Lab Studies:
None
Other Studies:
Independent interpretation of knee radiographs obtained at initial presentation in the ED were concerning for possible subluxation of the fibular head, with no acute fracture noted. Given the concern for high ankle sprain, radiographs of the right ankle with stress views were obtained in clinic which demonstrated a congruent ankle mortise with no acute fracture or evidence of instability on stress views Case Photo #5 . In addition, an MRI of the right knee without contrast was obtained which demonstrated full thickness tearing of the posterior tibiofibular ligament from its fibular attachment, partial tearing of anterior tibiofibular ligament, a small effusion of the proximal tibiofibular joint, and slight subluxation of the fibular head consistent with tibiofibular joint instability, with no fracture or chondral injury Case Photo #6 [Photo7].
Consultations:
