Answer 6

Triangular

Inferiorly

Question 7

Medial side of femoral and tibial condolences are

Answer 7

Oval

Question 8

Lateral side of femoral and tibial condyles are

Answer 8

Round

Question 9

Differences in shape allow?

Answer 9

Lateral rotation of the tibia under the femur at the end of extension of the knee

Question 10

Femoral aspect of the knee capsule is demarcated by ?

Answer 10

• proximal femoral condyles and i
• intercondylsr fossa posterioly
• patellar retinaculum anteriorly
• articular margin of the femur medially
• femur just proximal to the groove for the popliteus tendon laterally

Question 11

Tibial aspect of the knee capsule is demarcated by ?

Answer 11

M

Question 12

Knee capsule is a ——— structure

Answer 12

Dual-layered

Question 13

Knee capsule is ———- anteriorly and posteriorly, and laterally ————-

Answer 13

Thin

Thickened

Question 14

Laterally knee capsule is thickened by

Answer 14

Collateral ligament

Question 15

The outer layer of knee capsule consist of

Answer 15

Fibrous connective tissue

Question 16

The inner layer of knee capsule consists of

Answer 16

Synovial membrane

Question 17

Why there is no capsule over the patella?

Answer 17

Allowing the suprapatellar bursa to communicate with the joint

Question 18

On lateral side, there is

Answer 18

Tendon of vastus lateralis muscle

Question 19

On medial side, there is

Answer 19

Tendon of vastus medial is muscle

Question 20

Anterior knee capsule joint

Answer 20

Thick but deficient/absent anteriorly

Question 21

Why Is the capsule Thick but deficient/absent anteriorly

Answer 21

Allowing the synovial membrane to pouch upward beneath the quadriceps tendon forming
suprapatellar bursa

Question 22

Anterior capsule reinforced by

Answer 22

• quadriceps tendon
• patella
• ligamentum patella
• medial and lateral patellar retinacula
• expansion from the iliotibial tract(superior patella retinaculum)

Question 23

Posterior capsule reinforced by

Answer 23

1) semimembranosus tendon and its extension the (oblique popliteal ligament )
2) Arcuate popliteal ligament (passing above popliteus muscle)

Question 24

Laterally

Answer 24

Biceps femoris

Lateral rotation of the knee joint

Question 25

The major ligaments in the knee joints are:

Answer 25

1) patellar lig 2) collateral lig 3) cruciate lig

Question 26

Collateral structure laterally;

Answer 26

- Fibular collateral ligament - iliotibial tract - expansion from biceps femoris

Question 27

Medially structures (

Answer 27

- tibial collateral lig - pes anserinus - semimembranous tendon

Question 28

Shape of medial tibial collateral lig

Answer 28

Broad flat band

Question 29

medial tibial collateral lig extending from ———— and attach to ———-

Answer 29

- Medial epicondyle of of femur(below adductor tubercle) | - medial condyle of tibia and medial surface of shaft of tibia

Question 30

medial tibial collateral lig crossed by tendon of

Answer 30

- sartorius - gracilis - semitendinous(pes anserinus)

Question 31

Lateral fibular collateral lig shape

Answer 31

Thin, Round cord-like

Question 32

Lateral fibular collateral lig runs from ————- to——-

Answer 32

- lateral epicondyle of femur (above groove of popliteus) | - depression on lateral surface of fibular head

Question 33

Lateral fibular collateral lig primarily covered by

Answer 33

Tendon of the biceps femoris muscle

Question 34

Intracapsular lig

Answer 34

1) anterior cruciate lig | 2) post cruciate lig

Question 35

Intracapsular lig connect

Answer 35

Femur with tibia

Question 36

Function of collateral lig

Answer 36

Tight in extension Relaxed in flexion -prevent addiction/abduction of the knee joint

Question 37

Function of cruciate

Answer 37

Tight in both extension and flexion Relaxed at 30 degree of flexion -Prevent anterior and post lig displacement of tibia onto the femur

Question 38

Test for injury to cruciate lig

Answer 38

Anterior drawer test

Question 39

Anterior drawer test

Answer 39

Pull tibia forward, if it moves the lig has been torn

Question 40

ACL can be torn by

Answer 40

Hyper extension of knee joint | Large force of back the knee

Question 41

Most common mechanism of PCL damage

Answer 41

Dashboard injury

Question 42

Dashboard injury occur when

Answer 42

Knee is flexed
