Radiolucent lines frequently appear on radiographs around unicompartmental knee arthroplasties. It is unknown why this occurs, although the lines usually appear during the first year following the procedure. Knee arthroplasty implants are also known to migrate during the first year. Considering the similarity in the timing of appearance of radiolucency and implant migration, it seems that they could be related. The aim of this study was to determine whether there is a correlation between presence of radiolucency and the migration of Oxford unicompartmental knee arthroplasty implants.
