16
Q

What are the attachments of the fiberous capsule of the knee?

A

margins of the femoral condlyes to the margins of the tibial condyles

17
Q

Tibial/ MedialCollateral Lig. attachments

A

Medial condyle of the tibia to medial condyle /shaft of femur

(deep to sartorius and pes anserinus)

18
Q

Fibular (lateral) collateral lig. attachments

A

Lateral condyle of femur to the head of the fibula

19
Q

Tibial/ MedialCollateral Lig. functions

A

resists valgus forces @tibiofemoral joint , stabalizing medial aspect of joint

20
Q

Fibular (lateral) collateral lig. function

A

Resists varus forces @tibiofemoral joint and sab lat. aspect of joint

21
Q

ACL : Anterior cruciate lig. attachments

A

Anterior medial intercondylar are of the tibia to the lateral condyle of the femur

Ant. Medial -> Post. Lat

22
Q

ACL functions

A

Prevents ant. displacement of tibia
prevents post . dis. of femur

prevents HYPERextension and limits ROTATION of tibia on femur

23
Q

PCL: Posterior Cruciate lig. attachments

A

from post. medial intercondylar space of the tibia to lateral side of medial condyle of the femur

Post. Medial -> Ant. lat. of medial condyle

24
Q

Medial minisci attachments

A

medial intercondylar area of tibia + fibrous capsule at the medial collateral lig.

25
Q

Lateral minisci attachments

A

lateral intercondylar area

26
Q

Medial petellofemoral lig. attachments

A

50 % of medial patella to the medial epicondyle of the femur

27
Q

Medial petellofemoral function

A

Prevents lat. displacement of the patella

28
Q

Crural interosseous membrane attachments of tibia and fibula

A

from interosseous border of the tibia to the interosseous border of the fibula

29
Q

What is the only lig. that doesn’t attach to the tibia

A

Lat. collateral lig. : attaches to the fibula

30
Q

In addition to the ACL, what is also injured during a hyperextension injury?

A

Post. ligaments of the knee

31
Q

Which Femoral condyle is larger and what movement does it cause the tibia to do at terminal extension of the knee?

A

Medial femoral condyle is larger: causes tibia to ER which creates bony congruency and ligamentous tension

32
Q

Which menisci is larger and is in a C shape and attaches to a collateral lig.

A

Medial meniscus attaches to MCL + semimembranous

33
Q

Why might resisted knee flexion be a contraindication after a MCL/ medial menisci tear?

A

Because the medial meniscus attaches to the MCL and hamstring semimembranousus muscle at the posterior horn

34
Q

Where is BF the greatest in the menisci?

A

BF is the greatest in the peripheral (outside) the menisci, less on the inside

35
Q

Compression at the knee is increased by what 2 things?

A
  1. Quad muscle force/activation
  2. Deg. of knee flexion
36
Q

What are some anatomical factors that predispose ind. to patellar instability?

A
  1. Medial patella femoral lig. reticular deficiency
  2. Shallow trochlear groove (Trochlear dysplasia)
  3. Flat patella
  4. Petella alta (high petalla)
