Revision Knee Replacement
Revision knee replacement addresses a knee implant that is painful, stiff, loose, unstable or infected. Establishing exactly why the knee has failed is the essential first step. Revision without a diagnosis rarely succeeds.
Finding the cause first
A painful knee replacement always has a reason: loosening, infection, instability, malalignment, stiffness or soft-tissue problems. A structured assessment (examination, imaging, blood tests and joint aspiration) identifies the cause. If no cause can be found, revision surgery is unlikely to help, and Paddy Subramanian will say so plainly.
The operation
Revision knee surgery replaces some or all of the components, restores the alignment and balance of the limb, and reconstructs any bone loss with augments or specialist implants. Infection is treated with single or two-stage revision alongside microbiology colleagues.
Recovery and outlook
Recovery is more gradual than after a primary knee replacement, with physiotherapy central to the result. Most patients achieve substantial relief of pain and reliable function, though a revised knee rarely feels as natural as a well-functioning first-time replacement. Expectations are discussed honestly before surgery.
Read more before you decide
Dr Subramanian has been approachable, professional and allowed me to consider what is a major surgery with confidence. All my questions were answered and I felt involved in the decision making. I am now back on my feet with a neat scar. I would recommend him highly to anyone.
