Short term outcomes of long duration versus short duration tourniquet in primary total knee arthroplasty: A randomized controlled trial

The use of a short duration tourniquet during TKA gives better symptomatic pain relief in the early postoperative period as compared to long duration use of tourniquet. However, this is associated with increased blood loss, more operating time and not having a clear operative field. We suggest that a rational thinking and reconsidering the practice of routine use of long duration tourniquet in each and every case of TKA is required.
