1. Understanding Knee Replacement Surgery
What Is Knee Replacement?
Knee replacement is a surgical procedure that replaces damaged knee joint surfaces with artificial components made of metal and medical‑grade plastic. It’s typically considered when non‑surgical treatments (like medications, physical therapy, injections) have failed and pain or disability significantly impacts daily life.
Types of Knee Replacement
There are three main types:
- Total Knee Replacement (TKR): The entire joint surface is replaced.
- Partial Knee Replacement (PKR): Only the damaged compartment of the knee is replaced.
- Revision Knee Surgery: Replacement of a previously implanted prosthesis due to wear, infection, or instability.
Correct choice depends on disease severity, age, activity level, and surgeon expertise.
Who Needs Knee Replacement?
Typical candidates include individuals with:
- Severe osteoarthritis
- Rheumatoid arthritis
- Significant knee deformity
- Chronic knee pain impacting daily mobility
- Failed conservative treatment
2. What Makes a Top Knee Replacement Surgeon?
