Effectiveness of Robotic Arm-Assisted Total Knee Arthroplasty on Transfusion Rate in Staged Bilateral Surgery

The transfusion rate in staged bilateral total knee arthroplasty (TKA) remains high despite the application of blood management techniques. potential robotic arm-assisted TKA (R-TKA) reducing surgery has not yet been investigated. Therefore, we aimed to evaluate effectiveness R-TKA on reduction compared with conventional (C-TKA) surgery. This retrospective study involved two groups patients who underwent 1-week interval TKA—the C-TKA group and group—using MAKO SmartRobotics (Stryker, Kalamazoo, MI, USA). Each comprised 53 after propensity score matching was terms nadir hemoglobin (Hb) level each stage Both showed no significant differences propensity-matched variables age, sex, body mass index, American Society Anesthesiologists physical status score, preoperative Hb level. a significantly higher than second (p = 0.002). different between first 0.558).
