Elective hip or knee replacement is an optimal, standardised orthopaedic surgical procedure. The influence of chronic kidney disease, defined as an estimated glomerular filtration rate (eGFR) of 15-45 ml/min/1.73 m
We conducted a retrospective multicentre analysis involving two orthopaedic centres. Patients who underwent elective total hip and knee replacement between 2010 and 2015 were included. We used descriptive methods and multivariate linear and binary regression analyses for our statistical evaluations.
We evaluated 3301 datasets (1120 men [33.9%], 2181 women [66.1%], 2043 [61.9%], and 1258 [38.1%]) elective total hip and knee replacements, respectively. The following variables were identified as risk factors for a prolonged hospital stay: patient age, admission Hb and potassium levels, perioperative Hb level decrease, year of surgery, blood transfusion, and a preoperative eGFR of 15-45 ml/min/m
