TKR stands for Total Knee Replacement, also known as Total Knee Arthroplasty (TKA). It's a surgical procedure where damaged parts of the knee joint are replaced with artificial (prosthetic) components. This surgery aims to alleviate significant pain and improve function in severely damaged knees.
Understanding the Procedure
A normal knee acts as a hinge joint connecting the thighbone (femur) to the lower leg bones (tibia and fibula). In a TKR, parts of these bones, along with the kneecap (patella, optionally), are replaced with artificial implants made of durable materials like metal and plastic. The artificial parts are designed to mimic the natural movement and function of the knee joint.
Why is TKR Performed?
TKR is typically performed to relieve severe pain and disability caused by conditions such as:
- Osteoarthritis
- Rheumatoid arthritis
- Severe knee injuries
The Procedure's Impact
The procedure significantly improves mobility and reduces pain for many patients. However, it's crucial to remember that the artificial joint may eventually require revision surgery in the future. Patellar resurfacing, the replacement of the kneecap's articular surface, is optional during TKR, with varying practices among surgeons.
Key Takeaways
- TKR is a major surgical procedure requiring significant recovery time.
- Post-operative physical therapy is essential for optimal results.
- Potential risks and benefits should be carefully discussed with a medical professional before undergoing the surgery.
