Fig. 1Initial femur anteroposterior (A) and lateral (B) image show a right femoral shaft fracture. And initial knee anteroposterior (C) and lateral (D) image without a sign of fracture.
Fig. 2Postoperative anteroposterior (A) and lateral (B) image show a fixed state of fracture with antegrade intramedullary nail.
Fig. 3Axial (A) and coronal (B) image of computed tomography demonstrate a small bony fragment on the medial aspect of the lateral femoral condyle. And coronal (C), sagittal (D), axial (E), and oblique coronal (F) images show avulsion fracture at the femoral attachment of the anterior cruciate ligament (white arrows).
Fig. 4Arthroscopic images show a grossly normal looking anterior cruciate ligament (A) and an intact anterior cruciate ligament with applied tension using probe (B) (black arrows).
Fig. 5Postoperative 6 months femur anteroposterior (A) and lateral (B) image show healed femoral shaft fracture after the internal fixation. And postoperative 6 months knee anteroposterior (C) and lateral (D) image show no abnormal findings.
