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.
