26
Q

ACL (info)

A

is taut in full extension; prevents anterior displacement of the tibia

27
Q

PCL attachment

A

attached to the inner surface of the medial femoral condyle and the posterior intercondylar area of the tibia

28
Q

PCL (info)

A

is taut during flexion; prevents posterior displacement of the tibia

29
Q

To unlock the knee to permit flexion from the locked position, the femur must rotate ______ on the tibia (or the tibia rotate ______).

A

laterally; medially

30
Q

the muscle to aid in the unlocking of knee extension

A

popliteus

31
Q

Compare the strength of knee flexion with the ankle dorsiflexed and plantarflexed. Why would you expect a difference?

A

The gastrocnemius, a knee flexor, is weaker (on slack) with the ankle plantarflexed. This position could be utilized if you wish to test the hamstrings while minimizing the effect of the gastrocnemius.

32
Q

Test the strength of your partner’s quadriceps in the sitting position. Compare the strength when the hip is flexed (when your partner sits leaning forward) or extended. Why could there be a difference?

A

With the hip flexed, the rectus femoris is put on slack, and is therefore in a weaker position.

33
Q

Genu recurvatum increases….

A

lumbar lordosis

34
Q

Meniscus

A

increase the shock absorption

triple the contact surface area

35
Q

talocrucal joint (artho)

A

tibia, fibula, and talus
concave tib/fib
convex talus

36
Q

closed chain pronation

A

eversion (calcaneus), adduction (talus), plantar flexion (talus), flexion of knee (stable forefoot)

37
Q

closed chain supination

A

inversion (calcaneus), abduction (talus), dorsiflexion (talus), extension of knee (stable forefoot)

38
Q

open chain pronation

A

eversion (calcaneus), abduction (forefoot), doriflexion (forefoot) (stable talus)

39
Q

open chain supination

A

inversion (calcaneus), adduction (forefoot), plantar flexion (forefoot) (stable talus)

40
Q

50
Q

Hallux Valgus

A

Bunion

displacement of the 1st MTP join by the displacement of the flexor and extensor tendors

51
