A surgeon requires data to make objective decisions intraoperatively. The subjective art of knee arthroplasty has shown to be poorly translatable. We can only compare our outcomes with integrated data from the patient鈥檚 preoperative evaluation, linked to real-time intraoperative data regarding optimal knee balance and alignment, and the effect of these variables in the postoperative recovery. The data that is provided from the single use VeraSense sensor enables surgeons to compare just that.

VeraSense improves the surgeon鈥檚 ability to achieve soft tissue balance while performing a  total knee arthroplasty (TKA).1-8 Multiple studies, including a multicentered blinded control trial, have confirmed that a balanced knee leads to an accelerated recovery, as well as improved patient outcomes and satisfaction.1-3, 9-11 This has also translated into fewer postoperative resources utilized, resulting in cost savings for the system.11-12

Robotic-assisted TKA improves a surgeon鈥檚 ability to execute the preoperative plan with safety through haptics, with consistent, accurate bony cuts.13-15 Patients are experiencing less pain16-17 and improved outcomes scores have been published.17-19

These integrated technologies turn surgical instruments into smart tools that provide real- time, actionable data. The utilization of robotic and sensor-assisted technology will become the standard in knee arthroplasty as we can now functionally place our implants to achieve optimal soft tissue balance and alignment. It will enable surgeons to achieve similar outcomes irrespective of their experience and customize the procedure to each patient鈥檚 pathologic condition.

As we strive to develop intelligent approaches to knee arthroplasty, sensor-assisted technology like VeraSense provides healthcare providers globally with evidenced-based data that improves clinical and economic outcomes for patients and healthcare stakeholders.
