There was no significant difference between the two groups in terms of revision rate based on the meta-analysis results and retrospective cohort. CAOS improves the accuracy of the coronal femoral/tibial component alignment, but the clinical outcomes and the occurrence of complications including revision are similar. CAOS is not considered cost-effective compared with the conventional TKA because the QALYs gained were small and the extra cost required too much in Korea. Cost-savings is achieved if the added cost of CAOS is KRW 30-40 thousand or less per operation. However, we considered only 5-year follow-up after TKA; an expanded study with 10-15 years follow-up is required to determine the long-term cost-effectiveness.
