The Use of Bone Marrow Concentrate in the Treatment of Full-Thickness Chondral Defects.

This article is a critical analysis of a study, "Minimally Manipulated Bone Marrow Concentrate Compared with Microfracture Treatment of Full-Thickness Chondral Defects: A One-Year Study in an Equine Model," by Chu et al. (. 100(2):138-146, 2018). The investigation compared two interventions in the management of full-thickness chondral defects in an equine model: autologous bone marrow concentrate without concomitant microfracture treatment versus microfracture treatment alone. This review analyzes the methodology and results of their investigation and examines how their findings may influence the continued development of therapeutic options for full-thickness cartilage injuries. The study utilized in vitro analysis, arthroscopic assessment, magnetic resonance imaging (MRI) evaluation, and histological analysis to compare the treatments and their influence on the quality of cartilage repair. Although Chu et al. reported similar results between groups, their findings offer insight into the role of arthroscopy, MRI, and histology in the evaluation of repair quality. We compare their findings to those of similar investigations, highlighting the limited therapeutic options and variable clinical outcomes related to the treatment of full-thickness articular cartilage defects.
