Objective: Compare baseline characteristics and change in outcomes in patients with symptomatic knee or hip OA participating in patient education and exercise therapy. Design: Longitudinal cohort study. Good Life with osteoArthritis in Denmark (GLA:D®) is an 8-week patient education and supervised exercise program delivered by certified clinicians. Changes in pain intensity, Knee injury/Hip disability Osteoarthritis Outcome Scores’ subscale Quality of Life (K/HOOS QOL), EuroQoL 5-Dimensions 5-Level (EQ-5D) and 40 m walk test at ∼3 and 12 months were compared between knee and hip patients. Results: 24,241 knee and 8,358 hip patients were included, with response rates of 75% and 60% at ∼3 and 12 months. Age, gender, symptom duration, pain medication use, pain intensity, physical function and quality of life were alike. More knee than hip patients were obese and had bilateral symptoms. At 3 months, clinically relevant improvements were seen in both knee and hip OA patients with clinically irrelevant between groups differences; 2.1 (1.5; 2.8) mm in pain intensity, −1.1 (−1.5; −0.7) point in K/HOOS QOL score, −0.010 (−0.013; −0.007) in EQ-5D index score and −0.02 (−0.02; −0.01) m/sec in walking speed. At 12 months the slight immediate differences were equalized. Conclusion: Patients presenting with knee and hip OA in primary care were on average more alike than different. Following treatment, clinically relevant improvements were seen in both knee and hip OA patients at 3 and 12 months. Patients with knee and hip OA should be prioritized alike for treatment with patient education and supervised exercise therapy.
