Total knee replacement (TKR) replaces all three knee compartments with a metal-and-polyethylene implant. With robotic assistance, modern TKR offers 95%+ patient satisfaction and 20–25 year implant survival.
Who needs a total knee replacement?
Patients with advanced osteoarthritis, rheumatoid arthritis, or post-traumatic arthritis affecting all three knee compartments are ideal candidates.
If your X-rays show bone-on-bone contact and pain limits walking even short distances, TKR is the most reliable long-term solution.
How is the surgery performed?
A 10–12 cm incision is made over the knee. Damaged cartilage and bone are precisely resurfaced — robot-guided in modern practice — and replaced with anatomically sized implant components.
The patella is resurfaced if needed and the soft tissues are balanced for natural knee motion.
What results can you expect?
Most patients walk within 24 hours, climb stairs by week 2, and return to normal life within 6 weeks.
Long-term, expect pain-free walking, full straightening, and 110–130° of bend — enough for stairs, squatting and most activities.
