knee

Question 1

how knee stailised

Answer 1

menisci to deepen tibial articulation, capsule , ligaments, muscles

Question 2

which ligaments

Answer 2

intracapsular- cruciate
capsule- oblique popliteal
extracapsular-collateral

Question 3

describe path of cruciate

Answer 3

PAMs APpLes
• Posterior passes Anterior inserts Medially
• Anterior passes Posterior inserts Laterally

Question 4

compare cruciate ligements

Answer 4

ACL- weaker of the two
• Relatively poor blood supply
• Limits anterior movement of Tibia on Femur
• PCL- stronger of the two
• Limits posterior movement of tibia on femur
• In weight bearing flexed knee- PCL is the main stabilizer

Question 5

role medial/lateral collateral

Answer 5

latera- varus forces

medial- valgus forces

Question 6

flexion knee

Answer 6

• Hamstrings: Biceps femoris, semimembranosus, semitendinosus

SCIATIC

FEMORAL

inserts into tibial tuberosity

Question 8

medial rotation knee

Answer 8

Question 27

popliteal fossa

Answer 27

Superomedial border – semimembranosus. Superolateral border – biceps femoris. Inferomedial border – medial head of the gastrocnemius. Inferolateral border – lateral head of the gastrocnemius and plantaris.
