This study is a prospective, open-label, post-market, non-randomized, multi-center clinical evaluation of the Secur-Fit Advanced Hip Stem for primary total hip arthroplasty with a cementless application in a consecutive series of patients who meet the eligibility criteria. The success rate of the Secur-Fit Advanced femoral stem, defined as absence of stem revision for aseptic loosening or femoral fracture, is expected to be no worse than 99% at 5 years postoperative with a non-inferiority margin of 2.5%.
