3D printed instruments made just for you
Different to a regular knee replacement, Dr Ward uses customised 3D printed surgical instruments to precisely align and prepare the knee to receive the knee prosthesis.
Dr Jason Ward will send you for a CT scan to allow planning for bespoke, customised 3D printed instruments specific to your knee. Dr Ward will utilise the CT scan to tailor a surgical plan and manufacture the instruments to allow that plan to be carried out precisely during your surgery. This 3D planning means that the prosthesis can be positioned to obtain the best possible result and functional outcome from the surgery.
When might patient-matched technology for knee replacement be suitable?
Patient-specific instrumentation (PSI) is a ground-breaking technology utilising modern 3D printing techniques. It allows detailed planning and for an individual approach for knee replacements. This may improve the knee replacement outcomes for many patients. It may not be suitable for everyone, but it may benefit you if:
You want to return to vigorous activities
Hiking, tennis or even downhill skiing may be possible after patient-matched technology for knee replacement. High-impact activities like basketball or soccer are not recommended after any knee replacement.
You are young
3D printing allows the instruments to fit the knee and surrounding structures more precisely. This allows detailed planning for your surgery, which may mean the knee prosthesis lasts longer, requiring fewer revision surgeries in the future.
How does patient-specific technology work?
Dr Jason Ward will refer you for an extensive CT scan involving images of your hip, knee and ankle. This allows specific analysis of the knee and assessment of the alignment of the overall leg. The scans are sent to a facility in Europe which uses those images and information to create the customised equipment.
Algorithms convert the scans to a 3D model, and a specific plan is formulated to manufacture instruments to match your existing bone structure.
After computer modelling to ensure optimal movement, as well as alignment for the knee, the equipment is manufactured then shipped to Dr Ward. These instruments, along with the implants are used by Dr Ward during the knee joint replacement operation.
The final implantation process is much the same as it is for a regular knee replacement. You can learn more about the surgery by visiting Dr Jason Ward’s knee replacement page.
Expected outcomes
The majority of patients report positive outcomes from knee replacement procedures. The use of patient-matched technology is an innovative technique that allows the prosthesis to be placed in the knee in a more accurate way, taking into consideration your unique anatomy.
Patient-matched technology for knee replacement is now available through Dr Jason Ward’s clinic. This technique is more expensive to produce, however most private health funds will cover the cost.
Is patient-matched technology right for your knee replacement?
Not all patients will receive significant benefit from having a patient-specific technique over a conventional one. If you wish to find out whether the procedure is your best option, book a consultation with Dr Jason Ward.
