Revision Knee Replacement

Q: What causes a knee replacement to fail over time?

Common failure modes include aseptic loosening from wear debris, polyethylene liner wear, joint instability, periprosthetic fracture, and infection. Understanding which mode has caused the failure determines the entire approach to revision surgery.

Q: How do I recognise that my knee replacement may have failed?

Warning signs include new or worsening knee pain after a previously comfortable period, progressive swelling, instability, reduced movement, or mechanical symptoms such as clicking and giving way. Updated X-rays and blood tests are the first investigation step.

Q: Is revision knee surgery more risky than a primary replacement?

Yes — revision surgery carries higher risks due to bone loss, scarring, longer operating time, and greater blood loss. However, with meticulous planning and appropriate implant selection, the majority of revision patients achieve meaningful improvement.

Q: How long does recovery from revision knee replacement take?

Recovery is longer than after a primary replacement. Most patients begin mobilising within days, but achieving full functional independence typically requires 6–12 months of structured rehabilitation, depending on the complexity of the revision performed.

When a previous knee replacement no longer functions as intended — due to wear, loosening, or infection — this corrective procedure removes the failed implant and restores the joint to reliable, pain-free function.

What is Revision Knee Replacement?

Revision knee replacement addresses the failure of a previously implanted knee prosthesis — removing the worn or failed components and reconstructing the joint with specialised revision implants. The procedure is considerably more demanding than a primary replacement because scar tissue, bone loss around the implant, and the need for extended fixation systems all add complexity. At Lux Hospitals, Dr. Sai Kishan undertakes a detailed pre-operative investigation of every revision case — including imaging, blood markers, and joint fluid analysis — to establish precisely why the first replacement failed before determining the revision strategy.

Indicated when a previously implanted knee replacement produces progressive pain, instability, reduced range of motion, mechanical failure, or confirmed infection — and where thorough clinical and laboratory assessment has identified the underlying cause driving the need for revision surgery.

How the Procedure Works

Failure Mode Analysis

Advanced imaging, infection screening blood tests, and joint aspiration confirm the cause of failure and guide selection of the revision implant system.

Anaesthesia & Approach

The previous scar is used wherever possible; meticulous soft tissue dissection exposes the failed prosthesis in full.

Implant Extraction & Bone Assessment

Failed components are carefully removed; bone defects are catalogued and planned for treatment with augments or structural graft.

Revision Implant Reconstruction

Stemmed revision implants with appropriate augments are fixed to provide durable stability in the compromised bone stock.

Closure & Rehabilitation Programme

The wound is closed with care; a tailored rehabilitation programme begins early, progressing according to individual recovery milestones.

Who Needs This Treatment?

→Resolves pain and instability from a failed, infected, or mechanically worn implant
→Restores functional movement to a knee that has progressively deteriorated
→Bone deficiency addressed with modern augmentation and grafting techniques
→Staged revision protocols available when prosthetic joint infection is confirmed
→Revision-specific implant systems designed for use in compromised bone
→Thorough pre-operative failure analysis reduces the risk of repeat failure

Revision knee surgery demands an entirely different level of pre-operative investigation. You cannot plan what you do not understand — identifying why the first replacement failed is the single most important part of this procedure.
