Case Study
The article presents a case study of a 14-year-old boy with osteosarcoma resection at the end of his right tibia who underwent reconstruction of the right leg with repiphysis expandable prosthesis. The patient's radiographs show effusion at the right knee and accumulation of debris in the prosthesis-bone interface. An open surgery reveals that the cobalt-chromium spring and ceramic internal component of the prosthesis were broken. After the surgery, he underwent outpatient physical therapy.
