What is Knee Replacement?
Knee Replacement, medically known as Total Knee Replacement, is a surgical procedure in which a damaged or worn-out knee joint is replaced with an artificial implant. The procedure is usually recommended when severe pain, stiffness, or loss of movement affects daily activities and other treatments are no longer effective.
During surgery, the damaged cartilage and bone in the knee joint are removed and replaced with prosthetic components made of metal, plastic, or ceramic materials. These implants recreate the natural movement of the knee and significantly reduce pain.
Knee replacement is one of the most successful procedures in modern Orthopedic Surgery, helping millions of patients regain mobility and improve their quality of life.
Types of Knee Replacement
- Total Knee Replacement
- Partial Knee Replacement
- Revision Knee Replacement
1. Total Knee Replacement (TKR)
Total Knee Replacement is the most common type of knee replacement surgery.
In this procedure:
- The entire knee joint surface is replaced.
- Both sides of the joint (femur and tibia) are resurfaced with implants.
- It is recommended for severe arthritis or major joint damage.
Benefits
- Significant pain relief
- Improved mobility
- Long-lasting results (15–25 years in many cases)
2. Partial Knee Replacement (PKR)
Partial Knee Replacement replaces only the damaged portion of the knee rather than the whole joint.
It is suitable when arthritis affects only one compartment of the knee.
Advantages
- Smaller surgical incision
- Faster recovery
- More natural knee movement
3. Revision Knee Replacement
Revision Knee Replacement is performed when a previous knee implant wears out, loosens, or fails.
This procedure replaces the old implant with a new prosthetic joint.
Common Conditions That Require Knee Replacement
Knee replacement is usually recommended for severe joint damage caused by conditions such as:
- Osteoarthritis
- Rheumatoid Arthritis
- Post-Traumatic Arthritis
- Severe knee injuries or fractures
- Degeneration of cartilage due to aging
