Duke selected to participate in PEPPER trial: Largest Orthopaedic Trial Ever Conducted

adult reconWe are excited to announce that the Division of Adult Reconstruction at Duke has been selected as one of 25 institutions to participate in MUSC Health’s PEPPER (Pulmonary Embolism Prevention after Hip and Knee Replacement) trial, which is funded through a Patient-Centered Outcomes Research Institute (PCORI) award. The largest of its kind, the PEPPER trial’s goal is to combine information about effectiveness in preventing blood clots in the lungs and legs with the opinions of patients about the safety of the most commonly employed blood thinners. This work will provide background information to help both patients and their surgeons in deciding which blood thinner would be best to use after hip and knee replacement.

From MUSC Health:

Nearly one million total hip and knee replacements are performed each year in the United States. Because disturbing the bone marrow cavity turns on the blood clotting system in humans, these operations can be complicated by formation of blood clots in the veins of the leg (deep vein thrombosis). These clots sometimes detach from the leg veins and travel to the lungs (pulmonary embolism, PE) where they interfere with the normal pumping of the blood from the heart. When a large clot gets stuck in the lung, it can result in death. The use of blood thinners around the time of operation reduces the risk of PE, but increases the risk of bleeding from the raw bony surfaces that are created when the joint replacement is done. The ideal balance between use of blood thinners to prevent PE and the risk of bleeding associated with their use is unknown.

In order to generate enough data to achieve the purpose of PEPPER, approximately 25,000 patients undergoing elective total hip or knee replacements will be enrolled at 25 centers over a period of 3.5 years. The study will encompass five years, with six months startup, six months follow-up per patient, and six months for final data analysis. The principal investigator is Vincent Pellegrini, M.D, John A. Siegling Professor and Chair of the Department of Orthopaedics at the Medical University of South Carolina. Learn more about the PEPPER study.
