A 24-year-old professional soccer player suffered an acute anterior cruciate ligament tear associated with a radiologically evident impression fracture of the lateral femoral condyle, the so-called "lateral femoral notch sign". Following MRI validation of the injury with detection of an additional lateral meniscus tear, arthroscopy was carried out 3 days after the injury. Due to the extended impression of about 5 mm, arthroscopically assisted closed reduction of the depression fracture was performed. A 3.2 mm tunnel was drilled at the lateral femoral condyle in a supero-inferior direction using an ACL tibial guide and the depressed area could be restored using an elevator. The resulting subchondral bone defect in the femoral condyle was filled with freeze-dried human cancellous bone allograft. As a one-stage procedure ACL reconstruction was carried out using a hamstring tendon technique. At 1-year follow up the patient has returned to full sporting function, including playing soccer with a radiographically reduced lateral femoral notch sign.
一名24岁的职业足球运动员遭受了急性前交叉韧带撕裂，同时伴有外侧股骨髁明显的影像学可见的嵌压骨折，即所谓的“外侧股骨切迹征”。在通过MRI证实损伤并检测到额外的外侧半月板撕裂后，于受伤3天后进行了关节镜检查。由于约5毫米的扩展嵌压，进行了关节镜辅助下的凹陷骨折闭合复位。使用前交叉韧带胫骨导向器在外侧股骨髁以上下方向钻一个3.2毫米的隧道，并使用骨膜剥离器恢复凹陷区域。股骨髁由此产生的软骨下骨缺损用冻干人松质骨同种异体骨填充。作为一期手术，采用腘绳肌腱技术进行了前交叉韧带重建。在1年的随访中，患者已恢复到完全的运动功能，包括踢足球，外侧股骨切迹征在影像学上有所减轻。
