Background: The use of the pneumatic tourniquet (PT) in total knee arthroplasty (TKA) has been controversial; its advantages, disadvantages and associated complications have been described. In order to assess its benefits we analyzed operative time; intraoperative, postoperative and total bleeding volume, as well as pre- and postoperative hemoglobin and hematocrit values in patients who had undergone primary TKA using the PT, and they were compared with a control group. Material and methods: A retrospective analysis of the clinical records of cases who underwent TKA was conducted. Based on the inclusion criteria and the use or non-use of PT, two groups were formed: a study group (n = 19) and a control group (n = 19). The following variables were compared: operative time, intra and postoperative bleeding and total bleeding; initial and final hemoglobin and hematocrit values. Results: Significant differences in favor of the group with PT use were obtained in 7 out of the 8 variables studied. The most relevant ones were operative time (t = 2.08 p < 0.050); intraoperative bleeding (t = -6.44, p < 0.010); postoperative bleeding (t = -2.170 p < 0.050) and total bleeding (t = /7.52, p < 0.010). Conclusions: The results showed that patients in whom PT was used during TKA had a shorter operative time, and their total, intra- and postoperative bleeding and the estimated blood loss were lower than in controls. Additional suppositions on the benefits of PT warrant the conduction of more prospective research studies.

    This study reports the results of the clinical use of a new tourniquet system for surgery related to knee joint that can determine tourniquet pressure in synchrony with systolic blood pressure (SBP). We prospectively applied additional pressure of 100 mmHg based on the SBP recorded just before...
