SAN DIEGO — Patients who received multiple intra-articular steroid hip injections prior to total hip arthroplasty experienced a high risk of future periprosthetic joint infections, according to results presented at the American Academy of Orthopaedic Surgeons Annual Meeting.
“If [a patient has] multiple injections leading up to the surgery, it does significantly increase the chance of the patient having an infection after hip replacement,” Young-Min Kwon, MD, PhD, of Massachusetts General Hospital and Harvard Medical School, told Healio.com/Orthopedics.
Kwon and colleagues matched 100 patients who received two or more intra-articular steroid hip injections prior to total hip arthroplasty (THA) with 350 patients who received one intra-articular steroid hip injection prior to THA based on age, sex, American Society of Anesthesiologists preoperative score, presence of diabetes as a comorbidity and BMI.
Results showed an infection rate of 2% and 6% in the single and multiple injection groups, respectively. Researchers noted seven infections in both the single-injection and multiple-injection groups.
“Now, we have data which the orthopedic surgeon can use to counsel the patient about the risk that is associated with having more than one [steroid] injection,” Kwon said. – by Casey Tingle
