Background: Autologous chondrocyte implantation (ACI) in the ankle was considered up to now an extremely technically demanding surgery with considerable morbidity for the patients. Hypothesis: Hyalograft C scaffold allows arthroscopic ACI, thanks to a specifically designed instrumentation. Study Design: Case series; Level of evidence, 4. Methods: Forty-six patients with a mean age of 31.4 years (range, 20-47) underwent operation from 2001 to 2004. They had posttraumatic talar dome lesions, type II or IIA. In the first step of surgery, an ankle arthroscopy was performed, with cartilage harvest from the detached osteochondral fragment or from the margins of the lesion. Chondrocytes were cultured on a Hyalograft C scaffold. In the second step of surgery, the Hyalograft C patch was arthroscopically implanted into the lesion, with a specifically designed instrumentation. Lesions
