So, you finally got a robot in your OR. Maybe it’s a MAKO, a ROSA, or even one of those underdog platforms like Velys or CORI. It stares at you from the corner like a high-tech intern—ready to assist, maybe outshine, and definitely judge. But here’s the reality check: you’re not a robotic TKA Jedi just because the machine is shiny.

According to a new meta-analysis in the July 13, 2025, Journal of Experimental Orthopaedics, you’ll need to perform somewhere between 15 and 40 robot-assisted knee replacements before you stop sweating bullets mid-cut. That’s right—there’s a learning curve, and it’s no joke.
