2021 Annual Meeting Foot & Ankle Access Pass-Outcomes of Bone Marrow Stimulation With and Without Extracellular Matrix Cartilage Allograft

Outcomes of Bone Marrow Stimulation With and Without Extracellular Matrix Cartilage Allograft

Video Transcription

Video Summary

In this video, Owen Hurley discusses bone marrow stimulation as a treatment for osteochondral lesions of the talus. He explains that bone marrow stimulation releases bone marrow stem cells to the defect, allowing fiber cartilage to form. However, this cartilage is susceptible to deterioration over time. The use of extracellular matrix cartilage allograft (EMCA) has been explored as an adjuvant treatment, as it contains growth factors native to cartilage. A retrospective study was conducted comparing bone marrow stimulation alone to bone marrow stimulation with EMCA. The study found no significant difference in clinical function scoring between the two groups, although there were some significant differences in subcategories of the MoCART score. The study acknowledges limitations such as differences in follow-up times and prior bone marrow stimulation. In conclusion, bone marrow stimulation with EMCA improves cartilage infill but does not translate to improved functional outcomes in the short term.
