“…Studies have shown that this method provides healing with fibrocartilage tissue that is histologically and biomechanically below normal hyaline cartilage [ 13 , 14 ]. Therefore, various attempts have been made to improve the outcome of these microfractures, including adding (augmenting) natural biological substances, such as intra-articular MSC, platelet-rich plasma (PRP), platelet-rich fibrin (PRF), scaffold and others as adjuvants [ 9 , 15 ]. The combination of microfractures and biologics can promote the healing to hyaline-like cartilage [ 16 ].…”
