Intra-articular injection prior to THA linked with infection, early revision
March 11, 2014
NEW ORLEANS — In a retrospective study using databases for Ontario, Canada, researchers found intra-articular injection 1 year before elective, primary total hip arthroplasty for osteoarthritis was associated with early revision precipitated by infection.
“We found that most arthroplasty patients who had a prior [intra-articular] injection had it a year before their surgery and that this injection was a risk factor for early revision mediated by infection,” Bheeshma Ravi, MD, said during his presentation at the American Academy of Orthopaedic Surgeons Annual Meeting, here.
The reseachers identified 37,881 patients who underwent primary total hip arthroplasty (THA) between 2002 and 2009 for osteoarthritis. Of these patients, 2,468 had at least one intra-articular injection by a radiologist 5 years before their surgery and nearly 70% of this group received the injection 1 year prior to THA.
