Patellar incarceration with rotational dislocation in a medial femoral condyle fracture: A case report

Knee injuries in elderly patients can be challenging, particularly when complex fractures coexist with patellar dislocation. This case report describes a rare presentation of a 70-year-old female with a partial articular fracture of the medial femoral condyle and an incarcerated rotational patellar dislocation following a fall. The patient, with a history of hypertension and type 2 diabetes mellitus, presented with severe knee pain and swelling. Radiographs and computed tomography (CT) confirmed patellar rotation and entrapment within the fracture site. She underwent open reduction and internal fixation, achieving successful anatomical reduction. Postoperatively, the patient developed seizures and hyperglycemia, and a brain CT revealed an acute infarct. This case highlights the complexities of managing knee injuries in elderly individuals with comorbidities and emphasizes the need for careful clinical assessment, precise surgical intervention, and vigilant post-operative monitoring to address both orthopedic and medical complications.
