Allowing Strides in the Right Direction: Innovations in Total Knee Arthroplasty

In the latest issue of the Ochsner Journal, Rosenstein and colleagues present research on a procedural method that reduces blood loss during total knee arthroplasty and has minimal postoperative complications.

In the past, tourniquet use during total knee arthroplasty has proven mostly effective in reducing intraoperative blood loss, decreasing operative time, and increasing visualization during surgery but has caused problems for patients postoperatively. Tranexamic acid has also been used to decrease blood loss.

In “Benefits of Limited Use of a Tourniquet Combined With Intravenous Tranexamic Acid During Total Knee Arthroplasty,” Rosenstein and colleagues look at a tourniquet use and tranexamic acid combination. Their retrospective single-institution study showed that using tranexamic acid and using a tourniquet only during cementation provided the optimal benefit—decreased blood loss and reasonable operative time without increasing postoperative morbidity or complications.

Despite the study’s limitations, these findings are a useful continuation of the effort to maximize the success of total knee arthroplasty, a surgery that has doubled in performance within the last 2 decades.
