It was reported that as soon as distal femur cutting started, handpiece homing and internal mechanical error presented.
Calibration was done 3 times and passed once but homing failed.
All internal connections were checked and failure continued.
Handpiece was swapped with a different one to continue the case.
Delay of less than 30 minutes was reported and no patient impact or injury was involved.
Investigation results determined that connectivity issue at the handpiece end of the cable.
The internal wiring at that end had come apart in the cable caused a short in the wiring, which makes it a reportable event.
