Hip Implant Failure Found to Be One-Third Higher in Women

February 28, 2013

Risk for revision surgery remained higher among women in the study after considering factors specific to the patient, surgeon, surgery, and type of implant.

Women who underwent total hip replacement were at an almost 30% increased risk for all-cause revision of the surgery compared with men who had undergone the same procedure (HR=1.29; 95% CI, 1.11-1.51). The risk, as reported online February 18 in JAMA Internal Medicine, remained even after adjustment for a multitude of risk factors, including those associated with the patient, surgeon, and surgery.

Risk for aseptic revision of the surgery was also increased in women vs men (HR=1.32; 95% CI, 1.10-1.58); however, there was no increased risk for septic revision between sexes.

The researchers looked at a prospective cohort of patients between 2001 and 2010 who underwent primary, unilateral hip replacement.

“The differences in prosthesis choices in men and women, as well as the follow-up of the presented study and non-measured possible confounders, are important considerations when interpreting these results,” the researchers wrote.
