Replacement hip operations reduce mortality

22 March 2013

Patients that undergo total hip replacement (THR) operations experience reduced mortality, heart failure risk, depression and diabetes, according to a new study.

Dr Scott Lovald, a researcher at Exponent, Inc and lead author on the paper, explained: "The study has demonstrated that THR confers a potential long-term benefit in terms of prolonged lifespan and reduced burden of disease."

The long term benefits of THR are relatively undocumented, but researchers are now beginning to investigate the impact of the procedure beyond the near-term.

Some 43,000 patients with osteoarthritis were divided into groups of those receiving THR and those not. All participants were then followed for at least a year, and nearly 24,000 for seven years.

The findings were adjusted for age, sex, race, region and Charlson score (the quantification number and severity of comorbidities).

THR patients were consistently observed to have a lower mortality risk - less than 52 per cent of the non-THR group. After the first year following surgery, heart failure risk was also reduced, as was diabetes.
