Abstract

Objective: To develop and validate the Edinburgh Knee Function Scale (EKFS), to measure outcome in knee patients not requiring surgical management. Methods: Out-patients (551) with a non-surgical knee problem were recruited. Data collection was by postal questionnaire. The validation process followed the methods of Streiner and Norman. Results: The response rate was 78.2%. Cronbach's alpha was 0.87 and item-total coefficients ranged from 0.41 to 0.68. Test-retest reliability was adequate. Factor analysis identified three dimensions: symptoms and pain, basic functioning and impact on daily living. Face, content and construct validity were demonstrated. The scale correlated with the patients' ratings of the success of their treatment. Conclusion: We show EKFS to be a valid and reliable measure for measuring outcome in 'non-surgical' knee patients.
