In Europe a femoral neck retaining stem (Metha, Aesculap Inc, Tuttlingen, Germany) has been reported with excellent midterm survivorship. We report on a US series and compare it to a review of reports in Europe over the past decade to determine if US experience matches that in Europe. A review of published studies was performed on PubMed with search terms: Hip, replacement, arthroplasty, and Metha. We found four publications that met the criteria of reporting survivorship and reasons for revision surgery. The results from these four articles combined had 4179 THA with the Metha stem. After IRB approval three orthopaedic groups in the US were used to combine their experience over the last 11 years. These US sources had 824 surgeries performed between 2008–2019. We then reported on all revisions for comparison of survivorship.Introduction
