Osteochondral lesions of the ankle: The current evidence supporting scaffold-based techniques and biological adjuncts.

BACKGROUND

Talar osteochondral lesions are more common than has been previously recognized. Optimal treatment remains unclear and the subject of much debate in the literature. Although reparative techniques such as microfracture have produced initial good results and remain the gold standard in the management of these lesions, the literature is deficient in long-term data. Recently, techniques focused on enhancing the local biological environment have been developed which have demonstrated promising outcomes.

METHODS

We reviewed the available evidence concerning scaffold-based techniques and biological adjuncts in the management of talar osteochondral lesions published in the English language on PubMed.

RESULTS

An update is provided on the current evidence concerning the role of biological adjuncts in the management of osteochondral lesions of the talus.

CONCLUSIONS

There has been an explosion of interest among the orthopaedic community in the role of biologics in the management of complex talar osteochondral lesions. A number of exciting new techniques have been developed which show promise. Robust randomized control trials are required to identify the optimal surgical strategy.
