Q

What shape is the lateral condyle of the tibia? The lateral meniscus?

Q

What type of joint is the tibio-fibular joint?

A

Planar or arthrodial joint

23
Q

When is the knee capable of the most rotation?

A

Knee flexion

24
Q

When the knee locks in closed chain, the femur rotates (internally/ externally).

A

Internally

25
Q

To unlock the knee, the femur must (internally/externally) rotate in closed chain or the tibia must (internally/externally) rotate in open chain.

A

Externally; internally

26
Q

The inferior portion of the knee joint capsule is prolonged inferior laterally over the popliteus muscle to the head of the fibula forming the _________ ligament

A

Arcuate popliteal

27
Q

What are the intrinsic ligaments that are external and strengthen and supplement the joint capsule of the knee?

A
  1. Patellar lig
  2. LCL
  3. MCL
  4. Oblique popliteal lig
  5. Arcuate popliteal lig
28
Q

What lies between the patella ligament and proximal tibial so that the two structures can move freely without pain and also helps with flexion into extension?

A

Deep infrapatellar bursa

29
Q

About how long is the LCL? MCL?

A

5 cm; 8-9 cm

30
Q

What part of the LCL is considered to be part of the fibrous joint capsule of the knee?

A

Superiorly

LCL inferiorly separates by fatty tissue and splits the tendon of the biceps femoris muscle

31
Q

Why are injuries to the MCL frequently associated with injury to the medial meniscus and ACL?

A

The MCL attaches to the meniscus; stress on the MCL puts stress on medial meniscus from collateral blows

32
Q

What is clinically significant during post-MCL sprain recovery?

A

Bursa in MCL

33
Q

When are anterior fibers of the knee stressed? Posterior fibers?

A

Knee flexion; knee extension

34
Q

What ligament is an extension of semimembranosus tendon, travels superolaterally to insert into central part of capsule, and strengthens posterior capsule?

A

Oblique popliteal ligament

35
Q

True or False;

The synovial cavity of the knee is the largest one in the body and is due to the capsule reflecting around the cruciate ligaments.

A

True

36
Q

What bursa is an extension of the synovial capsule, between the femur and quadriceps tendon, and held in place by articulates genu muscle (pulls bursa superiorly to keep from getting damaged)?

A

Suprapatellar bursa

37
Q

What bursa lies between the tendon of the popliteus muscle and the lateral condyle of the tibia?

A

Popliteus bursa

38
Q

What bursa is an extension of the synovial capsule, and separates the tendon of the gastrocnemius muscle from the femur?

A

Gastrocnemius bursa

39
Q

What bursa separates the semimebranous m. from the tendon of gastroc m., and is the location of the popliteal or Baker’s cysts?

A

Semimembranosus bursa

40
Q

What bursa of the knee does not communicate with the synovial cavity, and separates the common common tendon of sartorial, semitendinosus, and gracilis from the proximal part of the medial tibial and MCL?

A

Anserine bursa

41
Q

What bursa is commonly affected by bursitis due to chronic weight bearing constant on the knees without knee pads

A

Subcutaneous pre patellar bursa

42
Q

What bursa allows skin to move over tibial tuberosity and withstands pressure during kneeling?

A

Subcutaneous infrapatellar bursa

43
Q

When is the ACL taut?

A

Extension

44
Q

When is PCL taut?

A

Flexion

45
Q

Is the ACL or PCL stronger?

A

PCL

46
Q

What supplies blood to the menisci?

A

Genicular branches of the popliteal artery

47
Q

Is the lateral or medial meniscus more mobile?

A

Lateral; medial meniscus is attached to MCL

48
Q

What nerves supply the knee joint?

A

Obturator, Femoral, Tibial, Common Fibular

49
Q

What makes up the superomedial border of the popliteal fossa? Superolateral? Inferomedial? Inferolatera?

A

Semitendionsus m. and tendon; Biceps femoris m.; Medial head of gastroc m.; Lateral head of gastroc m.

50
Q

What does the superficial popliteal fascia contain?

A
  1. Small saphenous vein
  2. Posterior femoral cutaneous n.
  3. Medial sural n.
  4. Lateral sural n.
51
Q

What makes up the floor of the popliteal fossa?

A
  1. Popliteal surface of femur
  2. Fascia of popliteus m.
  3. Oblique popliteal lig.
52
Q

What does the popliteal fossa contain?

A
  1. Popliteal artery
  2. Popliteal vein
  3. Branches off the sciatic nerve
53
Q

What vein starts medially in the ankle, moves a bit posterior as it travels up the thigh and ends in the femoral triangle?

A

Great saphenous v.

54
Q

What vein starts posterior to the lateral malleolus travels laterally and posteriorly up the leg, dives deep in the popliteal fossa, and drains into the popliteal vein?

A

Small saphenous v.
