Willingness and access to joint replacement among African American patients with knee osteoarthritis: a randomized, controlled intervention

This report has been verified by one or more authors of the original publication.

663 African American patients with knee osteoarthritis (OA) were randomized into one of 4 groups, to assess whether educational interventions increased patient willingness to undergo total knee replacement (TKR). Patients were either allocated into a decision aid group, a motivational interviewing group, a combined decision aid and motivational interviewing group, or a control group. Following 12 months of assessments, results indicated that patients who received an educational intervention were significantly more willing to undergo TKR to treat knee OA, compared to the control group. However, there were no significant differences in willingness between the three intervention groups.
