Total knee arthroplasty for massive joint destruction in a patient with rheumatoid arthritis complicated with fibrous dysplasia

摘要

We report the case of a patient requiring total knee arthroplasty (TKA) due to massive knee bone deformities caused by rheumatoid arthritis (RA) complicated with polyostotic fibrous dysplasia. Reconstruction of the knee with large osseous defect was achieved with conventional TKA by impaction bone grafting. Benign tumor-like conditions such as fibrous dysplasia may be treated with conventional TKA instead of endoprosthesis, custom-made knee prosthesis, or osteoarticular allografting.
