Summary
This study follows 201 healthy teens aged 12-14 over two years to see if playing only one sport year-round leads to hip impingement (FAI), a condition where hip bones rub together. Participants get MRI scans and fill out questionnaires. The goal is to understand if early sport focus causes hip damage and to inform prevention strategies.
