Social risk and patient-reported outcomes after total knee replacement: implications for Medicare policy.
The objective of this study was to determine if county- or patient-level social risk factors are associated with patient-reported outcomes after total knee replacement when added to the comprehensive joint replacement risk-adjustment model. Patient and outcomes data from the Function and Outcomes Research for Comparative Effectiveness in Total Joint Replacement cohort were merged with the CDC Social Vulnerability Index. The findings indicated that patient-reported race, education, and income were associated with patient-reported pain or functional scores; pain improvement was negatively associated with Black race and positively associated with higher annual incomes. The authors concluded that these findings suggested that patient-level social factors warrant further investigation to promote health equity in patient-reported outcomes after total knee replacement.

Living in immigrant communities does not impact total knee arthroplasty outcomes: experience from a high-volume center in the United States.
The objective of this study was to assess the relationship of neighborhood immigrant proportion (IP) to preoperative and 2-year postoperative pain and function after elective total knee arthroplasty (TKA) using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Patients in a high-volume institutional TKA registry were analyzed retrospectively, and demographics, pre-op and 2-year post-op WOMAC pain and function scores, and addresses obtained. Patient-level variables were linked to Census Bureau tract data. Researchers conclude that patients living in high IP neighborhoods do not have worse pre-op or 2-year post-op pain and function outcomes after TKA compared to those living in lower IP neighborhoods.

Disparities in TKA outcomes: census tract data show interactions between race and poverty.
Race is an important predictor of total knee arthroplasty (TKA) outcomes in the United States; however, analyses of race can be confounded by socioeconomic factors, which can result in difficulty determining the root cause of disparate outcomes after TKA. This study found that blacks and whites living in communities with little poverty have similar patient-reported TKA outcomes, whereas in communities with high levels of poverty, there are important racial disparities.
