Knee Practical

Question 1

Hip (adductor/abductor) weakness can cause compressive loads on the patellofemoral joint. In weight bearing, this will cause increased hip adduction and internal rotation which can cause a compressive load in the patellofemoral joint.

Answer 1

abductor

Question 2

What muscle length test tests for the flexibility of the rectus femoris?

Answer 2

Prone knee flexion (ely test)

Question 3

What do you compare the prone knee test to, to assess the flexibility of the rectus femoris?

Answer 3

Supine knee flexion

Question 4

If there is a difference between the measurements in prone knee flexion and knee flexion in supine what does that mean?

Answer 4

It means that the rectus femoris is tight

Question 5

If I have problems flexing my knee, what would you test for in terms of ROM, MMT, and muscle length tests?

Answer 5

ROM - Knee flexion. MMT - Knee flexion. Muscle length test - Prone knee flexion.

Question 6

What are two good stretching exercises to improve knee flexion with sets and reps?

Answer 6

Normal standing quad stretch: 3x30 seconds.

Prone quad stretch with band or added over pressure: 3x30 seconds

Question 7

What are two good strengthening exercises to improve knee flexion strength with sets and reps?

Answer 7

Question 8

If I have problems extending my knee, what would you test for in terms of ROM, MMT, and muscle length tests?

Answer 8
