Which outcome measures are considered best for evaluating outcomes after total shoulder arthroplasty?

• A. WOOS and ASES
• B. DASH and SPADI
• C. PENN and SST
• D. OSPRO-YF

Answer: (A)

Focus on using validated, shoulder-specific patient-reported outcome measures that capture both pain and function as well as overall quality of life after total shoulder arthroplasty. WOOS offers a disease-specific quality-of-life perspective tailored to shoulder conditions, including arthroplasty, and is sensitive to changes in how the shoulder affects daily life. ASES provides a widely used, reliable 100-point composite of pain and function, giving a clear and comparable measure across studies and patients. Using these two together gives a robust picture: ASES delivers a concise snapshot of pain and functional ability, while WOOS adds depth on how the shoulder condition impacts broader aspects of the patient’s life.

DASH and SPADI are valid shoulder-related tools but are not as specifically tuned to arthroplasty outcomes in this context. PENN and SST focus more on satisfaction and patient-specific function, and OSPRO-YF is a psychosocial screening questionnaire rather than an outcome measure for shoulder function.
