JOINT REPLACEMENT

Revision Knee
Replacement
A specialised procedure to replace a worn, loose, infected or failed knee implant — restoring stability and function when your first replacement hasn't lasted.
Revision knee replacement, at a glance.
A quick summary of what the procedure involves, who it's for, and what to expect — from recovery to cost.
Revision knee replacement removes a worn, loose, infected or failed implant and replaces it with new, specialised components — often with bone grafting to restore lost bone. Recommended for patients with implant failure, persistent pain or instability after a prior replacement. Surgery is more complex and hospital stay longer than a first-time replacement, at 4 to 7 days, with steady improvement over 3 to 6 months.
ABOUT THE TREATMENT
Specialised Care for a Failed Implant
Not every knee replacement lasts forever. Implants can wear, loosen, become infected, or fail due to instability or fracture around the joint. Revision knee replacement carefully removes the failed components, addresses any bone loss with grafting or augments, and places a new, specially designed implant built for the demands of a second surgery. Dr. Unmesh approaches every revision case individually, since no two failed implants present the same challenges.

HOW THE SURGERY WORKS
A Step-by-Step Journey
Revision surgery calls for careful planning at every stage — here's what the process looks like.
01
Evaluation of Implant Failure
We assess your symptoms, imaging and history to confirm why your implant has failed.
02

Detailed Surgical Planning
Advanced imaging helps plan implant removal and any bone reconstruction needed.
03
Implant Removal & Reconstruction
The failed implant is carefully removed, bone loss addressed, and a new implant placed.

FREQUENTLY ASKED QUESTIONS
Your Questions, Answered
What is revision knee replacement?
Revision knee replacement is a specialised surgery that removes a worn, loose, infected or otherwise failed knee implant and replaces it with new components, often requiring bone reconstruction.
Why would I need a revision?
Common reasons include implant loosening or wear over time, infection, instability, stiffness, fracture around the implant, or persistent pain that hasn't resolved after the original replacement.
Is revision surgery riskier than primary replacement?
Revision surgery is more complex than a first-time replacement because it involves removing existing components and addressing any bone loss, so it typically takes longer and carries a higher level of surgical complexity.
How is bone loss around the old implant managed?
Depending on the extent of bone loss, Dr. Unmesh may use bone grafting, metal augments or specialised revision implants designed to restore stability and support long-term function.
What if the implant failed due to infection?
Infected implants may require a staged approach — removing the infected implant, treating the infection, and then placing a new implant once the joint is clear, to protect long-term outcomes.
How long does revision surgery take?
Revision knee replacement generally takes longer than a primary replacement, often 2 to 3 hours, depending on the complexity of implant removal and bone reconstruction required.
How long is the hospital stay and recovery?
Hospital stay is typically 4 to 7 days, with a more gradual recovery than primary replacement. Most patients see steady improvement over 3 to 6 months, with continued gains for up to a year.
Will my new implant last as long as the first one?
Revision implants are built for durability, though outcomes depend on bone quality and the reason for revision. Dr. Unmesh will discuss realistic expectations specific to your case.
How do I know if my implant has failed?
Warning signs include increasing pain, swelling, instability, stiffness, a grinding or clicking sensation, or visible changes on X-ray. Any of these should prompt a prompt evaluation.
Am I a candidate for revision surgery?
Candidacy depends on the cause and severity of implant failure, your bone quality and overall health. Dr. Unmesh will confirm suitability through examination, imaging and relevant investigations.
