Fifty CAOS augmented TKA cases were compared to 101 conventional cases. Data on surgical time, length of stay, and postoperative weight-bearing long leg alignment were collected. The results reported no significant impact on surgical time with incorporation of CAOS augmentation into the conventional surgical workflow, as well as a shorter length of stay and substantial decrease in alignment outliers compared to the conventional TKA cases. The study revealed the advantages of CAOS augmentation in providing a non-disruptive tool to enhance surgical accuracy and offer versatility in accommodating different surgical philosophies during TKA.Keyphrases: caos augmentation, preferred surgical philosophy, resection accuracy In: Ferdinando Rodriguez Y Baena and Fabio Tatti (editors).
