Is this trial a fit for you?

Likely a good fit

Ideal candidates are individuals with symptomatic Hepple stage V talar osteochondral lesions who have not responded to conservative treatment.

Probably not a fit

Patients with lower limb deformities, joint diseases in the hip or knee, or other specified conditions may not benefit from this study.

What this trial studies

This clinical trial evaluates the effectiveness and safety of using autologous costal osteochondral transplantation to treat Hepple Stage V talar osteochondral lesions. Participants will be randomly assigned to receive either the experimental treatment or a control treatment involving autologous osteoperiosteal transplantation. The study aims to determine if the rib cartilage method leads to better clinical outcomes and less donor site morbidity compared to the control. All participants will follow the same rehabilitation and follow-up protocols post-surgery.

Why it matters

Potential benefit: If successful, this approach could improve recovery outcomes and reduce complications for patients with severe ankle cartilage damage.

How similar studies have gone: While similar approaches have been explored, this specific method of using rib cartilage for ankle lesions is relatively novel.
