This study will compare the effects of a novel web-based program (Joint Academy) to regular face-to-face treatment (the BOA program) for people with osteoarthritis of the knee. Half of the participants will be randomized to the web-based program whilst the other half will receive regular face-to-face care.

According to national and international guidelines, osteoarthritis (OA) treatment consists of exercise and information. The face-to-face BOA program is a model to deliver this treatment at primary care facilities in Sweden. Presently less than 20% of people with OA receive adequate treatment. This may be due to lack of healthcare resources or people having trouble to fit their schedule to primary care opening hours. To facilitate a better OA care, alternative methods are therefore required.

A two-armed randomized clinical superiority trial will be performed to compare OA treatment by a web-based program, Joint Academy, with the traditional face-to-face BOA program in 270 adults with clinically verified OA. Using intention-to-treat analysis and per-protocol, evaluations will be performed at baseline, after 6 weeks and after 3, 6 and 12 months. The primary outcome is physical function. Secondary outcomes are joint pain, health-related quality of life, self-reported function, amount of time of physical activity/exercise and overall satisfaction. A health-economic analysis will also be performed. The primary endpoint will be at 12 months. Data will be monitored using web-based questionnaires in Joint Academy, and regular paper questionnaires for the face-to-face treatment.

Should the trial show superiority in favor of Joint Academy, an implementation of the web-based treatment would benefit both patient and society at large, since Joint Academy entails a more flexible treatment in regards to time and location, and is not as costly per-patient as regular face-to-face treatment.
