Knee replacement, also known as knee arthroplasty, is a surgical procedure in which damaged or worn-out knee joint surfaces are replaced with artificial implants made of metal, ceramic, or high-grade plastic. These implants are designed to function like a natural knee joint.
Knee replacement is usually recommended for patients suffering from:
Severe osteoarthritis
Rheumatoid arthritis
Post-traumatic arthritis
Long-term knee injury
Difficulty in walking, climbing stairs, or standing for long periods
Knee pain even during rest or sleep
Total Knee Replacement (TKR)
The entire knee joint is replaced with artificial components.
Partial Knee Replacement (PKR)
Only the damaged part of the knee is replaced.
Bilateral Knee Replacement
Both knees are replaced in a single surgery or in stages.
Long-lasting relief from knee pain
Improved walking and movement
Better knee stability and strength
Ability to return to daily activities
Improved overall quality of life
The surgery usually takes 1–2 hours. The damaged cartilage and bone are removed, and the artificial knee joint is placed precisely for smooth movement. Advanced techniques ensure minimal tissue damage and faster recovery.
Walking with support starts within 24–48 hours
Physiotherapy begins soon after surgery
Most patients resume normal activities within 4–6 weeks
Complete recovery may take 3–6 months
Regular exercises and follow-up visits are crucial for long-term success.
Yes, knee replacement is a safe and highly successful procedure when performed by an experienced orthopedic surgeon. Modern implants can last 15–20 years or more with proper care.
