A total knee replacement is a highly successful procedure that provides relief from chronic knee problems, allowing individuals to lead a pain-free life. However, in some cases, the original knee replacement may fail to function correctly, resulting in persistent pain, swelling, and difficulty performing everyday tasks. In such situations, patients may require a second operation called complex revision knee replacement, which involves removing and replacing some or all of the original implant components with new ones.
Revision surgery is a more complex operation that requires expertise, thorough planning, and specialised tools and implants.
Prof Munjed Al Muderis has extensive experience with thousands of knee surgeries and has achieved unmatched and extremely low complication and infection rates. Patients can request the professor’s data from the Australian Orthopaedic Association National Joint Replacement Registry (AOANJRR) or the data of any other surgeon they may be considering for their care.
The decision to pursue a complex revision total knee replacement should be made after a thorough evaluation by a healthcare professional, taking into account the individual patient’s specific medical history, condition, and overall health.
Patients considering complex revision total knee replacement should have a thorough discussion with their healthcare provider to understand the potential benefits and risks, with decisions based on their individual medical history and the nature of their knee condition.
At our clinic, we employ a technology-driven approach, advanced imaging, CT scans, and 3D technology to create the best-fitting implants for each patient. We aim to provide the highest quality implementation using 3D modelling and printing technology to guide us.
A revision knee replacement is a more complex operation than a primary total knee replacement, requiring more time.
Anaesthesia is given either locally or general, for the patient’s safety and comfort.
The surgeon begins by following the incision line from the patient’s initial knee replacement surgery. In some cases, the incision may need to be lengthened to facilitate the removal of the original components.
The knee joint is checked for any signs of infection or adverse reactions to the metal components. The condition of the existing implant is inspected for wear and tear, loosening, or movement. Implant is then removed, together with cement, preserving as much bone tissue as possible. It is a time-consuming and meticulous process.
In some cases, there may be a significant lack of bone in the knee area due to complications from the previous surgery. To address these bone deficiencies, the surgeon may add metal augments and platform blocks to the main components of the revision implants.
Lastly, the surgeon will insert specifically tailored revision implants based on the 3D modelling conducted by the surgical team before surgery. This personalised approach ensures a precise fit of the implant to the individual patient and a better outcome.
Once the revision implants are in place, the surgeon carefully evaluates the joint motion to ensure that the implants are securely positioned. Special screws may be used to stabilise the fresh components until the bone fully grows around them.
If patients are worried about their level of pain, experience significant bleeding, or notice fever or redness around the surgical site, they should contact the office immediately. If assistance is needed after hours, patients can contact the hospital where the surgery was performed, and they will contact Professor Al Muderis on their behalf.
