Foot and Ankle Arthroscopy: Latest and Emerging Techniques by the Leaders! (AANA22)-Osteochondral Lesions of the Talus

Video Transcription

Video Summary

The discussion focuses on osteochondral lesions of the talus, emphasizing treatment choice based on lesion size, subchondral cysts, location, and containment. Microfracture is effective for lesions under ~107 mm² but often produces fibrocartilage and may deteriorate over time. Enhancements include bone marrow aspirate concentrate and thin wire drilling. Cartilage replacement is considered for larger, uncontained lesions or failures of marrow stimulation, with options like osteoperiosteal grafting, OATS plus BMAC, allografts, ACI/MACI, juvenile cartilage, and micronized cartilage. Arthroscopic techniques remain the goal, though optimal treatment continues to evolve with promising new methods under study.
