Travis M. Hendry, MD
Orthopedic Surgery
The knee joint is made up of the thigh bone (femur), the shin bone (tibia), the knee cap (patella), and a smooth lining called cartilage. In a healthy knee, the cartilage allows the bones of the joint to move against each other without friction or pain. Cartilage also helps absorb the stresses from normal daily activities. The meniscus are C-shaped structures made of cartilage in the knee that also protect the knee. The knee is supported by four main ligaments: the medial and lateral collateral ligaments on either side of the knee and the anterior and posterior cruciate ligaments inside the knee.
