Review Outlines Surgical Options for Osteochondral Lesions of the Talus

A review in The Journal of Bone and Joint Surgery examines treatment strategies for osteochondral lesions of the talus, which remain challenging because durable hyaline cartilage is difficult to restore. Operative selection depends on lesion size and morphology, cartilage integrity, subchondral bone involvement, and ankle stability. The supplied overview does not report sample sizes or quantitative treatment effects.

Fragment fixation preserves the native osteochondral unit and is primarily indicated for acute lesions with a viable fragment. Lift-drill-fill-fix may be used in selected chronic lesions with salvageable fragments and compromised subchondral bone. For small, contained lesions, bone marrow stimulation techniques—including microfracture and drilling—have improved pain and function, although the durability of fibrocartilaginous repair varies.

Autologous osteochondral transplantation and osteochondral allograft transplantation have shown favorable outcomes for larger or structurally complex lesions. Cell-based and matrix-assisted techniques have also improved clinical outcomes and cartilage repair in selected patients. Scaffold-based repair, osteoperiostic autografting, and biologic adjuncts such as concentrated bone marrow aspirate, platelet-rich plasma, and hyaluronic acid have encouraging early results, but supporting evidence remains limited.

For extensive lesions or failed prior surgery, salvage options include bulk allograft transplantation, metallic resurfacing, hemiarthroplasty, and arthrodesis. Outcomes remain variable, with high complication and failure rates. The overview supports tailoring treatment to lesion characteristics but provides no quantitative comparative estimates to establish superiority among approaches.
