Limit the bleeding, limit the pain in total hip and knee arthroplasty.

Patients undergoing total hip or knee arthroplasty often sustain significant decreases in hemoglobin and hematocrit, despite modern techniques and shorter operating times. Reasons for the blood loss include raw bony surfaces, vascular inflammatory tissue, and fragile vessels in elderly patients. Acute postoperative anemia has numerous deleterious effects on patients, including delayed rehabilitation, exposure to allogeneic blood transfusions, higher complication rates, and increased pain. The ability to limit the amount of postoperative bleeding may reduce the amount of postoperative pain that patients experience, ultimately resulting in greater patient satisfaction and smoother postoperative rehabilitation. This article focuses on intraoperative techniques available to limit bleeding, thereby minimizing pain and the need for postoperative transfusion.
