iASSIST Knee Improves on Previous Navigational Technology
The main component of the iASSIST Knee is a disposable device that can be used as needed; no capital equipment investment by the hospital is necessary.
- Designed to intuitively integrate with surgeons’ conventional instrumentation for total knee arthroplasty
- No pre-operative imaging
- No wait time for the patient and the hospital
- Less invasive procedure to the patient
Unlike prior navigation technology or robotic surgery, the iASSIST Knee system saves surgeons more time, hospitals additional costs by eliminating pre-operative imaging, and is less invasive for the patient with the absence of additional incision for pins fixation.
More importantly, the iASSIST Knee has the ability to validate bony cuts intra-operatively, which allow the surgeon to target a greater level of accuracy.
Dr. Camarata describes the system with these words: “[When using iASSIST Knee] the surgeon can be confident that there will be no outliers or bony cuts that are out of alignment. I have never used traditional navigation, yet I was able to adapt this technology immediately for my patients with no down time”. 1
