Tourniquet use in routine primary total knee arthroplasty is associated with a higher transfusion rate and longer postoperative length of stay: a real-world study.

摘要: In an enhanced recovery after surgery program, a growing number of orthopedists are reconsidering the necessity tourniquet use in total knee arthroplasty (TKA). However, impact on transfusion rate and postoperative length stay (PLOS) TKA remains controversial. Therefore, we carried out study to investigate effect application routine primary PLOS. We analyzed data from 6325 patients who underwent unilateral divided them into two groups according whether was applied during procedure, used 4902 not 1423. The information for PLOS extracted patients’ electronic health records, were with logistic linear regression analyses. Following TKA, 14.52% 7.72 ± 3.54 days, respectively, group, 6.47% 6.44 ± 3.48 days, no-tourniquet group. After adjusting different related variables, significantly correlated higher (risk ratio = 1.888, 95% confidence interval (CI) 1.449–2.461, P < 0.001) longer (partial coefficient (B) = 0.923, 95%CI 0.690–1.156, P < 0.001). Our findings suggested that should be taken account clinical practice.
