Understanding Knee Replacement

Knee replacement, also known as knee arthroplasty, is a surgical procedure in which damaged or worn-out parts of the knee joint are replaced with artificial implants made of metal, ceramic, or medical-grade plastic. It is commonly recommended for individuals with severe knee pain, stiffness, and reduced mobility caused by arthritis, injury, or degenerative joint disease when non-surgical treatments no longer provide relief.

The procedure helps restore joint function, reduce pain, and improve quality of life.

Knee Replacement Techniques

Total Knee Replacement (TKR): The entire knee joint is replaced with artificial components. Most common for advanced arthritis affecting the whole knee.

Partial Knee Replacement (PKR): Only the damaged part of the knee is replaced, preserving healthy bone and tissue. Suitable for arthritis in one knee compartment.

Robotic-Assisted Knee Replacement: Uses robotic technology to help the surgeon position the implant with high precision, improving outcomes.

Revision Knee Replacement: Replaces or repairs a previous artificial knee joint that has worn out or developed complications.

Common Causes:

Osteoarthritis
Wear-and-tear arthritis
Rheumatoid Arthritis
Autoimmune arthritis
Post-Traumatic Arthritis
After injury
Severe Fractures
Major knee breaks
Ligament Injuries
Torn knee ligaments
Cartilage Damage
Cartilage loss
Congenital Deformities
Joint malformation
Avascular Necrosis
Bone tissue death

Modern knee implants typically last 15 to 20 years or longer, depending on the patient's age, activity level, and overall health.

Most patients begin standing and walking with assistance within 24 hours after surgery under the guidance of a physiotherapist.

Patients with desk jobs can usually return to work within 4 to 6 weeks, while those with physically demanding jobs may require 2 to 3 months or longer.

Yes. Physiotherapy is an essential part of recovery and helps restore knee strength, flexibility, and function while improving long-term outcomes.
