The Differential Between Aseptic and Infection in Joint Replacement Patients

Seven years is kind of early for that. Shouldn't happen that early, but it sometimes does, rarely, but sometimes does. This could be pure purely mechanical or the adhesive is failing. It's not necessarily infection or some other inflammatory process going on. So that's what we call aseptic loosening. And then as you brought up infection, in this case, it's not the most common infection. But more likely a hematogenous seeding of the knee from an infection somewhere else in the body. That can happen at any time in the patient's lifetime.
