The knee joint relies on smooth cartilage and synovial fluid for pain-free movement. Aging, injury, overuse, or conditions like osteoarthritis can wear down cartilage, weaken ligaments, and cause joint stiffness, swelling, and chronic pain.

Knee replacement (knee arthroplasty) is a surgical procedure where the damaged surfaces of the knee joint are replaced with artificial implants. This restores smooth movement, reduces pain, and improves function.

• Patients with severe knee arthritis not relieved by medications or physiotherapy
• Individuals with fractures or trauma affecting the knee joint
• Patients with limited mobility and persistent knee pain affecting daily activities

• Total knee replacement: Both sides of the knee joint (femoral and tibial surfaces) are replaced
• Partial knee replacement: Only the damaged compartment of the knee is replaced
• Revision knee replacement: Replacement of a previous implant that has worn out or failed

Modern knee implants typically last 15–20 years, depending on activity level, implant type, and adherence to post-operative care.

The surgery is performed under anesthesia, so there is no pain during the procedure. Post-operative discomfort is generally mild and managed with medications, ice therapy, and guided physiotherapy.

• Immediate post-op: Walking with a walker or support, gentle knee movements
• 2–6 weeks: Gradual physiotherapy to regain knee flexibility and strength
• 6–12 weeks: Increased walking distance, return to light daily activities
• 3–6 months: Full functional recovery, return to normal activities, and low-impact sports if cleared by your surgeon
