Radiographic identification of the anatomic attachment sites of knee ligament structures allows surgeons to obtain an accurate diagnosis and treatment of knee injuries. The previous studies have provided quantitative and radiographic data for other ligaments, which has aided surgeons in intraoperative tunnel placement and postoperative assessment of anatomic knee ligament reconstructions. The qualitative and quantitative anatomic descriptions of the anterior and posterior ligament complexes of the PTFJ are currently becoming better understood due to recent focus on this topic. However, quantitative guidelines for radiographic identification of the anterior and posterior ligament bundles of the PTFJ are still lacking in the current literature.
Due to the complex anatomy of the posterolateral corner of the knee, proper identification of tunnel placement is critical to properly diagnose and treat associated injuries to this area. Therefore, the purpose of this study was to provide reproducible, quantitative descriptions of radiographic landmarks identifying the anterior and poste- rior ligament complexes of the proximal tibiofibular joint to guide intraoperative tunnel placement and postoperative assessment of an anatomic proximal tibiofibular joint reconstruction.
