One Year Later: The Lasting Effect of the COVID-19 Pandemic on Elective Hip and Knee Arthroplasty.

BACKGROUND

The severe acute respiratory syndrome coronavirus 2 (COVID-19) pandemic has continued to generate notable disruption in elective total hip arthroplasty (THA) and total knee arthroplasty (TKA). The purpose of this study was to determine whether there is any difference in patient characteristics, revenue, and clinical outcomes in patients undergoing THA and TKA after the start of the pandemic.

METHODS

We reviewed a consecutive series of 26,493 patients undergoing primary and revision THA and TKA by 48 surgeons in a single arthroplasty practice. We compared demographics, comorbidities, outcomes, and surgeon revenue from THA and TKA procedures from March 2020 to February 2021 with a prepandemic group undergoing a procedure from March 2019 to February 2020.

RESULTS

There was a 20% decline in the volume of all cases in the pandemic group ( 11,688 versus 14,664 , P < 0.001). The postpandemic cohort had shorter length of stay (1.58 versus 1.70 days, P = 0.007), had higher rates of home discharge (98% versus 91%, P < 0.001), and were more likely to have their procedure done at an outpatient facility (21% versus 7%, P < 0.001). Even among patients older than 65 years, more pandemic patients underwent a procedure as an outpatient (19% versus 7%, P < 0.001), with no difference in complications or readmissions. Total surgeon charges and payments declined by 17.6% and 16.3%, respectively, during the pandemic ( P = 0.010).

CONCLUSION

Although the COVID-19 pandemic resulted in a notable reduction in surgical volume and revenue loss for our practice, we found a marked shift of arthroplasty patients to outpatient facilities with increased rates of home discharge without compromising patient safety.
