2
Q

What is the angle that is formed by a line drawn from the ASIS to the central patella and a second line drawn from the central patella to a tibial tubercle?

A

Q-Angle

3
Q

The Q-angle is increased by…..

A
  • genu algum
  • increased femoral ante version
  • external tibial torsion

  • tight lateral retinaculum
4
Q

What nerve helps in extension?

A

Femoral Nerve

5
Q

What nerve helps in flexion?

A

Sciatic Nerve

6
Q

What provides sagittal plane stability?

A

cruciate ligament

7
Q

What ligament keeps the femur from being displaced posteriorly on the tibia, and prevents the tibia from being anteriorly displaced relative to the femur?

A

ACL (anterior cruciate ligament)

8
Q

What ligament runs from the posterior tibia to the anterior femur and keeps the femur from being displaced anteriorly on the tibia? (is less likely to be injured)

A

PCL (posterior cruciate ligament)

9
Q

MCL & LCL

10
Q

A

MCL

11
Q

What provides stability from a blow to the medial knee?

A

LCL

12
Q

What is designed to absorb shock?

A

meniscus

13
Q

What is the area behind the knee that contains blood vessels and nerves?

Q

PATHOLOGY : bow legs, knees apart but ankles touch

A

Genu Varum

16
Q

PATHOLOGY : knee positioned in hyperextension during stance

A

Genu Recurvatum

17
Q

PATHOLOGY : softening and degeneration of the cartilage on posterior aspect of the patella causing anterior knee pain

A

Chondromalacia Patella

18
Q

PATHOLOGY : occurs with constant pressure between the skin and the patella

A

Prepatellar Bursitis

19
Q

PATHOLOGY : causes diffuse anterior knee pain

A

Patellofemoral Pain Syndrome

20

23
Q

What are the motions of the ankle?

A

1) plantarflexion - foot moves downward
2) dorsiflexion - foot moves upward toward dorsal surface
3) inversion - bottom of foot turns inward
4) eversion - bottom of foot turns outward
