Post Market Clinical Follow-Up Study Protocol for PROFEMUR® Gladiator Cemented Femoral Stems

Study Overview
=================
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) European Union (EU) . These types of studies are required by regulatory authorities for all THA devices that do not have clinical evidence available at the time of gaining approval to market in the EU. This study has been designed in accordance with MEDDEV 2.12/2 rev 2.

Detailed Description
-----------------
Total hip arthroplasty (THA) has been performed since the early 1920s and is generally considered to be one of the most successful orthopaedic surgeries performed. The 8th Annual Report from the National Joint Registry of England and Wales reported 95.3% component survivorship at 7 years for over 300,000 THA implantations. MicroPort Orthopedics, Inc. (MPO) currently markets several THA components throughout the world, including the European Union (EU). As part of the process for gaining approval to market in the EU, MPO is conducting this post market clinical follow-up (PMCF) study to evaluate the safety and efficacy of these THA components. The objectives of this study are to evaluate component survivorship and total functional outcome scores of implanted subjects at out to 10 years follow-up.
