“…[2][3][4] Despite the numerous studies of the natural history after an initial traumatic anterior dislocation, the exact incidence of recurrent instability remains uncertain, 2,4,5 with rates quoted ranging from as low as 17% 6 to close to 100%. 2,[7][8][9][10] Many of the series which describe a high incidence have been drawn from selective populations, such as patients presenting to sports injury clinics and in military cadets, 7,11 and may therefore be unrepresentative of the general population. There may also be a substantial pool of individuals who never seek medical advice, either because they sustain an isolated dislocation, become occasional dislocators, or are relatively asymptomatic and do not want surgical intervention.…”
