Early Experience with CAOS Enhanced Total Knee Arthroplasty – A Global, Multi-surgeon Evaluation

Abstract

This study investigated surgeons’ perceptions of their experience while adopting a novel CAOS enhanced mechanical instrument system for TKA, including ease of usage, task complexity, and demands of surgical time and physical activity. A group of 9 surgeons from multiple countries with no experience in the investigated system used the CAOS enhanced mechanical instrument system during their surgical practice. After performing each TKA case, the surgeon independently completed a 6-section questionnaire formulated to survey his/her experience with the case. The results demonstrated high level of surgeons’ experiences with the adoption of the CAOS enhanced conventional instrumentation, with particularly satisfying experiences in minimum demand of time in landmark acquisition and disruption of the existing surgical process.

Total Knee Arthroplasty with CAOS Augmentation

“…A recent technology added CAOS augmentation to conventional mechanical instruments, removing the need for significant instrument learning. The system has been shown to have minimal learning curve [2] and offer good usability and demonstrated to be non-disruptive to the surgical flow during its early adoption, reported by a subjective survey by the users [3].…”
