s163 retrospectively reviewed patients who underwent a primary TKA for osteoarthritis from the Premier Perspective Database between 2014 and 2016. Patients with a bicruciate knee system were identified using "journey"-related appropriate keywords from billing records and compared against other TKA patients who did not meet the keywords' criteria. Patients were excluded if they were < 21 years of age; outpatient hospital discharges; evidence of revision TKA; bilateral TKA in same discharge or different discharges. 1:1 Propensity Score Matching was used to control patients, hospital (except hospital bed-size) and clinical characteristics. Generalized Estimating Equation (GEE) model accounted for hospital bed-size with appropriate distribution and link function. Cost data were inflation-adjusted for 2016 U.S. dollar and rounded to the nearest dollar. Results: The study matched 1,692 bicruciate knee system patients with other TKA patients. Length of stay for bicruciate knee patients (mean= 2.45 days; CI= 2.38-2.52) were significantly lower than other TKA patients (mean= 2.66 days; CI= 2.59-2.74). Bicruciate knee patients were 35% (OR= 1.35; CI= 1.13-1.61; p value= < .0001) more likely to be discharged to home/home health care and 41% (OR= 0.59; CI= 0.48-0.74; p value= < .0001) less likely to be discharged to a Skilled Nursing Facility than other TKA patients. Mean total hospital costs were significantly lower for bicruciate knee patients
