RADIOGRAPHS WERE PROVIDED WITH (B)(4): CONSISTING OF AP AND LATERAL VIEWS OF THE LEFT KNEE AND A 3-D SURFACE RECONSTRUCTION FROM CT OF THE LEFT KNEE. MMI REVIEW IDENTIFIED EXTENSIVE DISTAL FEMORAL OSTEOLYSIS AND A FRACTURE OF THE LATERAL FEMORAL CONDYLE WHICH SUPPORTED THE REPORTED EVENT. THE IMPLANT FIT APPEARED TO BE MAINTAINED DESPITE THE DISTAL FEMORAL OSTEOLYSIS. REGARDING ALIGNMENT, THE TIBIAL IMPLANT WAS LATERALLY POSITIONED IN RELATION TO THE FEMORAL IMPLANT AND KNEE VALGUS WAS EVIDENT. NO DEFINITE LOOSENING OF THE IMPLANTS COULD BE SEEN DESPITE THE EXTENSIVE RADIOLUCENCY SECONDARY TO OSTEOLYSIS.
