Synopsis
49 patients scheduled for hip resurfacing were randomized to either an anterolateral approach or posterior approach. Patients were assessed for component migration on radiostereometric analysis over 2-year follow-up, as well as periprosthetic bone mineral density, clinical results, and incidence of radiolucency and osteolysis. Total translation and rotation of the acetabular component was signific...
