Abstract

This study investigated the accuracy of a novel CAOS enhanced mechanical instrument system for TKA, and its sensitivity to surgeon’s experience level. Resection errors in varus/valgus alignment were assessed across senior, fellow, and resident surgeon groups, and compared between CAOS guided resections and resections performed with conventional instruments. The findings demonstrated that regardless of surgeon experience level, the CAOS enhanced mechanical instrumentation significantly reduced alignment errors compared to conventional instrumentation, along with substantial increases in the prevalence of optimal resections.

Keyphrases: alignment accuracy, caos enhanced mechanical instrument system, surgeon experience level, total knee arthroplasty
