Abstract

This study employed an advanced method (CUSUM) to analyze the learning curve regarding surgical efficiency (time) in 10 surgeons from different experience levels upon their adoption of a contemporary CAOS TKA system. The first 50 CAOS TKA cases of each surgeon were analyzed to identify the case number when their learning process was stabilized (cases of proficiency). The surgical time increase during the learning phase were compared between senior and novice surgeons. The data demonstrated a short learning duration (12-13 cases) and a moderate learning process (~15min time increase compared to later cases) upon adoption of the CAOS system, without high sensitivity to surgeon’s experience level.
