What Is Knee Replacement 2026?

Knee replacement, also known as knee arthroplasty, is a surgical procedure where a damaged or arthritic knee joint is replaced with an artificial one. This procedure is designed to alleviate severe knee pain and restore mobility in individuals who have exhausted conservative treatments.

Knee replacement surgery has become a common and effective solution for individuals suffering from knee pain and limited mobility. The procedure involves replacing the damaged or arthritic knee joint with an artificial one, which is designed to mimic the natural movement and function of the knee joint.

How Does Knee Replacement Work?

During the surgery, the surgeon removes the damaged or arthritic knee joint and replaces it with an artificial joint made of metal, plastic, or ceramic components. The artificial joint is designed to mimic the natural movement and function of the knee joint.

The surgery typically involves the following steps:

1. Preparation: The patient is given general anesthesia or regional anesthesia to numb the leg.

2. Incision: The surgeon makes an incision in the skin to access the knee joint.

3. Removal of damaged tissue: The surgeon removes the damaged or arthritic tissue from the knee joint.

4. Implantation of artificial joint: The artificial joint is implanted, and the surrounding tissue is secured to the new joint.

5. Closure: The incision is closed, and the patient is taken to the recovery room for monitoring.

1. Severe knee pain: Pain that interferes with daily activities and sleep.

In addition to these common indications, knee replacement surgery may also be recommended for individuals with:
