  • Title: [Vascular injuries associated with dislocation of the knee: diagnosis protocol].
    Author: López-Hualda A, Valencia-García H, Martínez-Martín J.
    Journal: Rev Esp Cir Ortop Traumatol; 2012; 56(4):260-6. PubMed ID: 23594843.
    Abstract:
    INTRODUCTION: Knee dislocation is an unusual condition, and can have catastrophic consequences, such as vascular and neurological complications, in addition to the ligament injuries. OBJECTIVE: The aim of this study is to analyse the effectiveness of a protocol of early diagnosis of vascular injuries associated with knee dislocations. MATERIALS AND METHODS: A 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. RESULTS: Ten dislocations, 30% with popliteal artery injury, were diagnosed early and received emergency treatment within 8 hours. There were associated neurological injuries in two patients. There were no amputations. CONCLUSIONS: The systematic use of this protocol has avoided consequences of late diagnosis and has drastically reduced the abusive use of invasive tests, such as arteriography.
