Race and Insurance Status Are Associated With Surgical Management of Isolated Meniscus Tears.

Purpose: The purpose of this study was to perform a population-level analysis to evaluate the effect of socioeconomic markers on the use of meniscus surgery in patients with meniscus tears.
Methods: We queried all hospital-based clinic visits from 2011 to 2014 in the Statewide Planning and Research Cooperative System database, which also contains all New York inpatient/outpatient visits. Patients with known prior knee surgery, meniscus tear before 2011, or other ligament injuries were excluded. The primary outcome was a meniscus procedure (meniscectomy or meniscus repair). Survival analysis was used to calculate the rate of meniscus surgery within 6 months. A multivariate model identified patient factors (age, sex, race, and payer) associated with surgical intervention.
Results: There were 32,012 patients identified who met the inclusion criteria. The rate of meniscus procedure within 6 months of diagnosis was 49.6%. Meniscectomy was performed in 98.8% of cases compared with 1.2% for meniscus repair. Rates of meniscus procedures were higher in patients who were older, male, and white, as well as those first diagnosed by a surgeon. The highest rates of meniscus procedures were in those with private, worker's compensation, or other insurance types. Multivariable analysis showed that female sex, non-white race, and public or self-pay insurance were independently associated with lower rates of meniscus surgery.
Conclusions: These results suggest both insurance-based and race-based disparities regarding surgical treatment. Additionally, the strongest variable for surgical management was a meniscus tear being first diagnosed by a surgeon.
Level of Evidence: Level of Evidence IV, retrospective case-control study.
