To the Editor In a recent article, Inacio et al1 analyzed data from 35 140 primary total hip arthroplasty cases from a total joint replacement registry (TJRR) to determine whether sex is associated with increased risk of revision. They concluded that women have a 29% higher risk of implant failure than men.1

The same analyses with the same statistical approach were repeated on a cohort of patients who underwent surgery in Italy and were registered in the Register of Orthopedic Prosthetic Implants (RIPO).2 The cohort consisted of 44 906 patients who underwent elective total joint replacement from 2000 through 2011. The median follow-up was 4.8 years. Women constituted 61% of the group, with a mean (SD) age of 69.2 (10.3) years. Men were younger, with a mean (SD) age of 66.8 (10.8) years, which is similar to the patients in the TJRR.
