Tibiofemoral joint

Question 1

what is the joint classification of the tibiofemoral joint?

Answer 1

uniaxial
modified hinge
synovial

Question 2

what are the articulating surfaces at the tibiofemoral joint?

Answer 2

.medial and lateral tibial plateaus
.medial and lateral femoral condyles

Question 3

what movements are permitted at the tibiofemoral joint?

Answer 3

flexion/extension
medial/lateral rotation

Question 4

how many ligaments are at the tibiofemoral joint?

Answer 4

10
+capsule

Question 5

What are the ligaments at the tibiofemoral joint?

Answer 5

1.) medial collateral
2.) lateral collateral
3.) anterior cruciate (ACL)
4.) posterior cruciate (PCL)
5.) oblique popliteal
6.) arcuate popliteal
7.) coronary
8.) patellomeniscal
9.) transverse
10.) meniscofemoral

Question 6

what does the medial collateral ligament do?

Answer 6

.limits valgus stress
.limits extension
.limits lateral rotation
.inner fibres blend with medial meniscus
.posterior medial fibres blend with capsule

Question 7

What does the lateral collateral ligament do?

Answer 7

.limits varus stress
.limits extension
.limits lateral rotation
.stronger then medial collateral
.does not attach the menisci or capsule

Question 8

is the lateral collateral ligament weaker or stronger than the medial collateral?

Answer 8

stronger

Question 9

what does the anterior cruciate ligament do?

Answer 9

.prevents tibia from moving anterior on femur
. limits hyperextension

Question 10

what does the posterior cruciate ligament do?

Answer 10

.prevents tibia from moving posterior on femur
.limits hyper flexion
limits hyperextension
.primary stabilizer at 90 degree knee flexion

Question 11

What ligaments are intra-capsular, exttrasynovial?

Answer 11

ACL, PCL

Question 12

what does the oblique popliteal ligament do?

Answer 12

.limits extension
.limits valgus on an extended knee
.reinforces posterior medial joint

Question 13

What does the arcuate popliteal ligament do?

Answer 13

.limits extension
.limits varus on an extended knee
.reinforces posterior lateral joint

Question 14

what does the coronary ligament do?

Answer 14

Holds menisci to tibial plateaus

Question 15

what does the patellomeniscal ligament do?

Answer 15

hold menisci to posterior patella

Question 16

what does the transverse ligament do?

Answer 16

holds two menisci together

Question 17

What does the meniscofemoral ligament do?

Answer 17

secures lateral meniscus to PCL and medial femoral condyle

Question 18

what nerves innervate the tibiofemoral joint?

Answer 18

branches of:
obturator
femoral
tibial &
common fibular nerves
