Which term describes the surgical replacement of the knee joint?

• A. Hip Replacement
• B. Fracture
• C. Knee Replacement
• D. Inflammation

Answer: (C)

Replacing a damaged knee joint surgically is called a knee replacement. This procedure, also known as knee arthroplasty, involves resurfacing or replacing the worn ends of the femur and tibia (and sometimes the patella) with artificial components to restore smooth movement, reduce pain, and improve function. It’s typically considered when pain and disability persist despite other treatments due to conditions like osteoarthritis, rheumatoid arthritis, or significant knee injury. There are variations, such as total knee replacement (replacing all surfaces) or partial knee replacement (replacing only the damaged compartment).

In contrast, hip replacement involves the hip joint, a fracture is a bone break, and inflammation refers to swelling from an immune response. The term that describes the surgical replacement of the knee joint is knee replacement.
