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.
Suitable for patients with a previously implanted knee replacement who are experiencing return of pain, instability, swelling, stiffness, or functional decline that clinical and radiological assessment attributes to implant failure.
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.

"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."

Revision Knee Replacement Cost in Hyderabad
The cost of Revision Knee Replacement in Hyderabad generally ranges from ₹3,50,000 to ₹7,00,000, with an indicative average cost of around ₹5,25,000. Revision knee replacement may be required when a previous knee replacement develops complications such as implant loosening, infection, instability, wear or other problems affecting knee function. The final cost depends on the complexity of revision surgery, implant requirements, bone condition and any additional procedures required.
| Procedure | Approximate Cost Range |
|---|---|
| Revision Knee Replacement | ₹3,50,000 – ₹7,00,000 |
The above range is indicative; the final package and inclusions should be confirmed with the hospital before publication. Revision surgery can be more complex than primary knee replacement and may require specialised implants, bone reconstruction or staged treatment in selected cases.
Factors Affecting the Cost of Revision Knee Replacement
The overall cost of revision knee replacement can vary considerably depending on the reason for revision, condition of the existing implant, amount of bone loss, soft-tissue condition and complexity of reconstruction required.
- →
Reason for revision: The cost may vary depending on whether revision is required because of implant loosening, infection, instability, polyethylene wear, component failure or another complication following the original knee replacement.
- →
Removal of existing implants: Revision surgery may involve removing previously implanted components, which can require additional surgical time and specialised instruments depending on how firmly the components are fixed.
- →
Bone loss and reconstruction: Bone defects around the knee may require bone grafting, augments, sleeves, cones or other specialised reconstruction techniques, which can increase the overall cost.
- →
Revision implants: Revision knee replacement often requires specialised implant components rather than standard primary replacement components. The type and number of components required can significantly affect the final package.
- →
Infection management: When infection is suspected or confirmed, additional investigations, tissue sampling, antibiotic treatment or staged revision surgery may be required depending on the clinical situation.
- →
Soft-tissue and stability issues: Ligament insufficiency, instability, stiffness or other soft-tissue problems may require additional procedures or specialised implants during revision surgery.
- →
Hospital stay and rehabilitation: Revision procedures may require longer hospital observation or admission than primary knee replacement in some patients. Postoperative physiotherapy and rehabilitation may also be required and may be billed separately.
Insurance Coverage for Revision Knee Replacement
Revision Knee Replacement may be covered by health insurance when medically necessary, subject to the patient's policy terms, exclusions, waiting periods, insurer approval and hospital coverage arrangements. Patients should confirm pre-authorisation requirements and applicable coverage with their insurer before treatment.

Dr. Satish Reddy Gandavarapu
Orthopaedic & Joint Replacement Surgeon
Dr. Satish Reddy at Lux Hospitals, Hyderabad, can evaluate patients experiencing persistent pain, stiffness, instability or reduced function following a previous knee replacement and help determine the appropriate revision treatment plan based on clinical examination and diagnostic findings. During the consultation, the doctor may assess: Current knee symptoms: The doctor may review pain, swelling, stiffness, instability, difficulty walking and reduced ability to perform daily activities following the previous knee replacement. Previous knee replacement: Details of the original surgery, implant type, date of surgery and any previous complications, infections or procedures may be reviewed. Implant condition: X-rays and other imaging may be assessed to identify loosening, component position, wear, migration or other changes affecting the existing knee replacement. Bone and soft-tissue condition: The doctor may evaluate bone stock, ligament stability, knee alignment, range of motion and soft-tissue condition to understand the complexity of potential revision surgery. Infection assessment: When clinically indicated, blood tests, joint aspiration or other investigations may be recommended to assess for possible infection around the knee implant. Revision suitability: Based on the clinical findings and investigations, the doctor may determine whether revision knee replacement is appropriate and discuss the expected procedure, potential reconstruction requirements and rehabilitation plan.
