Knee replacement surgery is a medical procedure that involves replacing a damaged or worn-out knee joint with an artificial one.
It is typically performed on patients who have severe knee pain or mobility issues due to conditions such as osteoarthritis, rheumatoid arthritis, or injury.
Types of Knee Replacement Surgeries:
There are two main types of knee replacement surgeries: total knee replacement and partial knee replacement.
- Total Knee Replacement: Total knee replacement surgery involves replacing the entire knee joint with an artificial one. This surgery is typically recommended for patients who have severe arthritis or significant knee damage. During the procedure, the surgeon removes the damaged joint and replaces it with a prosthetic knee joint made of metal, plastic, or ceramic.
- Partial Knee Replacement: Partial knee replacement surgery, also known as unicompartmental knee replacement, involves replacing only the damaged portion of the knee joint. This procedure is typically recommended for patients who have arthritis or knee damage in only one area of the knee. During the surgery, the surgeon removes the damaged portion of the joint and replaces it with a prosthetic joint.
