Femoral head size and surgical approach affect dislocation and overall revision rates in total hip arthroplasty: up to 9-year follow-up data of 269,280 procedures in the Dutch Arthroplasty Register (LROI).

The anterior approach might reduce revision rates for both dislocation and all cause revision. Posterolateral approach is associated with a higher risk of dislocation revision but has a lower risk of any other revision. Increasing femoral head size up to 36 mm reduces revision for dislocation and improves overall revision rates for all approaches.
