pain and disability due to osteoarthritis, rheumatoid arthritis, or other degenerative conditions that have not responded to other forms of treatment.
Knee replacement surgery, also known as knee arthroplasty, is a procedure in which a damaged or diseased knee joint is replaced with an artificial joint. It is typically recommended for individuals with severe knee pain and disability due to osteoarthritis, rheumatoid arthritis, or other degenerative conditions that have not responded to other forms of treatment.
The surgery involves making an incision in the skin and removing the damaged bone and cartilage from the knee joint. The surface of the bone is then prepared to receive the artificial joint, made of metal and plastic components. The artificial joint is then secured in place with cement or a special type of bone cement substitute.
After the surgery, patients typically need to go through a period of rehabilitation to regain strength and mobility in their knee. This can include physical therapy and exercises to improve range of motion, flexibility and strength. Most people are able to return to their normal activities within a few months of surgery.
There are several symptoms that may indicate a need for knee replacement surgery. The most common symptom is chronic knee pain that interferes with daily activities and disrupts sleep. Other symptoms may include stiffness, swelling, and difficulty walking or climbing stairs. In some cases, the knee may give out or become unstable, increasing the risk of falls.
Signs that you may need knee replacement surgery include:
Prior to undergoing knee replacement surgery, a patient will typically undergo a thorough evaluation to determine the cause of their knee pain and determine if surgery is the most appropriate treatment option. This may include a physical examination, imaging tests such as X-rays or MRI, and blood tests to check for underlying conditions such as infection or inflammation. The surgeon may also ask about the patient's medical history and their lifestyle and functional goals to determine if they are a good candidate for the surgery. All of this information is used to create a customized treatment plan for the patient.
