Frequently asked questions
Is Knee+ easy to integrate into my surgical workflow? Does Knee+ NexSight change my surgical technique?
Knee+ NexSight only involves AR glasses running dedicated software and reusable surgical instruments, which makes it simple to integrate. There is no new surgical technique to learn. Set-up takes only a few minutes and does not depend on a…
What are the benefits of Knee+ for knee replacement surgery?
Knee+ NexSight helps your surgeon place your knee implant more accurately than standard knee replacement surgery, based on your own anatomy, which may help support a smoother recovery and potentially improve long term outcomes. (According to a study on…
How is this different from the other options?
With a standard knee replacement, the surgeon typically uses mechanical instruments, including a long metal rod inserted inside the femoral canal. With Pixee, this rod is not needed. Instead, your surgeon wears augmented reality glasses that show real-time guidance…
What are the advantages of Knee+ NexSight compared to a surgical robot or conventional arthroplasty?
Compared to conventional instrumentation, Knee+ NexSight removes the need for an intramedullary rod, is associated with less blood loss, and delivers robotic-level precision, all without a significant difference in operative time. Compared to a surgical robot, Knee+ NexSight…
How can I purchase Knee+ NexSight?
Knee+ NexSight is not sold through a public price list or online store. To purchase the system, contact the Pixee Medical team directly through the contact form on the website.
Does Knee+ require preoperative imaging (X-ray, CT scan)?
No. Knee+ NexSight does not require preoperative imaging such as an X-ray or CT scan. The surgeon plans and adjusts the bone cuts directly during surgery, based on the patient’s actual anatomy and clinical parameters.
Does Knee+ require a large capital investment or service contract like a surgical robot?
No. Unlike a surgical robot, Knee+ NexSight does not require a major capital investment, and there are no service contract or maintenance fees to worry about. The system is available through a pay-per-use model, where surgeons purchase usage credits,…
Does Knee+ require any setup or installation time before total knee replacement (TKR) surgery?
Knee+ NexSight requires only a few minutes of preparation and does not depend on a sales representative to be set up or operated during surgery. The surgical team simply lays out the reusable surgical tools on the table, as…
Can Knee+ be used with different implant placement philosophies?
Knee+ NexSight can be adapted to the surgeon’s workflow, therefore not forcing a surgeon to change how they perform the surgery.
Is a training required for surgeons? How quickly can surgeons learn Knee+ NexSight?
Surgeons receive on-site support from the Pixee Medical team to learn the system, and this support continues until the surgeon reaches full autonomy.
Can I use Knee+ NexSight with my preferred knee implant, or am I locked into a specific brand?
Yes. Knee+ NexSight is implant-agnostic and works with all primary total knee implant systems, so surgeons keep using the implant brand they already trust. Guidance accuracy stays the same regardless of the implant selected, and no changes are needed…
What clinical evidence supports Knee+? Is it FDA cleared? Is it CE marked?
Knee+ NexSight is FDA cleared and CE marked. Its accuracy and safety are supported by more than 11 published clinical studies, covering over 15,000 surgeries performed with the system to date. Full study references are available on the…
Does Knee+ NexSight increase surgical operating room (OR) time?
Studies have shown that Knee+ is either time neutral or adds a minimal amount of time to the total surgery. This system does not involve any appreciable setup or breakdown time, therefore not increasing the total time of surgery.
How accurate is Knee+ NexSight during total knee replacement surgery?
Knee+ NexSight delivers robotic-level precision, combining accurate digital guidance with real-time cut validation throughout the procedure. For detailed accuracy data, refer to the published studies in our Education and Research page, particularly Lambrechts et al. and Dossett et…
Is Knee+ NexSight suitable for me?
Knee+ NexSight is designed for use in primary total knee replacement surgery. More than 15,000 patients have already had their knee replacement surgery with Knee+ to date. Whether Knee+ is the right fit for your specific case is a…
