Brief summary
MicroPort Orthopedics (MPO) is conducting this post market clinical follow-up (PMCF) study to evaluate the safety and efficacy of its total hip arthroplasty (THA) and resurfacing components marketed in the European Union (EU). These types of studies are required by regulatory authorities for all THA and resurfacing devices that do not have medium to long-term clinical evidence available at the time of gaining approval to market in the EU. This study has been designed in accordance with the medial device directives (MEDDEV) 2.12/2 rev 2.
