NCT06527482

Brief Summary

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

Outcome Measures

Primary Outcomes (1)

  • Foot and Ankle Outcome Score (FAOS)

    The Foot and Ankle Outcome Score (FAOS) is an extensive tool designed to evaluate the patient's perception of their foot and ankle conditions, with 0 indicating the worst possible outcome, and 100 representing the best possible outcome. The scale of FAOS score will be answered by participants during clinic follow-up preoperatively, and 6 weeks 3, 6, 12 and 24 months after surgery.

    Pre-surgery and 6 weeks and 3, 6, 12 and 24 months after surgery

Secondary Outcomes (6)

  • American Orthopedic Foot and Ankle Society Score (AOFAS)

    Pre-surgery and 6 weeks and 3, 6, 12 and 24 months after surgery

  • Visual Analogue Scale (VAS)

    Pre-surgery and 6 weeks and 3, 6, 12 and 24 months after surgery

  • Ankle Activity Score (AAS)

    Pre-surgery and 6 weeks and 3, 6, 12 and 24 months after surgery

  • Magnetic Resonance Observation of Cartilage Repair Tissue (MOCART)

    12 and 24 months after surgery

  • International Cartilage Repair Society (ICRS)

    12 months after surgery

  • +1 more secondary outcomes

Interventions

After full exposure of the lesion, the center of the cystic lesion was determined and drilled perpendicularly using a 2-mm pin. Then, a 4.5-mm cannulated bore was used to drill the lesion until the cyst was reached, and a small bone socket was created. A harvester tube matching the diameter of the cyst was used to enlarge the bone socket with care to avoid damage to the adjacent normal cartilage. The cystic lesion was debrided thoroughly, and the sclerotic wall of the cyst was freshened using a curette. The harvester tube with a matched diameter was driven in to a depth of 15 to 20 mm at the 2-cm proximal part of the anterior superior iliac spine perpendicularly without violation of the lateral wall of the crest. When necessary, small pieces of cancellous bone were also harvested from the iliac crest using a bone curette then grafted into the peripheral area of the cyst to fill up the remaining space of the cyst around the bone socket in the talus.
