Knee replacement, also known as knee arthroplasty, is a surgical procedure that involves replacing a damaged or worn-out knee joint with an artificial joint. The procedure is typically performed on patients who suffer from severe knee pain or stiffness due to arthritis, injury, or other conditions that affect the knee joint.
During knee replacement surgery, the damaged parts of the knee joint are removed and replaced with an artificial joint made of metal, plastic, or ceramic materials. The artificial joint is designed to mimic the natural movement and function of a healthy knee joint, allowing the patient to move more easily and with less pain.
Knee replacement surgery can be performed using different approaches, such as traditional or minimally invasive techniques. In a traditional knee replacement, a large incision is made in the front of the knee, and the damaged joint is replaced with an artificial joint. In a minimally invasive knee replacement, smaller incisions are made, and specialized surgical instruments are used to remove and replace the damaged joint.
Recovery from knee replacement surgery typically involves a period of physical therapy and rehabilitation to help the patient regain strength, flexibility, and mobility in the knee joint. Most patients are able to resume normal activities, including walking, climbing stairs, and low-impact exercises, within a few months after surgery.
Knee replacement surgery is generally considered to be a safe and effective procedure for patients with severe knee pain or joint damage. However, like any surgery, it does carry some risks, including infection, blood clots, and nerve or blood vessel damage. It’s important to discuss the potential risks and benefits of knee replacement surgery with your doctor before deciding to undergo the procedure.
