MSK- knee anatomy Flashcards
does the femur articulate with the fibula?
NO, the femur never articulates with the fibula
What is the largest and most complicated join in the body?
the knee joint
what does the knee consist of?
3 joints within a single synovial cavity
what 3 joints does the knee contain?
- medial condylar joint
- lateral condylar joint
- patellofemoral joint
what is the medial condylar joint?
Between the medial condyle of the femur and the medial condyle of the tibia
where is the lateral condylar joint located?
between the lateral condyle or the femur and the lateral condyle of the tibia
where is the patellofemoral joint located?
between the patella and the patellar surface of the femur
is the fibula directly involved in the joint?
no
what is one of the most frequently injured joints in the body?
knee joint
what kind of joint is the knee joint?
synovial hinge joint
what movements does the knee joint make?
- mainly flexes and extends
- it has a rotational component
function of the parellofemoral joint?
- articulation between the patella and femur
- main job is to increase the mechanical advantage of the quad muscle and protect the knee joint
what is the intercondylar eminence?
- double pointed prominence on the proximal surface of the tibial plateau
where is the medial and lateral condyle of the tibia located?
proximal end of the bone just below the tibial plateau
where is the tibial plateau located?
- what 3 things does it include?
proximal end including the medial and lateral condyles and intercondylar eminance
where is the tibial tuberosity located?
- what attaches to it?
large projection at the proxial end and anteror side where the patellar tendon attaches
what is the patella?
- what does it sit within?
triangular shaped seasmoid bone within the quadriceps tendon
what is the crucuate ligament?
- within the joint capsule
- the cross
- intracapsular ligaments
- names for their attachments
anterior crucuate ligament location?
- attaches to the anterior side of the tibia just medial to the medial meniscus
- attaches to the posterior side of the femur
anterior cruciate ligament function?
prevents anterior translation of the tibia on the femur
posterior cruciate ligament location?
- attaches to the posterior side of the tibia.
- attaches to the anterior femur
posterior cruciate ligament function?
prevents posterior translation of the tibia on the femur
Medial Collateral Ligament location?
- what is it attached to?
attached to the tibia and femur on the medial side of the knee joint.
attached to the medial meniscus, so injury to one can result in injury to both.
Lateral Collateral Ligament location?
- attached from the femur to the fibula on the lateral side of the knee
- Shorter and stronger than the MCL
