Charcot joint disease is a rare neurogenic lesion of the characterized by progressive destruction with dislocation or subluxation. However, whether replacement should be performed for severe damage controversial.This paper reports case large bone defect that was treated arthroplasty assisted customized 3D-printed porous tantalum. The patient admitted to hospital 9-year history bilateral knee pain had aggravated in past 2 months. Radiography showed osteogeny and sclerosis both knees, free fragments, heterotopic ossification, new bone, osteophyte formation, irregular margins, apparent narrowing space, (Anderson Orthopedic Research Institute classification type III). Based on present illness, history, imaging, laboratory examination, confirmed. Conservative treatment has been reported literature. There are limited surgical disease. We followed up year after operation, imaging clinical evaluation results were good. Postoperative X-ray examinations good alignment force lines, no evidence loosening. mobile did not need crutches.Through accurate preparation tantalum implants, AORI III can effectively restore range motion joint, lower limb alignment, finally achieve functional walking without crutches.
