A Comparison of the Incidence of Complications Following Total Hip Arthroplasty in Patients With or Without Osteonecrosis

Osteonecrosis (ON) is a common cause of hip arthritis requiring arthroplasty (THA). ON patients often have associated conditions that place them at a greater risk for complications. The aim of this study is to determine complication rates of ON versus other THA patients. Statewide hospital admissions for THA were identified (1995–2010). THA procedures and ON diagnosis were identified using ICD-9 codes. Logistic regression analysis was used to determine the role of ON as a predictor of complications. ON led to an increased risk of sepsis and readmission. There was no significant difference in mortality rate. This study demonstrates that patients with ON undergoing THA have increased rates of readmission and sepsis. These findings are helpful in allocating resources for treating this patient group.
