TKA stands for Total Knee Arthroplasty. It's also commonly referred to as a total knee replacement (TKR). This surgical procedure involves replacing the damaged surfaces of the knee joint with artificial components.
Understanding Total Knee Arthroplasty (TKA)
Total knee arthroplasty is a highly effective and common orthopedic surgery. It's a solution for individuals suffering from end-stage degenerative knee osteoarthritis and other conditions causing significant knee pain and dysfunction. The procedure involves removing the damaged parts of the femur (thigh bone), tibia (shin bone), and patella (kneecap) and replacing them with prosthetic implants made of metal and plastic. This "resurfacing" allows for improved joint function and pain relief.
Several sources confirm the widespread use and success of this procedure:
- High Effectiveness and Cost-Efficiency: Multiple sources (StatPearls, eMedicine, CMS) highlight TKA as a highly effective and cost-efficient surgical procedure in orthopedics.
- Long History and Evolution: The procedure has been performed for over 50 years (eMedicine), with continuous improvements in techniques and implant design.
- Common Procedure: It's described as a common orthopedic surgery involving the replacement of articular surfaces (Physiopedia).
- Interchangeable Terms: The terms "Total Knee Arthroplasty" (TKA) and "Total Knee Replacement" (TKR) are used interchangeably (WrightPT).
While the procedure is highly effective, patients should be aware that it's a major surgical intervention with potential risks and complications. It's crucial to discuss these with your orthopedic surgeon before making a decision.
