Pneumatic tourniquets are commonly used in total knee arthroplasty (TKA) to reduce intraoperative blood loss, enhance operative visualization, provide a cleaner field for cement penetration and fixation, and increase operative efficiency. However, the use of tourniquets during TKA has been a subject of debate in the scientific literature due to the risks and benefits associated with their use.
While pooled analyses consistently show less intraoperative blood loss with a tourniquet, they also point to a greater likelihood of thrombotic events, wound problems, and minor complications. Furthermore, several studies have demonstrated that tourniquets result in greater pain in the immediate postoperative period after TKA, with some studies additionally noting an increase in analgesic consumption.
