Name of journal: JB & JS open accessAbstract: Advanced posttraumatic osteoarthritis (PTOA) of the knee is a cause of substantial disability, particularly in younger individuals, and the treatment of choice is total knee arthroplasty (TKA).

Advanced posttraumatic osteoarthritis (PTOA) of the knee is a cause of substantial disability, particularly in younger individuals, and the treatment of choice is total knee arthroplasty (TKA). Racial and socioeconomic disparities exist in the use of TKA, but, to our knowledge, there have been no studies examining these disparities among patients with PTOA.

Conclusions: Black and Hispanic patients are less likely than White patients to utilize TKA, and patients with private insurance are more likely to utilize TKA.
