Knee replacement surgery is a common orthopedic procedure that helps alleviate severe knee pain and restore mobility in patients suffering from conditions like osteoarthritis, rheumatoid arthritis, or injury-related damage. Understanding the cost and factors influencing it is crucial for patients planning this surgery in the USA.
What is Knee Replacement Surgery?
Knee replacement surgery, also known as knee arthroplasty, involves removing the damaged portions of the knee joint and replacing them with artificial components made of metal, ceramic, or plastic. There are two main types:
- Total Knee Replacement (TKR): The entire knee joint is replaced.
- Partial Knee Replacement (PKR): Only the damaged part of the knee is replaced.
