KNEE SURGERY
Revision Knee Replacement
Modern knee replacements usually last more than 15 to 20 years, though components can wear out, loosen or become painful over time. Revision Knee Surgery involves replacing the original prosthesis with new components to improve joint function. This procedure is more complex than the initial surgery and requires detailed pre-operative planning. Dr David Kitchen performs these specialised reconstructions, consulting at sportsmed Stepney and Henley Beach.
What is Revision Knee Replacement?
Revision Knee Surgery involves the removal of existing hardware first. It is a specialised surgery that replaces old femoral and tibial components with new prosthetics. As the bone is often more fragile or has changed shape since the first operation, Dr David Kitchen uses dedicated revision implants designed for additional support and stability.
Is Revision Surgery Necessary?
A knee replacement may require revision for several clinical reasons. Dr David Kitchen identifies the underlying cause through blood tests and advanced imaging. These may be:
Implant Loosening where the bond between the implant and the bone can weaken over time and lead to pain.
Wear and Tear from the material liner can degrading, which may cause inflammation or bone loss.
Infection that is deep and around the prosthetic joint requires the components to be replaced for health.
Instability where damaged ligaments can cause the knee to feel unstable, requiring a more constrained implant.
Fracture or injury in the bone surrounding the existing implant.
Potential Benefits of Revision Knee Surgery
Pain Relief
Addresses the source of mechanical pain or inflammation from a loose or worn implant.
Joint Stability
Uses constrained implants and longer stems to provide a firmer foundation where ligaments or bone may be weak.
Bone Preservation
Uses modern augments and grafts to manage bone loss and support the new prosthesis.
Mobility
Helps improve the range of motion and weight-bearing capacity of the limb.
About the Surgery
Every revision surgery is individual to the patient. As the original implant is removed, any bone loss is addressed during the procedure.
Component Removal
The old components are carefully removed to keep as much bone as possible.
Bone Management
Dr David Kitchen may use metal augments or bone grafts to build a stable foundation.
Specialised Implants
Implants that feature longer stems that sit further inside the bone for increased load distribution.
Reconstruction
The new components are fixed in place and the joint is tested for alignment and tension.
Recovery & Rehabilitation
Day
1 - 4
Hospital Stay
Pain management and initial mobility focus. You will begin gentle exercises with a physiotherapist before discharge.
Week
1 - 6
Month
2 - 4
Functional Strengthening
Physiotherapy at our Stepney clinic intensifies to improve range of motion and muscle support around the new joint.
Month
6 - 12
Full Activity
Most patients return to low-impact daily activities, though complete healing of the bone and soft tissues continues for up to a year.
