Q

What are the functions of the cruciate ligaments?

A

Primarily stabilizers of the joint
Provide stability for/prevent medial and lateral bending
Prevent hyperextension of the joint
Provide rotational stability
Cranial cruciate prevents cranial displacement of the tibia during weight bearing

Q

What are the attachments of the medial meniscus?

A

Cranial and caudal tibial attachment

17
Q

What are the attachments of the lateral meniscus?

A

Cranial and caudal tibial attachment

Attachment on the fibula (meniscofemoral ligament)

18
Q

Which meniscus is the most likely to be damaged?

A

Medial

19
Q

What is the breakdown of the nourishment of the menisci?

A

10-15% of the outer menisci are nourished by the joint capsule
The remaining are nourished with synovial fluid

20
Q

What are functions of the menisci?

A

Fill the incongruence between the femur and tibia
Provides joint stability
Load transfer/shock absorber
Disperse the synovial fluid
Prevents the synovial membrane from becoming entrapped between the articular surfaces of the femur and the tibia

21
Q

What makes up the femoral triangle?

A

Caudal part of sartorious
Pectineus
Inguinal ligament
