Penn Study Exposes Stark Racial Gaps in Knee Replacement Surgeries

At the University of Pennsylvania’s annual Charles C. Leighton memorial lecture, Dr. Said Ibrahim laid bare persistent racial disparities in knee replacement surgeries that have gone unresolved for decades. His research shows that African American patients with severe osteoarthritis are significantly less likely to undergo these safe and effective surgeries compared to white patients, despite similar disease severity.

Ibrahim, now Dean of Thomas Jefferson University’s Medical College and a nationally recognized expert on healthcare disparities, highlighted that African Americans are 30 to 40 percent less likely to receive knee replacements. This gap persists even in the Veterans Affairs healthcare system, where insurance and cost barriers are removed. A VA study found that African American veterans were less likely to opt for surgery and more likely to anticipate worse outcomes like greater pain and longer recovery.

The problem is not just patient preference. Another study analyzed orthopedic surgeons’ recommendations and found minority patients were about 40 percent less likely to be advised to have surgery, even after adjusting for clinical factors. Surgeons often gauge patient readiness for the demanding recovery process, but cultural differences in communication can skew these assessments and reduce surgery recommendations for minority patients.

Ibrahim’s team tested an educational intervention funded by the NIH that improved surgery rates among African American patients by clarifying risks and benefits. This points to the need for systemic policy changes and culturally sensitive communication to close these gaps.

The findings underscore how racial disparities in healthcare access are not simply about patient choice or cost but are deeply embedded in provider interactions and systemic biases. As the U.S. population ages and osteoarthritis becomes more prevalent, ignoring these disparities condemns many minority patients to needless pain and disability. It is a stark reminder that equitable healthcare remains an unfulfilled promise in America.
