[The Influence of Tourniquet during Total Knee Arthroplasty on Perioperative Blood Loss and Postoperative Complications].

Background: Previous studies have shown that tourniquet (TQ) during total knee arthroplasty (TKA) is associated with nerve injury and deep vein thrombosis. However, it is still not clear whether TQ which is effective in decreasing intraoperative blood loss and creating a bloodless surgical fields, is beneficial in management during and after TKA.

Methods: We compared intra- and postoperative management of patients undergoing TKA with (Group T, n = 41) and that without a TQ (Group N, n = 40) at Toyama Prefectural Central Hospital.
