Revision Knee Replacement
Revision surgery replaces a worn, loose or infected knee implant. It is complex reconstruction: the cause must be identified, bone loss managed and stability rebuilt.

1:26Recovery After Revision Surgery
Realistic milestones after revision surgery, and how rehabilitation is staged.
Specialist Surgery
3–5 Nights Stay
120–180 Minutes
Stability RestoredSurgical Steps (Overview)
Cause Investigation
Blood tests, joint aspiration and imaging identify loosening or infection.
Implant Removal
Existing components are removed with bone preserved wherever possible.
Defect Management
Bone loss is filled with augments, cones or bone graft.
Reconstruction
Revision implants with added constraint restore stability.
Balance & Closure
Alignment and soft-tissue balance are verified before closure.
Recovery Timeline (Step by Step)
Week 1Hospital rehabilitation · Assisted walking · Wound and pain management
Week 2–6Walking with aids · Motion work · Weight bearing as instructed
Week 6–12Reducing aids · Strength and gait retraining
Month 3–6Independent walking · Endurance · Daily activities resumed
Month 6–12Continued gains · Low-impact activity*A painful replacement always has a reason: loosening, infection, instability, stiffness, wear or malalignment. Revision without a diagnosis rarely helps, so the work-up comes first.
Two-stage surgery is standard when infection is present. In mechanical failure, one operation usually suffices, with revision implants designed to compensate for lost bone and ligament support.
- Persistent pain or swelling after a knee replacement
- X-ray evidence of loosening, wear or component failure
- Instability, giving way or recurrent dislocation
- Confirmed or suspected implant infection
- Complete work-upInflammatory markers, aspiration and cross-sectional imaging
- Medical optimisationAnaemia, diabetes and dental health addressed beforehand
- Realistic goalsRevision aims for a stable, comfortable knee — we set expectations together
- Support planningA longer hospital stay and more help at home should be arranged
In revision surgery the diagnosis is the operation. Infection, loosening and instability look alike from the outside and are treated completely differently — so we take the time to know which one we are facing.
