FĂ©moro-tibial articulation: a hinge joint formed by the femoral condyles and the tibial plateaus, characterized by plane articular surfaces that are non-congruent, meaning they do not fit perfectly together.
FĂ©moro-patellaire articulation: a joint between the femoral trochlea and the posterior surface of the patella, also with plane surfaces that are non-congruent, resulting in a less precise fit.
Ligament croisé antérieur: a ligament that provides stability during knee flexion, preventing anterior displacement of the tibia relative to the femur.
Ligament croisé postérieur: a ligament that stabilizes the knee by preventing posterior displacement of the tibia, especially in flexion.
1. What is the primary function of the anterior cruciate ligament in the knee?
2. Which muscle from the ischio-jambiers group acts as a knee flexor?
3. What is hip flexion?
Knee joint articulations?
Femoro-tibial and femoro-patellar joints.
Main knee ligaments?
Anterior and posterior cruciate, collateral ligaments.
Knee stability source?
Ligaments and joint capsule.
Knee flexor muscles?
Hamstrings and gastrocnemius.
Hip flexion role?
Lifts thigh forward, greater with knee flexed.
Hip extension limits?
Limited by ischio-jambiers and ilio-femoral ligament.
