Trends in utilization of meniscal allograft transplantation between 2010 and 2019.

Abstract

The aim of this study was to observe the trends in (1) utilization of meniscus allograft transplantation (MAT), (2) demographics and comorbidities of patients undergoing transplants and (3) reimbursements for this procedure between the years of 2010 and 2019. Using a national database, patients who underwent MAT were observed. Incidence of MAT, percentage of female patients, average age, and average Charlson comorbidity index (CCI) were analyzed between 2010 and 2019. Average reimbursement during the index and postoperative 90-day bundle period were also calculated from 2010 to 2019. Compound annual growth rate (CAGR) of change in incidence, demographic and reimbursement was calculated, and linear regressionwas conducted for each trends analysis. In total, 744 patients underwent a MAT between the years of 2010 and 2019. The incidence of MAT increased from 0.12 per 100,000 to 0.15 per 100,000 during this period but was not statistically significant (p=0.345). There was no significant difference in age (p=0.462) and gender (p=0.831) among the patients, but the average CCI significantly increased from 2010 to 2019 (CAGR: +15.30; p=0.001). The total reimbursement in the index (p=0.451) and 90-day bundle period (p=0.191) did not significantly change from 2010 to 2019. Although MAT has been shown to be a safe and reliable surgery for the treatment of meniscus deficient knees, the incidence of MAT as well as the population undergoing MAT has minimally increased from 2010 to 2019. Future studies should seek to identify why the utilization of this efficacious surgery has not increased. IV; Descriptive Epidemiology Study.
