Flashcards in Knee Joint Deck (18)
Tendon of the quadriceps muscles
Suspending the patella
Function: articulates only with the tibia
Weight bearing segment of the knee joint
Formed btwn the medial and lateral condyles of the femur and medial and lateral condyles of the tibia.
Suspened in the tendon of the quadriceps and is attached to the tibial tuberosity above
Below, by the the patellar ligament.
Dense c-shaped fibrous tissues with the medial meniscus, being larger and firmly attached to the medial condyle, provide stability to the joint.
Location: on each side,
Function: act to reinforce the joint capsul, help to provide strength to the knee joint
Proximal end of the medial (tibial) collateral ligament
Location: firmly attached to the medial epicondyle of the femur
Distal end of the medial (tibial) collateral ligament
Location: secured to the upper shaft of the tibia.
Medial collateral ligaments
Posterior fibers of this wide, triangular ligament are attached to the medial meniscus
Latera (Fibular) collateral ligament
Location: extends btwn the lateral epicondye of the femur and the head of the fibula.
Function: not attached to the lateral meniscus.
Anteriro tibiofibular ligament
Location: attached to the head of the fibula
Originates from the lateral condyle of the tibia.
Location: crosses to connect the femur and tibia.
Inside the knee capsule and named because of their attachment to the tibia.
Anterior Cruciate ligament
Location: attached to the anterior surface of the tibia, in front of the tibial spine
Curves backward to reach the lateral condyle of the femur, behind the intercondylar notch
Function: limiting extension of the lateral femoral condyle.
Posterior cruciate ligament
Location: attached btwn the tibial condyles, on the posterior surface and passes forward to reach the medial condyle of the femur in front of the intercondylar notch.
Cruciate ligaments (Function)
serve to prevent displacement of the femur from the tibial plateau.
Function: bind the two leg bones together, help resist the downward displacement of the fibula, when muscles of the fibula contract.
Damage to these ligaments, severe blow to the lateral knee,
Medial meniscus, medial collateral ligament and anterior cruciate ligament are often torn at the same time.
