Concentrated Bone Marrow Aspirate (CBMA) for Osteochondral Talus Lesions: Promising but Inconclusive

We all want an effective approach to improve outcomes with osteochondral lesions of the talus. CBMA, rich in stem cells and cartilage-promoting factors, has emerged as a potential solution, but clinical evidence remains limited.

A systematic review of 15 studies (PubMed, Scopus, Cochrane) examining functional and pain outcomes after CBMA-assisted surgical treatment of osteochondral talus lesions in adults. 

CBMA improved pain and function across multiple applications – standalone, with debridement, and alongside repair techniques – but results were inconsistent, and cartilage imaging scores were mixed.

Evidence falls short

CBMA shows promise as an adjunct treatment, but the current evidence doesn’t support the mic drop moment that allows us to promote it as a primary strategy.
