I used nav in 2005 and was looking forward to robotics when they came on the scene. First it was Mako and now Rosa and Velys. Unfortunately, the powers that be have not allowed them in our system yet.
I think it is important for residents and fellows to be trained with robots. It is a part of education today. Robotic training will help you land a job. Robotics may help you attract patients.
Augmented reality may offer some of the same information because that technology is advancing quickly.
But, you need to know how to do a manual total knee well. A robot may not be available. Software may be corrupt or fail. Garbage in, garbage out. If it doesn't look right or feel right do not just believe what you see on. a screen or a heads-up display. You need reps on manual total knees so you have a bailout if things don't work with the technology.
