the tibiofemoral joint. A premeniscal capillary network arising from the branches of these arteries originates within the synovial and capsular tissues of the knee along the periphery of the menisci. The peripheral 10% to 30% of the medial meniscus border and 10% to 25% of the lateral meniscus are relatively well vascularized, which has important implications for meniscus healing (Figure 6).12,3..
to the peripheral border. These fibers blend the ligamentous connections of the meniscal horns to the tibial articular surface (Figure 3).10,27,49,156 In the most superficial region of the menisci, the type I fibers are oriented in a more radial direction. Radially oriented tie fibers are also present in the deep zone and are interspersed or woven between the circumferential fibers to provide st..
horn is attached to the posterior intercondylar fossa of the tibia between the lateral meniscus and the posterior cruciate ligament (PCL; Figures 1 and 2B). Johnson et al reexamined the tibial insertion sites of the menisci and their topographic relationships to surrounding anatomic landmarks of the knee.82 They found that the anterior and posterior horn insertion sites of the medial meniscus we..
Alice J. S. Fox, MSc,* Asheesh Bedi, MD, and Scott A. Rodeo, MD Context: Information regarding the structure, composition, and function of the knee menisci has been scattered across multiple sources and fields. This review contains a concise, detailed description of the knee menisciincluding anatomy, etymology, phylogeny, ultrastructure and biochemistry, vascular anatomy and neuroanatomy, biomec..
