Corrective implant surgery
Revision Knee Replacement in Ahmedabad, Gujarat
Revision knee replacement is a corrective procedure to replace a failed, loose, worn or infected knee implant with a new one, restoring stability, mobility and pain-free movement. It is far more complex than a first-time replacement and demands the surgical expertise Dr. Hiren Patel brings from 13+ years and 11,000+ joint surgeries.
- For failed, loose, infected or worn implants
- Two-stage revision for infected implants
- Bone grafts and augmented implants where needed
- Revision implants typically last 10-15 years
Signs you may need revision surgery
Persistent pain, swelling, or a feeling that the knee is giving way long after a previous replacement are the most common signs that an implant is failing and needs assessment.
- Implant loosening
- Infection around the implant
- Knee instability or giving way
- Implant wear and tear
- Fractures around the implant
How revision surgery is performed
The old implant is removed, bone surfaces are prepared, and a new implant is placed - sometimes with bone grafts or specialised augmented implants where bone stock has been lost. Infected implants are usually treated with a two-stage revision: a temporary antibiotic spacer clears the infection first, followed by the final implant once the joint is clean.
Recovery
Recovery is slower than after a primary knee replacement. Most patients regain significant mobility within 3 to 6 months, though full recovery can take up to a year depending on individual circumstances and the complexity of the revision.
Frequently asked questions
Why is revision knee surgery more complex than the first replacement?
Revision surgery deals with bone loss, scar tissue and sometimes infection from the original implant, and carries a higher risk of complications than a primary knee replacement - it requires specialised implants and surgical planning.
How long do revision knee implants last?
Revision knee implants typically last 10 to 15 years with proper care, somewhat less than a primary implant due to the more complex bone and soft-tissue environment.
What causes a knee implant to fail?
Common causes include implant loosening, infection, instability, wear and tear, and fractures around the implant.
Is Dr. Hiren Patel experienced in revision knee surgery?
Yes. Revision cases are handled with 13+ years of experience and 11,000+ successful joint surgeries at PMG Hospital.
