Knee Anatomy

Knee Anatomy: Bones, Ligaments, Muscles, and Functions

The knee is a modified hinge-type synovial joint that connects the thigh to the lower leg. It consists of three principal bones: the femur (thighbone), tibia (shinbone), and patella (kneecap). The nearby fibula provides attachment points for supporting tissues but is not part of the knee’s main articulations. These are the tibiofemoral joint, where the femur meets the tibia, and the patellofemoral joint, where the patella meets the femur. This arrangement allows the knee to Read more
