ABSTRACT

Introduction: total knee arthroplasty (TKA) is the treatment of choice for advanced osteoarthritis. Being a major procedure, prolonged surgical times and blood loss are the primary complications. Viable options to reduce these risks include pneumatic ischemia and tranexamic acid (TXA), but their comparative effectiveness remains inconclusive. Objective: compare surgical time in TKA in geriatric patients by evaluating the influence of pneumatic ischemia and TXA. Material and methods: a retrospective study was conducted on 81 patients aged ≥ 60 years who underwent TKA at Hospital Angeles Mocel. Patients were divided into two groups: one with pneumatic ischemia and the other with TXA. Surgical and anesthetic times, blood loss and postoperative outcomes were analyzed. Results: compared to the ischemia group, the TXA group showed shorter surgical times (100 versus 140 minutes, p = 0.008) and shorter anesthesia durations (115 versus 167.5 minutes, p = 0.003). Blood loss was also lower in the TXA group (156 versus 289 mL, p = 0.025). Postoperative hemoglobin and hematocrit levels were better preserved in the TXA group. Conclusion: the TXA group reduced surgical times, leading to shorter anesthesia durations and a positive impact on blood loss, which was lower in this group.
