It was reported that during a cori tka procedure, the first robotic drill could not seat the bur in the carriage.
They swapped to another robotic drill that did not seem to mill as it should, even though they did not receive any errors.
It did not appear to be cutting bone efficiently.
The bone was very hard and the surgeon moved between making saw cuts and cleaning up cuts with bur, but it did not appear to cut much.
There was a change to manual procedure and a delay greater than 30 minutes.
No other complications have been reported.
