Bone marrow-derived fibrin clot is better source for meniscal repair
With age, the meniscus receives less and less blood—with the inner most area becoming avascular. Tears in this area do not heal normally, often requiring surgery. Surgeons can draw fibrin, a protein involved in blood clotting, from peripheral blood (PB) or bone marrow aspirate (BMA), and implant a fibrin blood clot into the injured area to help with healing.
