Ligaments of the Knee & Leg Flashcards
Fibrous capsule of knee
attachments- from the margins of the femoral condyles to the margins of the tibial condyles
Tibial (medial) collateral
attachments- from the medial epicondyle of the femur to the medial condyle & shaft of the tibia
function- stabilizes the medial aspect of the joint (prevents abduction of the tibia)
Fibular (lateral) collateral
attachments- from the lateral epicondyle of the femur to the head of the fibula
function- stabilizes the lateral aspect of the joint (prevents adduction of the tibia)
Anterior cruciate (L. crux, cross)
attachments- from the medial part of the anterior intercondylar area of the tibia to the posterior part of the medial surface of the lateral condyle of the femur
function- prevents posterior displacement of the femur on the tibia and hyperextension of the knee
Posterior cruciate
attachments- from the posterior intercondylar area of the tibia to the lateral surface of the medial condyle of the femur
function- prevents the anterior displacement of the femur on the tibia
Menisci (Gr. meniskos, crescent)
- Medial
attachments- anterior & posterior regions of the intercondylar area of the tibia & fibrous capsule at the tibial collateral ligament - Lateral
attachments- anterior & posterior regions of the intercondylar area of tibia
Patellar ligament
attachments- from the apex of the patella to the tibial tuberosity
function- resists knee flexion
Crural interosseous membrane
attachments- from interosseous border of the tibia to the interosseous border of the fibula
