Most knee replacement surgeries go well. Patients recover, return to their normal lives, and rarely think about the implant again. But sometimes — for a range of reasons — the original surgery does not provide the relief it should, or the implant begins to fail years later. When that happens, revision knee replacement surgery becomes the necessary next step.
At COJRI, we see patients from across Chandigarh, Mohali, and Panchkula who are living with a knee replacement that is not working as it should. This guide is for those patients — to help them understand what they are experiencing, when to seek help, and what revision surgery involves.
What Is Revision Knee Replacement Surgery?
Revision knee replacement (sometimes called redo knee surgery) is a procedure to replace some or all of the components of a previous knee implant that has failed, worn out, become infected, or is causing pain. It is significantly more complex than a primary (first) knee replacement, requiring specialist expertise, advanced implants, and careful pre-operative planning.
Not every knee problem after replacement requires full revision surgery. Sometimes, smaller interventions are sufficient — but a proper assessment is essential to determine the right course of action.
Common Signs You May Need Revision Knee Surgery
1. Persistent or Returning Pain
Some pain and discomfort after knee replacement is entirely normal in the first 3–6 months. But if pain has returned after a period of good function — or has never really settled — this is a signal worth investigating. Pain that is localised around the implant, worse after activity, or accompanied by warmth and swelling, can indicate loosening, wear, or infection.
2. Instability or Giving Way
A well-functioning knee replacement should feel stable during walking, climbing stairs, and standing. If your knee feels like it might give way, buckles unexpectedly, or feels loose when you put weight on it, the ligament balance around the implant may be off, or the implant components themselves may have shifted.
3. Stiffness That Does Not Improve
Some stiffness in the months following surgery is expected. But a knee that remains severely stiff — where bending beyond 90 degrees is impossible or causes significant pain — may have developed excessive scar tissue (a condition called arthrofibrosis) or may have been positioned in a way that limits normal range of motion.
4. Swelling That Persists
Swelling that does not subside several months after surgery, or that returns after an initial improvement, can indicate an underlying problem. Persistent swelling alongside warmth and redness raises the possibility of a periprosthetic joint infection (PJI) — an infection around the implant — which requires urgent specialist evaluation.
5. A Clicking or Grinding Sensation
Some sounds from a knee replacement are normal. But new clicking, grinding, or scraping sounds — especially if accompanied by pain — can indicate wear of the plastic spacer between the metal components, loosening, or other mechanical failure.
6. Changes Visible on X-Ray
Sometimes the signs of implant failure are visible on imaging before symptoms become severe. Changes in implant position, bone loss around the implant (called osteolysis), or progressive loosening identified on follow-up X-rays are all indications that revision surgery may be required in the near future.
Common Reasons Knee Implants Fail
- Aseptic loosening: The most common cause — over time, the bond between the implant and bone weakens, usually due to small particles released from the plastic spacer triggering a low-grade immune response.
- Periprosthetic joint infection (PJI): Infection around the implant, which can develop months or even years after the original surgery.
- Implant wear: The plastic spacer between the metal components gradually wears down, changing the dynamics of the joint.
- Knee instability: Incorrect ligament balance at the time of initial surgery, or ligament injury after surgery, can lead to the knee feeling unstable.
- Stiffness (arthrofibrosis): Excessive scar tissue formation that limits joint movement.
- Periprosthetic fractures: Fractures that occur around the existing implant — often due to a fall or accident — may require specialised surgical management.
What Does Revision Knee Replacement Involve?
Revision knee replacement is considerably more involved than a primary procedure. The existing implant components need to be carefully removed — this can be complex if they are well-fixed. Any bone loss caused by the failing implant needs to be addressed, sometimes with bone grafts or specialised implant components. The new implant is typically more complex and constrained than the original.
The procedure requires expertise that goes beyond standard joint replacement training. At COJRI, revision knee surgery is performed by surgeons with specific experience in complex revision cases from across Chandigarh, Mohali, and the wider Tricity region.
Recovery After Revision Knee Replacement
Recovery from revision surgery is typically longer than from a primary replacement — often 6–12 months before full functional restoration. This is because the bone and soft tissue around the joint have already been through one surgical episode, and the more complex revision procedure requires additional healing time.
Physiotherapy is critically important after revision surgery. Our team at COJRI provides dedicated post-operative rehabilitation support to help patients recover as efficiently and completely as possible.
Frequently Asked Questions About Revision Knee Surgery
How do I know if my knee replacement has failed?
The clearest signs are pain that returns after a period of good function, new instability, persistent swelling, or signs of infection (warmth, redness, fever). If you are experiencing any of these, see your orthopaedic surgeon promptly. Do not wait for the next scheduled check-up.
Can revision knee surgery be done in Chandigarh?
Yes. COJRI offers specialist revision knee replacement services in Chandigarh, with specific expertise in complex revision cases including those involving infection, bone loss, and significant instability.
Is revision knee replacement more risky than primary replacement?
Revision surgery is more complex and does carry a higher risk profile than primary replacement — but in the hands of experienced revision specialists, outcomes can be excellent. The key is seeking specialist assessment early rather than living with a failing implant for too long.
What if my knee replacement was done at a different hospital?
Many of our revision patients have had their original surgery elsewhere. We review all available records, imaging, and surgical notes to plan the best revision approach for your specific situation.
How soon after my primary surgery can revision be done?
This depends entirely on the reason for revision. Infection may require intervention within weeks. Mechanical loosening that develops over years can be managed electively once identified. Your COJRI specialist will advise the appropriate timing for your situation.
