Background: Knee arthroplasty has emerged as an effective treatment for end-stage gonarthrosis. Although total knee remains the gold standard, unicompartmental is appropriate alternative select patients. We sought to use a large, heterogeneous national database identify differences in thirty-day complication rates between and well risk factors complications. Methods: Patients ACS NSQIP (American College of Surgeons National Surgical Quality Improvement Program) who had undergone or from 2005 2011 were identified. CPT (Current Procedural Terminology) codes used cases elective primary arthroplasty. Statistical models employing univariate multivariate logistic regression identified associated with incidence morbidity mortality after Propensity score matching addressed demographic cohorts. Results: A 29,333 patients identified; 27,745 (94.6%) underwent 1588 (5.41%) Prior matching, cohort was 63.7% female mean BMI 32.8 ± 7.3 kg/m2, whereas values 55.3% 31.5 6.5 kg/m2 (p < 0.0001). The ages these cohorts 67.2 10.1 64.0 10.7 years, respectively previously developed implemented propensity algorithm address differences. Following rate did not differ significantly (5.29% compared 4.16%, p = 0.35), deep venous thrombosis (1.50% 0.50%, 0.02) duration hospital stay (3.4 2.2 days, 0.0001) higher cohort. Conclusions: Comparison revealed no overall short-term (thirty-day) mortality. this study does long-term subjective outcomes implant survival, findings should provide helpful information surgeons counseling considering and/or Level Evidence: Therapeutic III.
