Multicenter StudyRadiographic features of knee and hip osteoarthritis represent characteristics of an individual, in addition to severity of osteoarthritis.
To evaluate to what extent radiographic features of knees and hips that are normally related to osteoarthritis (OA) represent characteristics of an individual in addition to OA severity. ⋯ Using digital analyses of radiographic OA, strong correlations between joints within participants were found. These correlations diminished when OA became evident. This has implications for monitoring joint damage in (very) early OA with digital analyses.

Comparative StudyDifferences between questionnaire- and interview-based measures of activities of daily living (ADL) ability and their association with observed ADL ability in women with rheumatoid arthritis, knee osteoarthritis, and fibromyalgia.
Although self-report based on questionnaire is the common method to obtain information about activities of daily living (ADL) ability in rheumatic diseases, little is known about the relationship between measures of ADL ability based on questionnaire, interview, and observation. The present study examined whether measures of self-reported ADL ability based on questionnaire and interview yielded different results, determined whether the magnitude of the difference varied among women with rheumatoid arthritis (RA), knee osteoarthritis (OA), and fibromyalgia (FM), and investigated the relationships between self-reported and observed ADL ability. ⋯ Measures of self-reported ADL ability based on either questionnaire or interview have limited relationship to each other or to observed performance of ADL tasks.
