The goal of this clinical trial is to establish a multicenter prospective cohort of patients with severe osteochondral lesion of the talus (OLT), evaluate the clinical efficacy of autologous osteoperiosteal transplantation and the incidence of postoperative donor-site morbidity. The main questions it aims to answer are: Does autologous osteoperiosteal transplantation have good clinical outcomes in the treatment of severe OLT? Does autologous osteoperiosteal transplantation treat severe OLT with fewer postoperative complications? Participants will: Undergo autologous osteoperiosteal transplantation for OLT Receive clinical follow-up 3, 6, 12, and 24 months after surgery and answer scales of ankle function assessment Take CT and MRI preoperatively and 12 and 24 months after surgery
