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.
在单髁膝关节置换术周围的X线片上经常会出现透亮线。目前尚不清楚为何会出现这种情况，尽管这些线通常在手术后的第一年出现。膝关节置换植入物在第一年也会发生移位。考虑到透亮线出现的时间与植入物移位的时间相似，似乎它们之间可能存在关联。本研究的目的是确定透亮线的存在与牛津单髁膝关节置换植入物的移位之间是否存在相关性。
