Abstract

This study assessed the impact of adding computer-assisted orthopedic surgery (CAOS) augmentation to conventional mechanical instrumentation with regard to the enablement of both mechanical and natural alignment surgical philosophies and accuracy of postoperative alignment for total knee arthroplasty (TKA). 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
