Objective: to Summarize the Anatomical Characteristics of Posterior Mediastinum of Knee Joint and Its Application in Arthroscopic Surgery, Especially in the Establishment of Trans-Posterior Mediastinum Access. Methods Fifty-Two Patients with Simple Posterior Mediastinum Were Selected. All Patients Underwent Arthroscopic Reconstruction and Were Divided into Two Groups According to Different Graft Materials: Autogenous Bone-Patellar Ligament-Bone Group (Group a, 26 Cases); Autologous Semitendinosus Tendon Group (Group B) 26 Cases. the Posterior Mediastinum Was Observed by Arthroscopy, and the Microscopic Findings and Gross Anatomical Results Were Compared and Analyzed. Results: the Blood Vessels and Nerves in the Upper Part of the Posterior Mediastinum Were Abundant and Were Close to Popliteal Artery At the Tibial Plateau Level. the Posterior Chamber of Knee Joint is Divided into Smaller Outer Chamber and Larger Inner Chamber. Knee Arthroscopy Should Bend Your Knees 90 Degrees When Establishing a Trans-Posterior Mediastinum Channel. It is Safer to Pass through from the Outside to the inside and from the Middle to the Lower Part of the Posterior Mediastinum. Conclusion: the Anatomical Structure of Anterior Cruciate Ligament is Complex, and There is No Obvious Relationship between the Curative Effect after Arthroscopic Anterior Cruciate Ligament Reconstruction and the Types of Graft Materials.
