Usability testing of an individualized decision aid for total knee arthroplasty.

ABSTRACT:

Objectives

Osteoarthritis (OA) is a leading cause of total knee arthroplasty (TKA), affecting over 15 % of Canadians. With an aging population and suboptimal use of non-surgical options, TKA rates and wait times are rising. Although TKA is effective, 30 % of patients are dissatisfied due to unmet expectations, suggesting some surgeries may be inappropriate. Patient decision aids can set realistic expectations, improve decision quality, and enhance satisfaction. We developed an individualized online patient decision aid allowing patients to compare treatment outcomes based on similar characteristics (age, sex and body mass index) and evaluated its usability before clinical implementation.

Methods

Participants were recruited from a high-volume urban hip and knee clinic.
