Studies have been made on the best way to do knee surgery and whether to conserve the posterior cruciate ligament or not during total knee prosthesis insertion is still under debate. However, most of these studies were made before the introduction of robotic knee surgery. It seems timely to do a study comparing these two surgical techniques: preservation versus removal of the posterior cruciate ligament in knee arthroplasty
