Revision Knee Replacement — When a Previous Replacement Fails
Re-doing a knee replacement that has loosened, become infected, become unstable or was not aligned correctly. This is among Dr Reddy's core areas of work.
When this is considered
- ◆Pain that never settled after a knee replacement, or returned after a pain-free period
- ◆The knee gives way, feels unstable or the leg has changed shape
- ◆Swelling, warmth, fever or a discharging wound — possible infection, which needs urgent review
- ◆X-ray showing a loose implant, wear, or bone loss around the implant
Having one of these does not mean you need surgery. It means the problem is worth examining properly.

Telugu lo matladandiHow it is approached
Revision surgery without a diagnosis usually fails. Blood tests for infection, joint fluid aspiration, X-rays and often a CT scan are done to identify why the knee is failing.
If infection is confirmed, the treatment path is different — it may involve a washout, or a two-stage revision with a temporary spacer and antibiotics before the new implant is placed.
Where bone has been lost around the old implant, metal augments, cones or sleeves and stemmed implants are used to restore support and stability.
The aim is to return the joint line and ligament balance to near-normal, which is what decides whether the revised knee feels stable.
Typical recovery
Timelines are typical, not promised. Yours depends on your age, general health and how the surgery goes.
Common questions
+My surgery was done elsewhere. Can I still come?
Yes. Bring your operation notes, implant details if you have them, and all X-rays. A second opinion does not commit you to surgery.
+Is revision surgery riskier?
It is a bigger operation than a first replacement and takes longer, so it is planned carefully with a full medical assessment beforehand.
+Will I get back to how I was?
The realistic goal is a stable, much less painful knee. Outcomes depend heavily on why the first replacement failed and how much bone remains.
