Chapter 15 Knee Conditions

3) The function of the ______ is to resist valgus and rotational forces acting on the knee. a) MCL b) LCL c) ACL d) PCL

A. MCL

10)Which of the following conditions warrants activation of EMS? a) patellar dislocation b) knee dislocation c) tear of the ACL d) all of the above

b) knee dislocation

2) The anterior cruciate ligament a) resists posterior displacement of the tibia on the femur b) is the primary stabilizer of the knee c) prevents anterior displacement of the tibia on the femur d) resists varus and valgus forces to the knee

c) prevents anterior displacement of the tibia on the femur

8) A sign associated with a sprain of the LCL of the knee is a) significant effusion b) pain on the medial joint line c) significant joint instability d) hearing a "pop" accompanied by sharp lateral pain

d) hearing a "pop" accompanied by sharp lateral pain

12)True or False? The medial meniscus has an attachment to the medial collateral ligament and fibers from the biceps femoris muscle.

False

14)True or False? The normal Q-angle for males and females is the same.

False

15)True or False? The type of shoe worn has minimal, if any impact, on injuries sustained to the knee.

False

4) Which of the following muscles is part of the hamstring muscle group? a) gracilis b) sartorius c) biceps femoris d) vastus lateralis

C. Biceps femoris

6) A direct blow to the lateral aspect of the knee is a common mechanism of injury for the a) ACL b) PCL c) MCL d) LCL

C.) MCL

7) Locking is a classic sign of injury to the a) patellar bursa b) joint capsule c) medial meniscus d) ACL

C.) Medial meniscus

17)True or False? Signs and symptoms of a grade 1 quadriceps contusion include: the individual walks with a limp, mild pain, and swelling.

False

18)True or False? The function of the joint capsule in the knee is to deepen the joint and, in doing so, allow for a more stable articulation.

False

11) True or False? The lateral meniscus is a smaller and more freely moveable structure than the medial meniscus.

True

16)True or False? Injury to the prepatellar bursa will produce pain during passive knee flexion.

True

9) A common mechanism of injury for a longitudinal tear of the meniscus is a) a shearing forces from rotational motions b) a twisting motion when the foot is fixed and the knee is flexed c) deceleration combined with a cutting motion d) hyperextension

b) a twisting motion when the foot is fixed and the knee is flexed

5) Deceleration combined with a cutting motion is a common mechanism of injury for the a) ACL b) PCL c) MCL d) LCL

A. ACL

1) The menisci of the knee function to a) absorb and dissipate force b) improve the congruency of the joint c) increase knee stability d) all of the above

D. All of the above

13)True or False? The patella improves the mechanical advantage of the quadriceps muscles to produce knee extension.

True

19)True or False? The immediate management for a suspected MCL injury includes the application of ice and compression. In addition, if unable to walk without a limp, the individual should be fitted for crutches.

True
