289 Blood Loss in Robotic-Assisted Knee Arthroplasty: A Retrospective Analysis

Abstract Introduction Significant blood loss is associated with a delayed postoperative recovery in joint arthroplasty. Emerging evidence suggests robotic-assisted knee arthroplasty reduces soft-tissue trauma, length of stay, and can facilitate faster recovery. This study compares the total patients undergoing compared to conventional methods. Method Patients (TKA) or unicomparmental (UKA) were identified using patient records. Robotic-assisted groups against contemporary sex-matched controls jig-based The mean was estimated Gross equation. Statistical significance Student's t-test Mann-Whitney U test for parametric non-parametric data, respectively. Results Robotic TKA UKA successfully matched (n = 50 all groups).
