Due to the severity of the lesion, a resurfacing procedure was chosen. Based on CT data, a bi\u2010layered resurfacing implant consisting of a titanium socket and a polycarbonate urethane bearing surface was constructed. For intraoperative guidance, a set of matching drill guides were 3D\u2010printed, along with some models of the affected talus, to allow for dry\u2010lab training. Surgical implantation using a medial malleolar osteotomy to approach the lesion was without complications. Orthopedic follow\u2010up examinations were conducted at 10\u2009days, 4\u2009weeks, 6\u2009weeks, 6\u2009months and 12\u2009months.

ROM differed by 15\u00b0 in flexion compared to the contralateral side, while there was no difference in extension. Moderate periarticular fibrosis was present at 12\u2009months.
