Total knee arthroplasty: Robot-assisted total knee arthroplasty
Study summary
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

Primary outcome measure(s)
Functional impact at of posterior cruciate ligament preservation in the LCP+group — 12 months post-surgery Evaluated according to the FJS-12 (Forgotten Joint Score) self-questionnaire. The FJS-12 is a self-administered questionnaire consisting of 12 items.
The patient is asked to rate their awareness of their artificial joint for the 12 activities. Each item is then given a score of between 0-4 on a five-point Likert scale in which : 0 - Never,1 - Almost Never, 2 - Seldom, 3 - Sometimes,4 - Mostly.
The answers are then summed and divided by the number of completed items. The mean value is then multiplied by 25 to obtain the total score of 0-100. The higher scores indicating better outcomes (less awareness of the joint).
