Background Injection of the hip is performed for diagnostic and therapeutic reasons. Articular cartilage deterioration and increased risk of prosthetic infection have been reported with steroid injections. However, the literature contains contradictory reports on an increased risk of infection after a subsequent THA.
Questions/PurposesWe asked whether intraarticular steroid injection increased the rate of infection of a subsequent THA. Methods We retrospectively reviewed records of 175 patients in whom intraarticular steroid injections were given under strictly aseptic conditions using a lateral approach within 1 year before THA. These patients were matched with others from our database who had not received an injection for comorbidities, and for American Society of Anesthesiologists score, age, BMI, sex, type of implant, and year of THA.
