Background and purpose - Acute kidney injury (AKI) is associated with increased short-term and long-term mortality in intensive care populations and in several surgical specialties, but there are very few data concerning orthopedic populations. We have studied the incidence of AKI and the prevalence of chronic kidney disease (CKD) in an elective population of orthopedic patients undergoing primary total hip replacement, hypothesizing that chronic kidney disease predisposes to AKI. Patients and methods - This was a single-center, population-based, retrospective, registry-based cohort study involving all primary elective total hip replacements performed from January 2003 through December 2012. Patient demographics and creatinine values were registered. We evaluated the presence of CKD and AKI according to the international guidelines for kidney disease (KDIGO Acute Kidney Injury Workgroup 2013 ). Results - 3,416 patients were included (2,064 females (60%)). AKI (according to KDIGO criteria) was seen in 75 patients (2.2%, 95% CI: 1.7-2.7) in the course of primary total hip replacement. Of these, 26 had pre-existing CKD of class 3-5. Pre-existing CKD of class 3-5, indicating moderately to severely reduced kidney function, was seen in 374 individuals (11%). Interpretation - Development of acute kidney injury appears to be a substantial problem compared to other complications related to elective total hip arthroplasty, i.e. luxation and infection. Patients with pre-existing chronic kidney disease may be especially vulnerable. The clinical impact of acute kidney injury in an elective orthopedic population remains to be elucidated.
