Dawson et al developed a 12-item questionnaire for evaluating a patient before and after total knee replacement. This is a simple instrument that is easy for patients to complete yet provides important insights to the effectiveness of the surgery. The authors are from the University of Oxford, Nuffield Orthopaedic Centre and Radcliffe Infirmary in Oxford, England.
Interval covered: past 4 weeks

total score =
= SUM(points for all 12 items)
Interpretation:
• minimum score: 12
• maximum score: 60
• The higher the score the more severe the functional status of the knee.
percent normal function =
= (60 - (total score)) / 48 * 100%
Purpose: To evaluate the knee of a patient before or after a total knee replacement using the 12-item questionnaire of Dawson et al (Oxford knee status).
