Anterior Instability
Epidemiology
Traumatic initial cause in 95%
M:F 2:1
Age of initial dislocation inversely related to recurrence rate
- patients younger than 20 have a redislocation rate of 90%
- between 20 - 40 years, redislocation rate of 60%
- patients > 40 years have a 10% rate of dislocation but a higher rate of cuff tears (up to 40% in patients > 60yrs)
