Key Points

To evaluate the feasibility, oncologic control, and functional outcomes of total navicular replacement using a custom 3D-printed titanium implant for a rare midfoot giant cell tumor.
Designed a patient-specific porous titanium implant via virtual surgical planning with fixed screw trajectories for talocuneiform fusion.
Performed en bloc excision and custom implant placement via a medial approach in a 32-year-old male with a Campanacci grade II navicular giant cell tumor.
Assessed pain, gait, functional scores, and radiographic osseointegration across a 2-year postoperative follow-up period.
The patient achieved complete pain resolution, a normal gait, and excellent functional scores by 2 years post-surgery.
Radiographic imaging at 2 years confirmed successful osseointegration of the titanium implant with no tumor recurrence.
