Clinical Question: To report the effect of age on number of instability events before physician consult, rate of surgical stabilization, recurrent instability and progression to osteoarthritis (OA) in patients <40 years.
Bottom Line:  Younger patients – particularly those in groups <15 & 16-20 years-old – were more likely to have experienced multiple instability events at time of initial consult, require surgery and experiences recurrent instability. 
Points to Consider: Descriptive epidemiologic study. 654 patients with mean follow-up of 11.1 years. Patients 16 to 20 years old had the highest rates of surgical intervention (40.4%) and recurrence after surgery (24.8%). Those in the 31 to 40 yo group were significantly more likely to develop symptomatic OA (15.6%) than all other age groups.
