INTRODUCTION: @entity130 @entity572 dislocations in @entity1 and adolescents require prompt concentric reduction. Incomplete reduction with or without retained osteochondral fragments has traditionally been addressed with open reduction. We report on the use of arthroscopy to remove loose bodies and reduce enfolded soft tissues to obtain concentric reduction in the pediatric and adolescent population. Specific note is made of underlying pathology and arthroscopic intervention. METHODS: After obtaining Institutional Review Board approval, we performed a retrospective review of @entity1 under the age of 19 who were treated with @entity572 arthroscopy following @entity572 reduction at a single @entity1 's hospital from 2006 to 2013. Clinic notes, operative reports, radiographic images, and arthroscopic photographs were reviewed. RESULTS: Seven @entity1 were identified (aged 8 to 17) who underwent @entity572 arthroscopy after a @entity572 . Intra-articular bone fragments were found in 6 of 7 @entity1 and 5 of 7 @entity1 had an incongruent @entity572 joint identified by imaging before surgery. The predominant pathology was @entity155 of a small bony fragment attached to the posterior capsular labral soft-tissue complex, which became enfolded and blocked reduction (5 of 7 @entity1 ). In all cases, the enfolded soft tissue was reduced without soft tissue or bone repair. @entity4713 were removed, and in 2 cases an avulsed ligamentum teres was debrided. Average follow-up was 10 months. No @entity2530 or recurrent instability was identified in any case. CONCLUSIONS: When incongruent @entity572 were arthroscopically evaluated after @entity130 , a consistent pattern of interposition of avulsed posterior bone fragment with attached capsule and labrum was found. Reduction of the capsulolabral complex without repair provided satisfactory short-term outcomes. Arthroscopic treatment of such cases was effective and well tolerated and could lead to considerably less postoperative @entity158 and surgical morbidity than open surgical treatment. LEVEL OF EVIDENCE: Level IV-case series.
