The purpose of this study is to investigate the effect of activity modification, exercises and a gradual return to sport in adolescents (age 10-14) with Osgood Schlatter disease. The primary outcome is self-reported recovery on a 7-point Likert scale at 3 months. Secondary endpoints include 4 and 8 weeks and 6 and 12 months after inclusion into the project. The adolescents will be recruited from primary schools, general practitioners and through online advertising on Facebook.
