Acute Thrombotic Occlusion of the Popliteal Artery following Knee Dislocation: A Case Report of Management, Local Unit Practice, and a Review of the Literature

Immediate identification and management of an open posterior knee dislocation: Important lessons from a case report

Traumatic knee dislocation represents a rare event, contributing to less than 0.02 % of all orthopedic trauma and 0.05 % of joint dislocations, respectively. It is critically important to recognize, identify, and appropriately manage such cases as 'time' is implicated as an outcome-determining factor. Thus, such cases warrant quick consideration and appropriate management to mitigate the possibility of neurovascular damage and long-term sequelae. We report a case of a 59-year-old man struck by a motor vehicle in a remote rural community in northern Mexico managed with external fixation 16 h after the initial trauma, and later resulting in a supracondylar amputation. The authors of this case report underline the importance of timely intervention strategies when faced with such cases of knee dislocation and promote enhanced training of peripheral trauma-care providers to help improve patient outcomes.

Acute Popliteal Artery Thrombosis Resulting From a Closed Comminuted Tibia Fracture: A Case Report

Acute popliteal artery thrombosis is a rare and limb-threatening traumatic event. It can lead to soft-tissue necrosis or even amputation of the lower limb. In patients suffering from trauma around the knee joint, the clinician should be highly vigilant to risk of popliteal artery acute thrombosis. It is essential to detect and treat acute popliteal artery thrombosis timely for limb salvaging. We present a case of acute popliteal artery thrombosis resulting from a closed comminuted tibia fracture and discuss its injury mechanism, diagnostic methods, and treatment measures.
