<B>Background:</B> Traumatic anterior shoulder instability has a wide spectrum, from a definite dislocation to a subtle instability. Most patients have the sensation that their shoulders slipped out at the time of instability events. There is, however, another category of patients who are not aware of slipping out or instability of the shoulder. The purpose of this study was to evaluate the characteristics of such patients who have not recognized traumatic anterior instability.<BR><B>Methods:</B> Seventeen patients who were not aware of traumatic anterior shoulder instability were operated on between 2007 and 2011. There were 16 men and 1 woman, and the mean age at surgery was 18.8 years old. All patients except one case, engaged in contact sports or overhead sports activities. We investigated their clinical history, and both imaging and arthroscopic findings of their shoulders.<BR><B>Results:</B> Chief complaints of the patients were recurrent shoulder pain during sports activities after a history of trauma. None of them felt that their shoulder had anterior instability or got unstable after the injury. Positive anterior apprehension test and positive relocation test led us to a suspicion that patients may have had recurrent anterior subluxation of the shoulder. CT and MR arthrogram revealed that there was evidence of anterior instability such as Bankart lesion and/or Hill-Sachs lesion. Arthroscopic examination confirmed these findings and anterior stabilization procedure yielded favorable outcomes.<BR><B>Conclusion:</B> Attention should be paid not to miss the diagnosis of unstable painful shoulder in young athletes.
