Knee Replacement
When knee arthritis severely limits movement and causes constant pain, knee replacement surgery replaces the damaged joint surfaces with a prosthetic implant — restoring mobility and quality of life.
Overview
Knee replacement (arthroplasty) is one of the most successful surgeries in modern medicine. It involves removing the worn-out cartilage and bone from the knee joint and replacing them with metal and plastic components that mimic natural knee movement. Both total knee replacement (TKR) and partial (unicompartmental) replacement are available depending on the extent of damage.
Our orthopaedic surgeons use advanced alignment techniques and high-quality implants to ensure the prosthetic knee lasts 15-20+ years. With enhanced recovery protocols, most patients walk with support within 24 hours and are discharged in 2-4 days.
Causes
- Osteoarthritis — age-related wear and tear of cartilage
- Rheumatoid arthritis — autoimmune inflammation destroying joint lining
- Post-traumatic arthritis — from previous knee injuries or fractures
- Avascular necrosis — bone death from loss of blood supply
- Severe deformity (bow legs or knock knees)
Symptoms
- Persistent knee pain that limits daily activities like walking and climbing stairs
- Pain even at rest, including at night
- Stiffness and inability to fully straighten or bend the knee
- Swelling that doesn't respond to medication
- Bow-legged or knock-kneed deformity
- No relief from physiotherapy, injections, or painkillers
Diagnosis
- Physical examination — assessing range of motion, stability, and deformity
- X-rays — show joint space narrowing, bone spurs, and alignment
- MRI — evaluates soft tissue damage (cartilage, meniscus, ligaments)
- Blood tests — check for rheumatoid arthritis markers
Treatment Options
Total Knee Replacement (TKR)
Replaces all three compartments of the knee. Suitable for advanced arthritis affecting the whole joint.
Partial Knee Replacement (PKR)
Only the damaged compartment is resurfaced. Preserves healthy bone and ligaments with faster recovery.
Robotic-assisted knee replacement
3D pre-planning and robotic precision for optimal implant positioning and alignment.
Non-surgical management
Physiotherapy, hyaluronic acid injections, steroid injections, and weight loss for early arthritis.
Frequently Asked Questions
How long does a knee replacement last?
Modern implants last 15-20+ years in 90%+ of patients. Younger, active patients may eventually need a revision.
When can I walk after knee replacement?
You'll stand and take a few steps with a walker within 24 hours. Most patients walk independently by 4-6 weeks and resume all activities by 3 months.
