Abstract: In our case, 3D printing was used to fabricate a custom-made titanium alloy total talar prosthesis as  a mirror image of the contralateral healthy talus for a 16-year-old girl who underwent right talar resection for a  recurrent giant cell tumour (GCT) of the talus. A porous surface was used over the neck and tail of the talus  prosthesis to promote soft tissue attachment and improve the stability of the prosthesis. Pre-drilled medial and  lateral holes were prepared for ligament repair and attachment. Eighteen months after the operation, there was  no tumour recurrence, and the patient walked without symptoms. The Musculoskeletal Tumour Society score was  22/30, the American Orthopaedic Foot and Ankle Society score was 88/100, and the prosthesis was well positioned  on radiographs. The short- and medium-term outcomes indicated that 3D-printed modular talar prostheses could  be an effective treatment option.
