Patellar Dislocation
Conditions
Brief summary
Do teen-age patients with a dislocated knee cap do better with or without a brace?
Detailed description
This study will look at two different ways to treat teen-age patients who have had a dislocation of their knee cap. Both groups will receive the physical therapy treatment for knee cap dislocation but one group will first be in a brace for a week and the other group will start moving in therapy right away.
Interventions
Groups will be compared to see if immobilization or early range of motion is better at returning to their sport after patellar dislocation.
