Abstract: Objective    To provide anatomical basis for the diagnosis and treatment of tibial collateral ligament (TCL) and medial meniscus (MM) injuries under arthroscopy.    Methods    Eighteen adult cadaver knee specimens were dissected to observe the anatomical morphology of TCL and MM and the relationship between them.     Results    Deep layer of TCL formed a wide but firm connection between the posterior oblique ligament and the anterior medial capsule and the body and posterior angle of the MM. The contact length and contact area of the two were (8.12±0.44) mm and (36.39±4.45) mm2, respectively, which could maintain the stability of the MM during flexion and extension of the knee.    Conclusions    The TCL and MM are important components for the stability of medial knee joint. In-depth knowledge of their morphological characteristics are of great significance for the diagnosis, treatment and anatomical repair of TCL and MM injuries under arthroscopy.
