knee joint

Question 1

tibiofemoral articulations

Answer 1

medial + lateral femoral condyles articulate with tibial condyles

Question 2

patellofemoral articulation

Answer 2

anterior aspect distal femur articulates with patella

Question 3

blood supply

Answer 3

genicular anastomoses around knee, supplied by genicular branches of femoral and popliteal arteries

Question 4

nerve supply

Answer 4

femoral
tibial
common fibular

Question 5

menisci

Answer 5

fibrocartilage structures

medial + lateral

Question 6

menisci functions

Answer 6

deepen articular surface of tibia –> increase stability

act as shock absorbers by increasing surface area to dissipate forces

Question 7

what is medial meniscus attatched to

Answer 7

fixed to tibial collateral ligament

damage to this ligaent often results in medial meniscal tear

Question 8

bursae of knee joint

Answer 8

suprapatellar bursa
prepatellar bursa
infrapatellar bursa
semimembranosus bursa

Question 9

patellar ligament

Answer 9

continuation of quadriceps femoris

attatches to tibial tuberosity

Question 10

collateral ligaments

Answer 10

2 strap-like ligaments

stabilise hinge motion and prevents excessive medial or lateral movement

Question 11

cruciate ligaments

Answer 11

connect femur and tibia, in doing so cross over eachother creating an X

Question 12

anterior cruciate ligament

Answer 12

prevents anterior dislocation of tibia onto femur

Question 13

posterior cruciate ligament

Answer 13

prevents posterior dislocation of tibia onto femur

Question 14

knee extensors

Answer 14

quadriceps femoris

Question 15

knee flexors

Answer 15

hamstrings
gracilis
sartorius
popliteus

Question 16

knee lateral rotators

Answer 16

biceps femoris

Question 17

knee medial rotators

Answer 17

semimbranosus 
semitendinosus 
gracilus 
sartorius
popliteus
