Preoperative Hip Injections Increase the Rate of Periprosthetic Infection After Total Hip Arthroplasty

摘要: Abstract Background Intraarticular injections are both diagnostic and therapeutic for patients with osteoarthritis. A potential risk of periprosthetic joint infection (PJI) after total hip arthroplasty (THA) may occur from direct inoculation and/or immune suppression by corticosteroids. Large population-level databases were used to evaluate injection on the 1-year rate PJI in undergoing primary THA. Methods State-level ambulatory surgery inpatient Florida California (2005-2012) identify THA preoperative postoperative windows possible or PJI, respectively. Patients grouped as no performed 6-12 months, 3-6 0-3 months injection. Risk adjustment was multivariable regression. Results 173,958 included; 5421 (3.1%) underwent an injection: 1395 (1.1%) 1863 2163 (1.2%) months. In month group, significantly increased at 3 (1.58%, P  = .015), 6 (1.76%, .022), 1 year (2.04%, .031) compared noninjection control group (1.04%, 1.21%, 1.47%, respectively). There differences 3- 6-month 6- 12-month groups. Conclusion is when within We recommend that their surgeons consider delaying elective until avoid this elevated infection.
