Impact of body mass index on robotic-assisted total knee arthroplasty outcomes: A retrospective cohort analysis

Abstract

INTRODUCTION: Obesity is a growing global health concern and a known risk factor in total knee arthroplasty (TKA). With an increasing number of obese patients requiring TKA, it is essential to understand how obesity influences clinical outcomes and complication rates. The objective of this study is to investigate the impact of obesity on clinical outcomes and complications in patients undergoing robotic-assisted TKA (RA-TKA). METHODS: . Demographic, intraoperative, and postoperative variables-including tourniquet use and time, implant type, hospital stay, and complications-were compared. Statistical analysis was performed (p < 0.05). RESULTS: group (18.2% versus 7.2%), though the difference was not statistically significant (p ​= ​0.09). CONCLUSIONS: , a finding that contrasts with the current literature. LEVEL OF EVIDENCE: Level III.
