Extracapsular ligaments stabilizing the knee include ________.?

Question

a. the patellar ligament extending from femur to patella

b. lateral and medial collateral ligaments preventing lateral or medial angular movements

c. cruciate ligaments, which help secure the articulating bones together

d. the oblique popliteal crossing the knee anteriorly

Answer 1

Four ligaments are present in the knee joint, the medial collateral ligament, lateral collateral ligament, anterior cruciate ligament, and posterior cruciate ligament. These ligaments provide strength to the knee joint.

The medial collateral ligament is located at the inside of the knee joint. It extends from the medial femoral epicondyle to the tibia. This ligament prevents excessive abduction of the knee.

The lateral collateral ligament is located at the outside of the knee joint. It extends from the lateral femoral epicondyle to the head of the fibula. This ligament prevents excessive adduction of the knee.

The anterior cruciate ligament extends posterolaterally from the tibia and inserts on the lateral femoral condyle. This ligament prevents excessive posterior movement of the femur on the tibia.

The posterior cruciate ligament extends anteromedially from the tibia posterior to the medial femoral condyle. This ligament prevents excessive anterior movement of the femur on the tibia.
