Which procedure is abbreviated TKR?

• A. Knee Arthroplasty
• B. Hemiarthroplasty
• C. Total Knee Replacement
• D. Osteotomy

Answer: (C)

The main idea is recognizing what the abbreviation TKR stands for. TKR means total knee replacement—the procedure that replaces the entire knee joint surfaces with artificial components. This is a full joint replacement, typically performed for advanced knee arthritis or severe joint damage, and it involves resurfacing or replacing the femur, tibia, and often the patella.

Knee arthroplasty is a broad term for replacing a knee joint, but the specific abbreviation TKR refers to the complete replacement rather than a partial or other form. A hemiarthroplasty is a partial joint replacement, not a full knee replacement. An osteotomy is a bone-cutting realignment procedure, not a joint replacement. So the procedure abbreviated TKR is the Total Knee Replacement.
