Knee replacement surgery, also known as knee arthroplasty, is a surgical procedure in which the damaged parts of the knee joint are removed and replaced with artificial components. This procedure is typically recommended for individuals who have severe knee pain and limited mobility due to arthritis, injury, or other degenerative conditions. The surgery is performed under general anesthesia and typically takes 1-3 hours to complete.
During the procedure, the damaged cartilage and bone are removed from the thighbone (femur), shinbone (tibia), and kneecap (patella). The surfaces of these bones are then shaped to fit the artificial components, which are made of metal and plastic. These components are designed to mimic the function of the natural knee joint and allow for smooth, pain-free movement.
After surgery, patients will typically be required to spend several days in the hospital for recovery. Physical therapy will be started soon after the surgery to regain the strength and range of motion in the knee. It may take several months for the knee to fully heal and for the patient to regain their full range of motion and strength.
Overall, knee replacement surgery can be a very effective treatment option for individuals with severe knee pain and limited mobility due to arthritis, injury, or other degenerative conditions. However, it is important to note that the surgery is not appropriate for everyone and a thorough evaluation by an orthopedic surgeon is necessary to determine if it is the best option for an individual patient.
