Kinesiology Test 2 Study Guide (Calf/Knee/Thigh)

What are Valgus Forces and what do they do?

A lateral blow to the knee joint which may cause injuries such as a torn tibial collateral ligament, a torn medial meniscus, or a torn anterior cruciate ligament

Strength Ratio of Quads and Hamstrings

3:2

Primary Function of Quads

Extend the knee

Primary Function of Hamstrings

Flex the knee

Importance of Q-Angle

Help access knee alignment and patellar tracking. Men are 15 Degree or less and Women are 20 degree or less. Central line pulls for the quads. You can measure the ASIS > tibial tuberosity > Pubis with the angle between these two lines is your Q-Angel.

What produces Dynamic Stability of the Knee?

The Contraction of the hamstrings and quadriceps

Pes Anserinus

Distally Conjoined Tendon of Gracilis, Sartorius, and Semitendinosus

Pes anserinus assists with knee flexion ______

Using the posteromedial line of pull

Pes Anserinus does what rotation?

Internal Rotation of the hip

Tight Pes Anserinus causes _____

Reduced extension of the leg and lack of internal rotation of the hip

Pes Anserinus can mimic MCL pain during inflammation of the bursa because ________

The Pes Anserinus attaches to a similar area to the MCL and cover the Pes Anserinus Bursa

LCL

lateral collateral ligament/stabilizes in adduction

MCL

Medial collateral ligament/stabilizes in abduction

ACL

anterior cruciate ligament

PCL

posterior collateral ligament

knee, mobile or stable?

stable

cause of injury to the knee

mainly caused by dysfunction in the hip or ankle

Flexor hallucis longus

It starts on the lower two-thirds of the back of the fibula and the adjacent interosseous membrane. It attaches to the base of the distal phalanx of the big toe. It bends the big toe, helps with push-off, and assists ankle plantarflexion.
