Abstract

Introduction Methods Results Conclusions Levels of Evidence This study provides an in‐depth analysis of the immediate postoperative outcomes and implications or robotic‐assisted total knee arthroplasty (RA‐TKA) compared with conventional TKA (C‐TKA), particularly with regard to mortality, complications, hospital stay and costs, drawing from a comprehensive nationwide data set.The Nationwide Inpatient Sample (NIS) database, the largest all‐payer inpatient healthcare database in the United States, was used to identify all patients who underwent RA‐TKA or C‐TKA from 2016 to 2019. A total of 527,376 cases, representing 2,638,679 patients who underwent elective TKA were identified, of which 88,415 had RA‐TKA. To mitigate potential variations and selection bias in baseline characteristics between the two groups, a propensity score‐matched analysis was employed to further balance and refine our data set, resulting in 176,830 patients evenly distributed between the groups. Analysis was performed according to demographics, immediate post‐operative complications, and economic data, including payor class, length of stay and total charges.There was a marked shift towards RA‐TKA, from an initial 0.70% in 2016 to a notable 7.30% by 2019. Patients who underwent RA‐TKA were slightly younger (66.2 ± SD years), compared to the C‐TKA group (66.7 ± SD years). Hospital stay was 1.89 days and 2.29 days for RA‐TKA and C‐TKA, respectively. Charges metrics revealed slightly higher charges for RA‐TKA. Less postoperative complications were found in the RA‐TKA group, such as blood loss, anaemia, acute kidney injury, venous thromboembolism, pulmonary embolism, pneumonia and surgical wound complication. Even following the propensity score matching, these findings remained consistent and statistically significant.RA‐TKA use in the United States has grown substantially in the last few years and has been associated with significantly reduced immediate post‐operative complications and length of hospital stay compared to C‐TKA, offering safer surgical management for TKA patients. Further studies on the short‐ and long‐term outcomes of RA‐TKA would improve the understanding of the full potential of this technology.Level III. [ABSTRACT FROM AUTHOR]
