Editorial Commentary: Considering Clinical Application of Bone Marrow Aspirate Concentrate for Restoration of Cartilage Defects in the Knee? Is It a Kind of Stem Cell Therapy?

Abstract

The role of bone marrow aspirate concentrate (BMAC) is still inconclusive for restoration of chondral defects in lesions of the knee. More investigation is needed; thus, clinical application of BMAC for chondral defects should be considered cautiously. Correct nomenclature of the entity of cells used in various stem cell therapies for the treatment of cartilage lesions is critical to properly assess the efficacy and safety of various stem cell therapies. Constant effort is needed to prove the therapeutic potential of various novel therapeutic options such as BMAC or stem cell therapy under correct terminology for cartilage restoration before routine clinical application.
