17
Q

What is the action of the biceps femoris

A

Flex and laterally rotate the leg, the long head also extends the femur

18
Q

What are the movements at the knee

A

Flexion/extension, varus /valgus, external/internal rotation

19
Q

What is the pes anserine

A

Common insertion of the gracilis, sartorius, and semitendinosus

20
Q

What is the attachment for the pes anserine

A

Medial tibia, deep fascia of the leg

21
Q

What are two roles of the pes anserine

A

For sure it helps stabilize the knee during partial flexion, it may also provide proprioceptive information for the coordination of the leg muscles

22
Q

What is a common pathology of the pes anserine

A

Pes anserine bursitis is a common source of knee pain in active young adults and osteoarthritic elderly

23
Q

What are the bones in the knee joint

A

Femur, tibia, patella. While the fibula is there, it is not real part of the joint.

24
Q

What is the role of the patella

A

Provide a lever or pulley surface for magnifying pulling forces across the knee

25
Q

What is interesting about the patella

A

It is a sesamoid bone and is not crucial for knee function

26
Q

What type of joint is the knee

A

Synovial joint between the femur and tibia, and between the patella and femur

27
Q

what is a common pathology of the knee

A

Chondromalacia

28
Q

Where is the anterior cruciate ligament

A

Anterior tibia to inner surface of lateral femoral condyle

29
Q

Where is the posterior cruciate ligament

A

Posterior tibia to inner surface of medial femoral condyle

30
Q

What is the role of the posterior and anterior crucial ligaments

A

To prevent posterior and anterior displacement of the femur on the tibia. The anterior limits hyperextension as well

31
Q

Where is the patellar ligament/tendon

A

A continuation of the quadriceps tendon, it continues anteriorly from patella to insert on tibial tuberosity

32
Q

Where is the fibular collateral ligament

A

lateral epicondyle of femur to head of fibula

33
Q

Where is the tibial collateral ligament

A

Medial femoral condyle to medial tibia, below the tibial condyle. attached to the medial meniscus and articular capsule

34
Q

What is the role of the collateral ligaments of the knee

A

Limit medial and lateral rotation as well as resist varus and valgus forces

35
Q

How many menisci are in the knee

A

There are 2 C-shaped menisci, medial and lateral

36
Q

What is The Terrible Triad

A

Torn ACL, MCL, and MM, usually from a lateral force to the knee when the foot is externally rotated

37
Q

What is the oblique popliteal ligament

A

An extension of the semimembranosus, this ligament strengthens the posterior articular capsule as well as forms the floor of the popliteal fossa

38
Q

What are the 4 bursas in the knee

A

Suprapatellar (between femur and quad tendon) pre patellar (housemaid’s knee), infrapatellar (clergyman’s knee), and semimebranosus (baker’s cyst)

39
Q

How does one “lock the knee”

A

In full extension, rotate the femur medially on the tibia

40
Q

How does one ‘unlock the knee’

A

the femur is laterally rotated on the tibia by the popliteus muscle, enabling normal function

41
Q

What are the risks and benefits to locking a knee

A

It allows stabilizing muscles to relax but puts extra compression on the medial and lateral menisci
