pain/injury w/torsion, feeling of instability, edema upon injury, often pop at the time of injury

23
Q

what is a common proximal influence for knee pain?

A

glut med weakness

24
Q

what is a common distal influence for knee pain?

A

pes planus

25
Q

if there is a valgus force at the knee, what injury may result?

A

ACL, MCL

26
Q

if there is a varus force at the knee, what injury may result?

A

PCL, LCL

27
Q

what is genu varum?

A

lateral angulation of the knees (knock knees)

28
Q

what is genu valgus?

A

medial angulation of the knees (bow legged)

29
Q

what is genu recurvatum?

A

hyperextension of the knees

30
Q

what conditions may result in genu recurvatum?

A

coxa valga (long leg) ispilaterally, coxa vara (short leg) contralaterally, tight gastroc, LACK OF DF (equina varus)

31
Q

what is patella alta?

A

high located patella

32
Q

what is patella baja?

A

low located patella

33
Q

what may result in patella baja?

A

tight patellar tendon

34
Q

what can we do for a tight patellar tendon?

A

superior patellar mobs

35
Q

what is tibial torsion?

A

twist in the tibial bone

36
Q

what is a Q angle?

A

the angle bw femur and the tibia

37
Q

is the Q angle usually larger in males or females?

A

females

38
Q

how do we measure the Q angle?

A

usually with observation

if measured, measure the angle from the ASIS to the mid patella

39
Q

t/f: an increase in Q angle can influence patellar problems

A

true

40
Q

what is normal patellar tracking?

A

6mm lateral
3mm medial

41
Q

what patellar tracking results from increased Q angle, genu valgus, weak VMO, weak hip abductors?

A

lateral tracking

42
Q

what patellar abnormality can cause wear on the undersurface of the patella and doesn’t allow good fluid exchange in the articular cartilage?

A

lateral tilt

43
Q

t/f: the length of the patella should be the length of the base to the tib tub

A

true

44
Q

what is the role of the patella?

A

to increase the efficiency of the quad by increasing the length for optimal contraction

45
Q

what can we strengthen and stretch for patellar tracking?

A

strengthen the quads and hip

stretch the HS

46
Q

how do we measure leg length with a tape measure?

A

from the ASIS to the medial malleolus

47
Q

what is involved in the lower quarter screen?

A

screening the adjacent joints and neurologic screen of myotomes, dermatomes, and DTRs

48
Q

what is normal open chain knee flexion?

A

132-141 degrees

49
Q

what is normal open chain knee extension?

A

50
Q

what is normal open chain tibial IR?

A

20-30 degrees

51
Q
