What is Knee Replacement Surgery?
Knee Replacement Surgery, also known as knee arthroplasty, is a surgical procedure where a damaged knee joint is replaced with an artificial implant (prosthesis). This surgery is recommended for patients with severe knee pain or dysfunction caused by conditions such as osteoarthritis, rheumatoid arthritis, or traumatic injury. The goal is to restore mobility, eliminate pain, and improve overall quality of life.
Why is it Done?
- Chronic knee pain that limits daily activities
- Stiffness and swelling that does not improve with medication or physical therapy
- Knee joint damage due to osteoarthritis, rheumatoid arthritis, or post-traumatic arthritis
- Deformities such as bowing in or out of the knee
- Failure of previous non-surgical treatments
