Ligaments of the Hip & Knee

Question 1

Iliofemoral ligament

Answer 1

AIIS + intertrochanteric line of the femur

• prevents extension
• stabilises hip joint during standing

Question 2

Ischiofemoral ligament

Answer 2

body of the ischium + the greater trochanter of the femur

• prevents medial rotation

Question 3

Pubofemoral ligament

Answer 3

superior pubic rami + the intertrochanteric line of the femur

• prevents extreme abductions

Question 4

Ligamentum teres

*blood supply

Answer 4

(ligament of the head of femur)
acetabular fossa + the fovea of the femur

• weak and hase little influence on joint stabilization of hip.
• transmits the acetabular branch of the obturator artery into the head of femur

Question 5

Acetabular labrum

Answer 5

Around acetabulum

• deepens the socket to increase stability of the joint

Question 6

Tibial collateral ligament (MCL)

Answer 6

medial femoral epicondyle + medial condyle of tibia

• resists knee abduction (valgus stress - lateral force) (also flexion)

Question 7

Fibular collateral ligament (LCL)

Answer 7

lateral femoral epicondyle + head of fibula

• resists knee adduction (varus stress - medial force) (also flexion)

Question 8

Anterior cruciate ligament (ACL)

Answer 8

posterior intercondylar area + anterior tibia

• resists anterior sliding of the tibia on the femur

Question 9

Posterior cruciate ligament (PCL)

Answer 9

anterior intercondylar area of femur + posterior tibia

• resists posterior sliding of the tibia relative to the femur

Question 10

Lateral and medial menisci

Answer 10

tibial spine + tibial spine

• deepen the knee joint to
  resist rotational stress at the knee

Question 11

Bursae

Answer 11

reduce wear and tear and therefore, prevent damage and pain by being placed between structures that would otherwise rub against eachother

Question 12

Posterior (dorsal) interosseous sacroiliac ligament

Answer 12

Iliac tuberosity to the posterior surface of the sacrum

Prevents forward and downward dislocation of the sacrum from the ilia.
Assists to prevent sacral nutation

Question 13

Long posterior sacroiliac ligament

Answer 13

PSIS to Sacrum

Prevents extreme counter nutation

Question 14

Iliolumbar ligament

Answer 14

Iliac crest to the transverse processes of 5th lumbar vertebrae

Prevents forward dislocation of L5 on the downward sloping upper surface of the sacrum

Question 15

Sacrotuberous ligament

Answer 15

Lateral Sacrum to Ischial tuberosity

Prevents sacral nutation

Question 16

Sacrospinous ligament

Answer 16

Lateral Sacrum to the ischial spine

Prevents sacral nutation

Question 17

Inguinal ligament

Answer 17

ASIS to pubic tubercle

Doesn’t limit movement.
- Connects bone together

Question 18

Anterior longitundinal ligament

Answer 18

Runs along anterior surface of the vertebral column attaching to vertebra as it passes

Limits spinal extension

Question 19

Superior and Inferior interpubic ligaments

Answer 19

Pubic body + Pubic body

Helps bind the left and right hip bones together at the front across the pubic symphysis

Question 20

Sacrococcygeal Ligaments

Answer 20

Between inferior portion of sacrum and coccyx

Strengthens the joint between the sacrum and coccyx, preventing dislocation

Question 21

Transverse Acetabular ligament

Answer 21

Converts the body acetabular notch into a foramen by crossing where the acetabular labrum would be

Question 22

Supraspinous ligament of the spinal column

Answer 22

Runs along the superficial midline of the posterior vertebral column, attaching to each spinous process it passes

Limits extreme flexion of the vertebral column

Question 23

Which ligament prevents counter-nutation of the sacrum?

Answer 23

Long posterior sacroiliac ligament

Question 24

Which ligaments prevent nutation of the sacrum?

Answer 24

1. Posterior interosseous sacroiliac ligament
2. sacrotuberous ligament
3. sacrospinous ligament
