Severe knee pain, lower- limb strength deficits, and reduced knee function are cardinal findings in OSD. Despite severe knee pain, adolescents with OSD continue with frequent and intense sports participation. This highlights the need for interventions which address functional deficits, while helping adolescents manage their sports load. Purpose / Aim of Study: The aim of this study was to investigate the effect of load management with progressive knee strengthening in adolescents with OSD. Materials and Methods: This pre-registered (NCT02799394) prospective cohort study included 51 adolescents (51% female; aged 10-14 years) with OSD. They underwent a 12- week intervention, initially (week 0-4) utilising an activity ladder paradigm designed to manage patellar tendon loading and pain. Subsequently, participants initiated progressive strength exercises (week 4-12), with a gradual return to sport (week 4-12). Primary outcome was self-reported improvement at 12 weeks, evaluated on a 7-point Likert-scale. Successful outcome was pre-specified as reporting ¡§much improved¡¨ or ¡§im- proved¡¨. Findings / Results: Adolescents reported an average 21 months („b12.5) pain duration. At 12 weeks, 88% completed the questionnaire with 80% report- ing a successful outcome, which increased to 87% at 6 months. At 12 weeks, 40% participated in regular physical activity with 16% back playing sport, these numbers increased to 78% and 64% at 6 months. 71% were satisfied with result of treatment and 96% would recommend it to a friend. Conclusions: Load management combined with progressive knee strengthen- ing has potential as a treatment for adolescents with OSD and should be ex- plored further. 176.
