The Knee Injury Osteoarthritis Outcome Score (KOOS) is a widely used joint-specific measure employed to evaluate pain, symptoms, activities of daily living, recreational activities, and quality of life in patients with knee osteoarthritis (OA). Although the original KOOS has been translated into many languages, a Saudi Arabic version is not available. This study aimed to culturally adapt and evaluate the psychometric properties of the Saudi Arabic version of the KOOS in patients with knee OA. ⋯ Excellent internal consistency (Cronbach's alpha = 0.87-0.92) was detected in the subscales of the adapted version, as well as excellent test-retest reliability (ICC2,1 = 0.92-0.94). The pattern of correlation between the subscales of the Saudi Arabic version of the KOOS, SF-36 domains and the Visual Analog Scale for pain supported the construct validity of the adapted version. The Saudi Arabic version of the KOOS was well accepted and exhibited excellent reliability, internal consistency, and construct validity in Saudi patients with knee OA.

In the process of the planned and systematic education of patients/families, it is extremely important to identify patients' health problems as well as their needs and expectations. The objective of this study was to determine the relationship between functional disability, health problems and perceived educational needs in people with systemic sclerosis (SSc). This was a cross-sectional analytic study conducted in six rheumatology centers in Poland. ⋯ All health problems had significant correlations with the overall educational needs, pain, functional disability and fatigue having the highest rs = 0.359, p < 0.0001; rs = 0.314, p < 0.001 and rs = 0.270, p = 0.001, respectively. Health problems in people with SSc are associated with considerable educational needs; therefore, health professionals should take this into account when planning patient education. Group interventions should consider providing patient education related to disease process as a minimum.
