Men have more complications after knee, hip replacements
Contrary to what had been previously believed, a study at the University of Toronto suggests that men, not women, have more complications from total joint replacement surgery.
For the study, a team of researchers analyzed Ontario hospital data between 2002 and 2009. The data included 38,000 total hip replacements (54 percent of which were for women), and about 60,000 total knee replacements (60 percent for women). The female total hip replacement patients were older than the male patients – 70 versus 65 years on average. There was no significant age difference for total knee replacements. Additionally, more of the female patients were classified as frail compared to male patients.
After analyzing postoperative data, the researchers found several gender differences following joint replacement surgery. Compared to women, men were 15 percent more likely to visit the emergency room in the month after the surgery. They were also more likely than women to have a heart attack in the three months following surgery (60 percent more likely after total hip, 70 percent after total knee), and men were 50 percent more likely to need corrective surgery in the two years following a total knee replacement.
Future studies aim to identify specific reasons for the gender differences.
