A new robotic device led to placement of unicompartmental knee arthroplasty implants matched to the patient's anatomy that exceeded the accuracy of placements involving traditional procedures and components, according to results of a pilot study presented at the British Orthopaedic Association Congress 2012, here.
Preoperatively surgeons made operative plans for all these cases using input from CT scans that guided component position, orientation and selection of component size. Intraoperatively the surgeon holds the burr used to remove bone, but the robot provides haptic and visual feedback, Andrews said.
