The Effectiveness of Using a Clinical Support Tool in Managing Adolescents with Non-Traumatic Knee Pain (MAP-Knee): protocol for a cluster-randomised superiority trial with delayed intervention and embedded realist evaluation

Abstract

Background Knee pain affects one in three adolescents, which makes it one of the most common pain sites. Guideline recommendations about the clinical selection of patients likely to benefit from interventions are unclear, which leads to treatment heterogeneity and the potential of wasted resources among adolescents with a good prognosis. In contrast, adolescents with a poorer prognosis may not receive sufficient care. A newly developed clinical decision-support tool (The MAP-Knee Tool) intends to support clinicians in engaging with patients and adjusting the clinicians’ evidence-based practices to accommodate patient preferences and treatment needs via a shared decision-making process. The aims of this trial are 1) to investigate the effectiveness of using a clinical decision-support tool (The MAP-Knee Tool) compared with usual care in adolescents with non-traumatic knee pain in reducing pain measured by KOOS-Child Pain after 12 weeks and 2) to investigate how the intervention worked, for whom, why and under which circumstances applying realist evaluation methodology.
