RESUMO
[Objective]To study the clinical results of treatment of local osteochondral fracture lesions on the talus dome associated with ankle fracture using autologous osteochondral transplantation.[Method]There were 18 patients with osteochondral fracture defects of the talus dome associated with ankle fracture, male 10, female 8, with the average age 33.5 years (18~49 years). Transplantation procedure was osteochondral cylinders from non-weight bearing surface of the ipsilateral knee and implant the donor graft into the recipient holes of talus cartilaginous defects with press-fit technique. The outcomes were assessed on the basis of ankle functional rating score, radiographic findings and MRI findings.[Result]The patients were followed up for 17 to 40 months (mean, 28 months). The ankle functional rating score was measured by the Baird and Jackson functional rating score system. The averaged scores was 96.3?3.5,excellent in 14 cases, good in 3 cases and fair in 1 case. The rate of being excellent and good was 94.4%.The rate of posttraumatic arthritis was 5.6% (1/18) and osteochondritis dissecans was 5.6% (1/18).[Conclusion]Autogenous osteochondral transplantation using ipsilateral knee osteochondral grafts is an effective surgical procedure on treating acute local osteochondral fracture lesions of the talus associated with ankle fracture.
