A recently presented study identified age, gender and racial minority status
as risk factors for perioperative surgical site infection following total hip
and knee arthroplasty.
"Our regression model revealed that patient-related factors such as age

…Compared to a referent group of patients aged 45 years to 64 years,
patients aged 44 years or younger had 1.7 times higher odds of having an SSI.
Compared to the referent group, patients aged 65 years to 74 years had a 0.9
times higher odds, and those 75 years or older had a 0.98 times higher odds.
The investigators also found that men had a 1.33 times higher odds for SSIs
