Construct validity was assessed by evaluating the correlation between the single-joint outcome measures and validated function questionnaires using Spearman\u2019s rank correlation. Responsiveness or sensitivity to change was assessed through calculating effect size and standardized response means (SRM). Reliability of physical examination measures was assessed by determining interobserver agreement.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results.<\/jats:title><jats:p>The single-joint PRO were highly correlated with each other and correlated well with validated functional measures.
