lecture 22 Flashcards
what is the largest and most superficial joint in the body
knee joint
what are the 3 articulations of the knee joint
lateral femorotibial
medial femorotibial
patellofemoral
what bone is not involved in the knee joint
finula
what is the cclassifiation of knee joint
modified hinge, synovial joint, sometimes reffered to as a bicondylar joint
what fibrocartilaginous plates called menisci do
what rest on the tibial platue and help to deepen the articular surface
what are the intrinsic ligaments of the knee joint
patellar ligament
medial/tibial collateral ligament
oblique popliteal ligament
arcuate popliteal ligament
extrinsic ligamnets of knee joint
lateral/ fibular collateral ligament
anterior cruciate ligament
posterior cruciate ligament
what are cruciate ligaments often reffered to as
internal ligaments
where are the cruciate ligaments located
within the fibrous joint capsule but excluded from the synovial capsule
where does the anterior cruciate ligament attach
the anterior aspect of the intercondylar eminence and passes to the lateral femoral condyle
where does the posterior cruciate ligament attach
on the posterior aspect of the intercondylar eminence and passses to the medial femoral condyle
what does the anterior cruciate ligament do
prevents the tibia from moving anteriorly under the femur and is tight on knee extension
how do you assess the stability of the ACL after a knee injury
the anterior drawer test
what does the posterior cruciate ligament do
prevents the tibia from moving posteriorly under the femor and is tight on knee flexion
what test can assess the stability of the PCL after a knee injury
posterior drawer test
