Knee anatomy Flashcards
Does the femur articulate with the fibula at all
no
Largest most complicated joint in body
knee
3 joints of the knee synovial cavity
medial condylar, lateral condylar, patellofemoral joint
is fibula directly involved in the knee joint?
no
3 types on joint movement in knee
2 points of hinge, 1 planar gliding
What articulates in the patellofemoral joint
patellar and femur
patella main job in patellofemoral joint
increase the mechanical advantage of the quad and protect the knee
what is intercondylar eminence
double pointed prominence on the proximal surface of the tibial plateau
where is the medial and lateral condyle of the tibia
proximal end of the bone just below the tibial plateau
What does the tibial plateau include
the medial and lateral condyles and intercondylar eminence
what attaches to the tibial tuberosity
patella tendon
what tendon is the patella within
quadriceps tendon
cruciate ligaments are _________ ligaments
intracapsular
anterior cruciate ligament attaches to anterior side of ______
tibia just medial to the medial meniscus
anterior cruciate ligament attaches posterior side of
femur
anterior cruciate ligament prevents
translation of the tibia on the femur
posterior cruciate ligament attaches posterior side of
tibia
posterior cruciate ligament attaches anterior side of
femur
posterior cruciate ligament prevents
posterior translation of tibia on the femur
lateral collateral ligament attached from the ____ to ___ on the ____ side of the knee
femur to the fibula on lateral slide
lateral collateral ligament is ____ and _____ than the MCL
shorter and stronger
Medial contralateral ligament attached to ____ and _____ on the _____ side of joint
tibia and femur on the medial side
MCL also attached _____ which can be injured
medial meniscus
Deep layer of the MCL is continuous with
medial meniscus
2 most commonly torn ligaments of knee
MCL and ACL
2 that share common insertion onto the head of fibula
biceps tendon and LCL
What seperates the LCL and lateral meniscus
popliteal tendon
medial and lateral meniscus shape and what are they made of
half moon shape
made of fibrocartilage
function of medial and lateral meniscus
shock absorption
of medial and lateral meniscus which is torn more ofte n
medial
best imaging modality for menisci and ligament damage
MRI
where should be the focal zone where imaging the menisci
deeper in
dynamic imaging with _______ improves visualization of menisci
stress
What surrounds the sides of the joint but is absent on the frontal side
capsule
each side of the patella the capsule is strengthened by
vastus medialis and vastus lateralis
what makes up the diamond shape of the popliteal space
hamstrings and gastronemius
muscle causing extension of knee
quadricept only
lateral rotation of knee
biceps femoris only
what is arthroscopy
a surgical procedure that allows examination of the knee with an endoscope
