Abstract
IntroductionKnee dislocation is an unusual condition, and can have catastrophic consequences, such as vascular and neurological complications, in addition to the ligament injuries. ObjectiveThe aim of this study is to analyse the effectiveness of a protocol of early diagnosis of vascular injuries associated with knee dislocations. Materials and methodsA retrospective study was conducted which included acute knee dislocations treated in our institution, with a minimum of 12 months follow-up, between 1999-2010. A diagnostic protocol based on physical examination and ankle-brachial index was used in order to detect vascular injuries. ResultsTen dislocations, 30% with popliteal artery injury, were diagnosed early and received emergency treatment within 8hours. There were associated neurological injuries in two patients. There were no amputations. ConclusionsThe systematic use of this protocol has avoided consequences of late diagnosis and has drastically reduced the abusive use of invasive tests, such as arteriography.
