Osteochondral lesions of the talus: computer-assisted retrograde drilling--feasibility and accuracy in initial experiences

Abstract

The authors developed a minimally invasive method with computer-assisted navigation for retrograde drilling of osteochondral lesions of the talus. Planning of the pathway and adjustment of the targeting device were performed outside the operating room. In 10 cadavers and four patients, accuracy of pin placement was in the range of 1.0-3.5 mm.
