The purpose of this study is to provide clinical evidence for the safety and effectiveness of Ortho Development® Corporation's Entrada™ Hip System (Figure 1). The Entrada™ Hip System was fully introduced to the US market in July, 2018. The Entrada™ Hip System includes the Entrada™ Hip Stem, an FDA approved (510(K) # K171249) femoral stem coupled with either a cobalt chrome or Biolox® Delta Ceramic femoral head. Additionally, the stem and head are coupled with either the Escalade® or Legend® acetabular shell, both of which utilize highly cross-linked polyethylene liners.
