Arcuate popliteal ligament

19
Q

What are the intrinsic ligaments of the knee:

20
Q

The medial colateral ligament is _____

A

wider

21
Q

The MCL attaches to the medial ____

A

meniscus

22
Q

The MCL works with the ACL to stop the ____ moving too far forward

A

The MCL works with the ACL to stop the tibia moving too far forward

23
Q

The lateral colateral Ligament is separated from lateral meniscus by _____tendon

A

popliteal tendon

24
Q

Both the LCL and MCL are taut in _______

A

Extension

25
Q

Cruciate ligaments stop excessive _____/_____ displacement

A

Cruciate ligaments stop excessive anterior/posterior displacement

26
Q

The ACL is prone to injury in _____ and ______ knee

A

The ACL is prone to injury in flexed and rotated knee

27
Q

The __ assists internal rotation of femur and contributed to locking

A

ACL

28
Q

The PCL is taut in full ____

A

flexion

29
Q

The mensici allow separate movements in the knee joint capsule

during rotation the menisci hug the ______ end of the femur

A

inferior

30
Q

Ligament and meniscal damage is most common in ______ sports

A

twisting

31
Q

The ______ muscle locks and unlocks the knee in conjunct rotation

A

Popliteus

“pops” the knee out and mobile

32
Q

Adjunct is when your knee is flexed and can do internal and external rotation, which muscles allow this?

A

semitendinosus and Biceps femoris

33
Q

The medial condyle is ______- which helps with the passive locking mechanism

A

longer

34
Q

The femoral artery goes through the adductor ____

A

hiatus

35
Q

The branches that supply the knee are called _____

A

genicular arteries

lots of them, lots of blood supply

36
Q

If contact is with the lateral condyles of the knee it is called genu ____

A

valgum

37
Q

The patella increases the pull of the ____ along the long axis of the lower limb - it makes contact with the ____ tuberosity (via patella ligament) at a ____angle = more leverage

A

The patella increases the pull of the quads along the long axis of the lower limb - it makes contact with the tibial tuberosity at a greater angle = more leverage

38
Q

Due the oblique angle of the femur, the tendency is for the patella to be pulled ______

A

Due the oblique angle of the femur, the tendency is for the patella to be pulled laterally

39
Q

What are the factors that prevent the patella from displacing laterally?

A

active contraction of vastus medialis

medial patella retinaculum

Raised lip on lateral femoral condyle (the lateral condyle of the femur has an anterior projection)
