Tibiofemoral and patellofemoral joints
The knee is the largest synovial joint in the body. It consists of two articulations: tibiofemoral (weight-bearing) and patellofemoral.
Two C-shaped fibrocartilage discs that deepen the tibial articular surface:
Medial meniscus - C-shaped, attached to MCL (less mobile)
Lateral meniscus - O-shaped, more mobile
Clinical Pearl: The medial meniscus is more commonly torn due to its firm attachment to the MCL, making it less mobile during rotational injuries.
