Novel 3D printed partial talar surface prosthesis for osteochondral lesions of the talar dome: A 2-year case report

3D-printed PTSR is a new surgical method for OLTD with a larger damage area that can provide satisfactory outcomes. Definitive and convincing conclusions are difficult to draw owing to the limited number of cases in this study. Another limitation is the follow-up period, which was 2 years. In addition, medium- and long-term follow-up is required. For this patient, we planned an annual follow-up, which included physical evaluation and radiography. In the future, a prospective randomized controlled study should be conducted to manage the clinical surgical treatment of OLTDs, including metal partial replacements.
