What is the primary patient-reported outcome measure for osteoarthritis (OA) and total knee arthroplasty (TKA)?

• A. KOOS
• B. Lysholm knee score
• C. WOMAC
• D. Lower extremity functional scale

Answer: (C)

The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) is recognized as the primary patient-reported outcome measure for osteoarthritis, particularly in relation to total knee arthroplasty (TKA). WOMAC is specifically designed to assess pain, stiffness, and functional limitations in patients suffering from osteoarthritis of the hip and knee. Its focus on these key areas makes it particularly relevant for evaluating outcomes in TKA patients, as the procedure aims to reduce pain and improve function. The WOMAC is widely used in clinical trials and practice because of its reliability and validity in capturing the experiences of patients undergoing knee treatments. It allows clinicians to understand how osteoarthritis affects a patient's daily activities and overall quality of life, which is critical for assessing the effectiveness of treatments like TKA. In contrast, while other measures like the KOOS, Lysholm knee score, and Lower Extremity Functional Scale also assess knee function and symptoms, they are either broader in scope or focused on specific aspects of knee conditions rather than being explicitly tailored for osteoarthritis and total knee arthroplasty. This specialized focus is why WOMAC stands out as the primary measure in this context.
