Conclusion

The present meta-analysis intended to summarize the best evidence available to date. According to these results, the dislocation rate after THA is not different between PA and DAA. Furthermore, we did not find notable differences in the rate of dislocation associated with cup positioning in the safe zone through either approach, and when surgical factors related with prosthetic hip instability were assessed and compared for each approach. It can be concluded that the selection of surgical approach has little influence in the development of this complication.
