Sports injuries, fractures, or ligament damage can lead to long-term knee degeneration.
- Chronic Knee Pain
Persistent pain that affects walking, climbing stairs, or sleeping may require surgical intervention.
Types of Knee Replacement Surgery
- Total Knee Replacement (TKR)
In a total knee replacement, the entire knee joint is replaced with prosthetic components. This is the most common type of knee surgery.
- Partial Knee Replacement (PKR)
Only the damaged portion of the knee is replaced. This option is suitable for patients with limited joint damage.
