Loosening of the femoral component after unicompartmental knee replacement.
نویسندگان
چکیده
We describe a technique for the diagnosis of loosening of the femoral component of the Oxford Unicompartmental Knee Replacement using accurately aligned lateral radiographs in extension and flexion. If gaps are present between the component and cement on one radiograph and not on the other, the component is loose.

متن کاملAssessment of radiolucent lines around the Oxford unicompartmental knee replacement: sensitivity and specificity for loosening.
The Oxford unicompartmental knee replacement gives good results in patients with symptomatic osteoarthritis of the medial compartment. Previous studies have suggested that the presence of radiolucent lines (RLLs) does not reflect a poor outcome in such patients. However, the reliability and validity of this assessment have not been determined. Our aim was to assess the intra- and interobserver ...

Background: Oxford medial unicompartmental knee replacement (UKR) is indicated in patients with anteromedialosteoarthritis (AMOA) of the knee. Microplasty (MP) instrumentation was introduced in 2012 as an improvement overphase 3 instrumentation. Advantages of this instrumentation include conservative tibial cut, decreased tibial re-cut rateand improved component alignment. We report the results...
