Best Practice Case Studies-American Orthopaedic Foot and Ankle Society

Pdf Summary

The American Orthopaedic Foot & Ankle Society (AOFAS) supports the use of osteochondral autograft and allograft transplantation for treating osteochondral lesions of the talus (OLT). These procedures are particularly recommended for large diameter lesions, cystic lesions, and cases where previous surgical interventions have failed, and are not considered experimental for patients who have not benefited from nonoperative management.<br /><br />Osteochondral lesions of the talus involve damage or degeneration of the talus bone and its overlying cartilage, leading to significant pain and potential disability. While smaller lesions often respond to marrow stimulation techniques like microfracture, this treatment sometimes results in inferior fibrocartilage compared to the native Type II collagen cartilage. In contrast, osteochondral transplantation replaces damaged areas with bone and cartilage plugs, showing better results for larger or cystic dictions and failed prior surgeries.<br /><br />Research supports osteochondral transplantation's effectiveness, with studies reporting high success rates, significant improvements in pain and clinical scores, and a high percentage of athletes returning to sports. Long-term follow-up studies highlight ongoing positive outcomes, further establishing this treatment as viable and effective.<br /><br />Autografts, which use a patient’s tissue, show promising results, although they may cause donor site morbidity in some patients. Allografts sourced from cadavers are beneficial for cases with very large lesions or unsuitable autograft sites. Both autograft and allograft techniques have distinct roles in managing persistent and debilitating OLT cases.<br /><br />Overall, osteochondral transplantation is promoted as a substantial advancement in care for OLT, reducing pain and dysfunction, with continued effectiveness over the long term, as substantiated by numerous peer-reviewed studies.
