Knee dislocations, although a rare injury, is regarded as a severe event due to it‘s caused complications. If not diagnosed timely, popliteal artery injury causes tissue necrosis in the leg, commonly leading to amputation. It is difficult to estimate exact rate of knee dislocations, because almost as much as half patients present with spontaneous reduction. The most common reason of knee dislocation is a high-energy trauma, mainly caused by motor vehicle incidents, fall from significant height, but lately an increasing incidence of low-energy trauma caused dislocations is noted, especially among obese patients. This study presents literature review about knee dislocations, it‘s incidence in population, diagnostical challenges and the most common complications. We also present a case report: 63 years old patient was admitted to Repucblican Vilnius University Hospital with an ambulance after sustaining domestic trauma. The patient, while climbing the stairs, fell down and sustained a heavy blow to her left knee and right shoulder. After initial radiographic evaluation, she was diagnosed with anterior knee dislocation. As physical examination was made, it was noted the perfusion of the left is somewhat impaired, what led to suspicion of a possible popliteal artery rupture. After completing computed tomography angiography scan, the findigs showed circulation occlusion in the popliteal artery, and consequently the patient was urgently transferred to operating room in order to reconstruct the blood vessels. The following day didn‘t show any significant revewal of circulation and due to irreversible ischemia, as a life saving procedure leg amputation was permformed. |
