About

Objective: To examine the potential of dextrose injection versus lidocaine injection versus supervised usual care to change pain/function/activity levels in adolescent athletes with Osgood-Schlatter Disease (OSD).

Full description

Patients and methods: Girls ages 9-15 years old and boys ages 10-17 years old will be assigned to either therapist-supervised usual care, or to double-blind injection of 1% lidocaine solution with or without 12.5% dextrose. Injections will be administered monthly for three months. All subjects will then be offered dextrose injections monthly as needed. Change in the Nirschl Pain Phase Scale (NPPS) will serve as the primary outcome measure.
