AI Article Synopsis
- The study aimed to identify the most reliable method for calculating blood-loss in patients following total knee arthroplasty (TKA).
- Various calculation methods (Gross equation, Hb balance, OSTHEO formula, and Hb-dilution) were compared among 245 TKA patients, revealing significant differences in blood-loss estimates.
- The Hb-balance method demonstrated the highest correlation, suggesting it is the most dependable method for evaluating blood-loss after TKA.
Article Abstract
Background: Currently, various calculation methods for evaluating blood-loss in patients with total knee arthroplasty (TKA) are applied in clinical practice. However, different methods may yield different results. The purpose of this study was to determine the most reliable method for calculating blood-loss after primary TKA.
Methods: We compared blood-loss in 245 patients who underwent primary unilateral TKA from February 2010 to August 2011. We calculated blood-loss using four methods: Gross equation, hemoglobin (Hb) balance, the Orthopedic Surgery Transfusion Hemoglobin European Overview (OSTHEO) formula, and Hb-dilution. We determined Pearson's correlation coefficients for the four methods.
Results: There were large differences in the calculated blood-loss obtained by the four methods. In descending order of combined correlation coefficient based on calculated blood-loss, the methods were Hb-balance, OSTHEO formula, Hb-dilution, and Gross equation.
Conclusions: The Hb-balance method may be the most reliable method of estimating blood-loss after TKA.
