Basic Science of Meniscus Repair: Limitations and Emerging Strategies
Fig. 10.1 Schematic of a horizontal meniscal tear highlighting the limitations to repair (hypovascularity, hypocellularity, and inflammation) and pro-repair strategies, including enhancing vascularity (angiogenesis, fibrin clot, vascularized graft or conduit),…
Biological Augmentation of Meniscus Repair and Restoration
