Revision Knee Replacement
Removal of a failed or worn knee replacement and re-implantation with new specialised components — addressing loosening, wear, infection, or instability in a previously replaced knee.
What is Revision Knee Replacement?
Revision knee replacement is the re-operation to remove a failed primary knee implant and replace it with new components. It is significantly more complex than primary knee replacement because of bone loss, scarring, and the altered anatomy left by the previous surgery. Specialised revision implants — with longer stems, augments, and greater constraint — are required to achieve stable fixation. Common reasons for revision include aseptic loosening, polyethylene wear, deep periprosthetic infection, instability, and periprosthetic fracture. Early recognition of failure and prompt referral to a revision specialist leads to the best outcomes.
How the Procedure Works
Pre-op Assessment
CT scan, MRI, blood tests (ESR, CRP), and aspiration if infection is suspected — full understanding of failure mechanism is essential before planning revision.
Implant Removal
Failed components are carefully removed while preserving as much viable bone stock as possible.
Bone Defect Management
Bone defects are classified and managed with augments, structural allograft, or metal metaphyseal cones.
Revision Implant Fixation
Longer-stemmed, constrained revision components provide stability in compromised bone.
Structured Rehabilitation
Longer and more closely supervised than primary replacement — physiotherapy is critical throughout the 6–12 month recovery.
Outcomes
Who Needs This Treatment?
- →Expert identification of the exact failure mechanism before re-operation
- →Specialised revision implant systems for bone-deficient situations
- →Two-stage revision protocol for infected implants — highest eradication rate
- →Supervised rehabilitation programme tailored to revision patients
- →Full referral and investigation network for complex cases
"Revision knee replacement requires as much planning as execution. Understanding exactly why the primary replacement failed — whether it is wear, loosening, infection, or instability — determines the entire approach. There are no shortcuts in revision surgery."
