AbstractThis study performed a health care utilization analysis between robotic arm assisted total knee arthroplasty (rTKA) and manual total knee arthroplasty (mTKA) techniques. Specifically, we compared (1) index costs and (2) discharge dispositions, as well as (3) 30-day (4) 60-day, and (5) 90-day (a) episode-of-care costs, (b) postoperative health care utilization, and (c) readmissions. The 100% Medicare Standard Analytical Files were used for rTKAs and mTKAs performed between January 1, 2016, and March 31, 2017. Based on strict inclusion–exclusion criteria and 1:5 propensity score matching, 519 rTKA and 2,595 mTKA patients were analyzed. Total episode payments, health care utilization, and readmissions, at 30-, 60-, and 90-day time points were compared using generalized linear model, binomial regression, log link, Mann–Whitney, and Pearson's chi-square tests. The rTKA versus mTKA cohort average total episode payment was US$17,768 versus US$19,899 (p < 0.0001) at 30 days, US$18,174 versus US$20,492 (p < 0.0001) at 60 days, and US$18,568 versus US$20,960 (p < 0.0001) at 90 days. At 30 days, 47% fewer rTKA patients utilized skilled nursing facility (SNF) services (13.5 vs. 25.4%; p < 0.0001) and had lower SNF costs at 30 days (US$6,416 vs. US$7,732; p = 0.0040), 60 days (US$6,678 vs. US$7,901, p = 0.0072), and 90 days (US$7,201 vs. US$7,947, p = 0.0230). rTKA patients also utilized fewer home health visits and costs at each time point (p < 0.05). Additionally, 31.3% fewer rTKA patients utilized emergency room services at 30 days postoperatively and had 90-day readmissions (5.20 vs. 7.75%; p = 0.0423). rTKA is associated with lower 30-, 60-, and 90-day postoperative costs and health care utilization. These results are of marked importance given the emphasis to contain and reduce health care costs and provide initial economic insights into rTKA with promising results.

Abstract Objective To assess whether patients with lupus have more complications and/or health care utilization than patients without lupus after primary total knee arthroplasty (TKA). Methods We used diagnostic codes to identify lupus (710.0) in patients who underwent primary TKA (procedure code, 81.54) in the US National Inpatient Sample from 1998–2014. We performed separate logistic regression analyses to assess whether lupus was associated with each in-hospital post-primary TKA complication (implant infection, implant revision, transfusion, mortality) or health care utilization for the index hospitalization. Results Our study cohort consisted of 8 127 282 primary TKAs with a mean age of 66.4 years, 63% were female, 68% White, 97% with OA, and the Deyo-Charlson comorbidity score was zero in 51%; 30 912 TKAs were performed in people with lupus. In multivariable-adjusted analyses, lupus was independently associated with a significantly higher risk of transfusion, but no significant difference in implant infection, implant revision or mortality, with respective odds ratios [ORs] (95% confidence interval [CI]) of 1.34 (1.25, 1.42), 1.38 (0.73, 2.60), 1.35 (0.83, 2.19) and 0.83 (0.34, 2.03). Lupus was independently associated with a significantly higher risk of total hospital charges above the median, the length of hospital stay >3 days (median) and discharge to an inpatient facility, respective ORs (95% CI) were 1.42 (1.22, 1.66), 1.09 (1.04, 1.15) and 1.34 (1.27, 1.41). Conclusion Our finding of higher transfusion rate and health care utilization in lupus compared with non-lupus patients undergoing primary TKA informs surgeons, patients and policy makers regarding TKA outcomes in lupus, and can also guide appropriate resource allocation.

AbstractMeasuring patient satisfaction and surgical outcomes following total joint arthroplasty remains controversial with most tools failing to account for both surgeon and patient satisfaction in regard to outcomes. The purpose of this study was to use “The Forgotten Joint Score” questionnaire to assess clinical outcomes comparing patients who underwent a total hip arthroplasty (THA) with those who underwent a total knee arthroplasty (TKA). We conducted a retrospective review of patients who underwent primary THA or TKA between September 2016 and September 2019 and responded to the Forgotten Joint Score-12 (FJS-12) questionnaire at least at one of three time periods (3, 12, and 21 months), postoperatively. An electronic patient rehabilitation application was used to administer the questionnaire. Collected variables included demographic data (age, gender, race, body mass index [BMI], and smoking status), length of stay (LOS), and FJS-12 scores. t-test and chi-square were used to determine significance. Linear regression was used to account for demographic differences. A p-value of less than 0.05 was considered statistically significant. Of the 2,359 patients included in this study, 1,469 underwent a THA and 890 underwent a TKA. Demographic differences were observed between the two groups with the TKA group being older, with higher BMI, higher American Society of Anesthesiologists scores, and longer LOS. Accounting for the differences in demographic data, THA patients consistently had higher scores at 3 months (53.72 vs. 24.96; p < 0.001), 12 months (66.00 vs. 43.57; p < 0.001), and 21 months (73.45 vs. 47.22; p < 0.001). FJS-12 scores for patients that underwent THA were significantly higher in comparison to TKA patients at 3, 12, and 21 months postoperatively. Increasing patient age led to a marginal increase in FJS-12 score in both cohorts. With higher FJS-12 scores, patients who underwent THA may experience a more positive evolution with their surgery postoperatively than those who had TKA.
