With the VISIONAIRE system, a surgeon uploads each patient's specific MRI and X-Ray images into Smith & Nephew's proprietary web-based software. A Smith & Nephew engineer then uses this data to design and build customized surgical instruments that accommodate the unique shapes and angles of each patient's joint for a more precisely aligned implant.
According to the JOA study, surgeries that used patient-matched instruments resulted in implants that were a full degree closer to neutral – the body's natural alignment – than those using traditional instrumentation. The accurate placement of an implant has been shown to reduce implant wear and improve the longevity of an implant.[i]
Additional key findings in the study are that patient-matched technology:
- Reduces the amount of time a patient spent under anaesthesia;
- Shortens a patient's hospital stay;
- Shortens the length of the incision required for knee replacement surgery.
