摘要

Degenerative musculoskeletal disorders are one of the top causes of pain and disability in the adult population.Current available alternatives to mitigate symptoms include conservative treatments such as the administration of pharmacological agents and an educative approach towards lifestyle modification.The use of certain analgesics,such as opiates and corticosteroids,delivers short term results but do not address the etiological source of pain and disability.Also,prolonged use of such medications may cause additional complications.Therefore,the demand for musculoskeletal tissue regeneration has led to an alternative approach referred to as“orthobiologics”.This alternative is based on cellular and molecular components capable of inducing and promoting tissue repair.Bone marrow(BM)aspirate(BMA)and concentrate are well-known orthobiologics used to treat musculoskeletal conditions.Orthobiologics derived from the BM have been discussed in the literature;however,the lack of standardization regarding collection and processing protocols presents a challenge for generalization of study outcomes and determination of efficacy.Since BM-derived orthobiologics have not yet been classified,to our knowledge,this manuscript proposes the ACH classification system,which speaks to BMA(A),BMA and concentrate(C)and hybrid(H),which combines A and C.This classification proposes and describes 8 parameters that are relevant for the quality of biological products.The more parameters used would imply greater characterization and complexity of the evaluation of the biological product used.The ACH classification envisages a necessary contribution to the comprehension of both clinical procedures and research outcomes,ultimately ushering in a standardization of best practice.
