Post Market, Retrospective Study to Evaluate Patients Implanted With Medacta Versafit Cup DM ™️ 2 Years Post-op

Study Overview
=================
Brief Summary
-----------------
This is a post-market, retrospective with one prospective visit, multi- center study, designed to assess the clinical outcomes, surgical details including Anterior or Posterior surgical approach, and collect all complication data of Medacta Versafit Cup DM used for primary or revision total hip arthroplasty at minimum two year post- operatively.
