Example of radiographic ongrowth score for endoprostheses (ROSE) using the extra-osteal non-porous collar: a radiograph immediately post-implantation showing the osteotomized bone abutting the collar without radiolucencies, and b radiograph after 24 months demonstrating radiolucencies anteriorly and posteriorly between the host bone and non-porous collar, indicating a ROSE score of -2 on this radiograph
