A Total Knee Replacement is designed to provide long-lasting relief from pain and improved function. However, sometimes, a previously performed knee replacement may develop issues over time, leading to persistent pain, instability, or reduced mobility. In such cases, Revision Total Knee Replacement is a specialised and complex surgical procedure to replace or modify some or all components of the original implant. Mr. Raman Sethi is an experienced orthopaedic surgeon in Melbourne, proficient in performing complex revision total knee replacement surgeries, aiming to resolve challenging knee problems and restore your quality of life.
The need for a revision total knee replacement can arise for several reasons, often years after the initial surgery:
This is the most common reason, where the original implants become loose from the bone without infection, often due to wear debris or breakdown of the implant-bone interface.
The plastic (polyethylene) liner between the metal components can wear thin over time, leading to instability, pain, and sometimes bone loss.
A serious complication where bacteria infect the joint replacement. This often requires multiple surgeries, including removal of the old components and re-implantation of new ones.
The knee may feel unstable, give way, or dislocate, often due to ligament imbalance or implant malposition.
Sometimes, the implanted components themselves can cause pain or irritation.
A fracture occurring in the bone around the existing knee replacement.
Excessive scar tissue formation can severely limit knee motion.

Revision total knee replacement is generally more intricate and technically demanding than a primary knee replacement. It often involves:
The goal is to provide a stable, functional, and pain-free knee for the long term.
Recovery from a revision total knee replacement can be more prolonged and challenging than from a primary knee replacement.
Your commitment to the rehabilitation process is paramount for a successful outcome.
Mr. Sethi possesses the specialised surgical expertise and experience required to manage the complexities often associated with revision total knee replacements.
He employs thorough diagnostic workups to accurately pinpoint the cause of the previous knee replacement failure, ensuring the most appropriate revision strategy.
Whether it's aseptic loosening, infection, or instability, Mr. Sethi has the knowledge to address diverse and challenging revision scenarios.
Recognising the demanding nature of revision recovery, his team provides extensive support and guidance through a structured rehabilitation program to maximise your return to function.
Revision surgery is typically more complex. It involves removing older implants, addressing bone loss, dealing with scar tissue, and often using specialised, larger, or modular implants, leading to a longer and more challenging procedure and recovery.
The most common reasons include aseptic loosening (implants becoming loose without infection), wear of the plastic components, and infection of the joint.
Post-operative pain levels vary. While the surgery itself is more involved, modern pain management techniques aim to keep you comfortable. However, the overall recovery period for a revision is often longer and can be more challenging.
The longevity of a revision knee replacement can vary widely depending on the original problem, the patient’s age and activity level, and the success of the revision. While typically not as long as a primary replacement, many revision procedures provide years of successful function.
Yes, early mobilization is usually encouraged to prevent complications and aid recovery. However, the extent and timing of weight-bearing will depend on the surgical findings and Mr. Sethi’s specific instructions for your case.
