In the multivariate analysis, RPE remained a relevant independent factor (P=0.035) for future UKA. An ROC analysis found that the cut-off point of RPE was 33% (sensitivity, 81.2%; specificity, 63.3%). RPE was a predictor of the prognosis of patients who underwent UKA within 1year after the onset of SONK. Our results suggest that patients with RPE≥33% are at high risk for progression. RPE was a predictor of the prognosis of patients who underwent UKA within 1 year after the onset of SONK. Our results suggest that patients with RPE ≥ 33% are at high risk for progression. As the prevalence of peripheral vascular disease (PVD) continues to increase nationwide, studies demonstrating its effects following primary total knee arthroplasty (TKA) are limited. Therefore, the purpose of this study was to evaluate whether patients with PVD have higher rates of 1) in-hospital lengths of stay (LOS); 2) readmissions; 3) medical complications; 4) implant-related complications; and 5) costs of care. Using a nationwide database, patients with PVD undergoing primary TKA were identified and matched to controls in a 15 ratio by age, sex, and medical comorbidities. The query yielded 1,547,092 between the cohorts. Outcomes analyzed included in-hospital LOS, readmission rates, complications, and costs of care. A p-value less than 0.004 was considered statistically significant. PVD patients had significantly longer in-hospital LOS (4-days vs. 3-days, p<0.0001). Additionally, the study cohort had a higher incidence and odds (OR) of readmissions (20.5 vs. 15.2%; OR 1.43, 95% CI 1.42-1.45, p<0.0001), medical complications (2.46 vs. 1.32%; OR 1.88, CI 1.83-1.94, p<0.0001), and implant-related complications (3.82 vs. 2.18%; OR 1.78, CI 1.26-1.58, p<0.0001). Additionally, the study found patients with PVD had higher day of surgery (p<0.0
