Q

What is the role of the patella

A

Protects anterior knee structures from trauma

Acts as a lever, increased lever arm of quadriceps - increases torque of the quads by increasing distance from axis of motion

Q

Where is the vastus lateralis

A

Most lateral

17
Q

Where is the Vastus intermedius

A

Hidden deep to the rectus femoris, between medial and lateral

18
Q

Where do all quad muscles insert

A

Tibial tuberosity

19
Q

What are the three hamstring muscles

A

Biceps femoris
Semitendinosus
Semi membranous

20
Q

Where is the bicep femoris

A

Most lateral

21
Q

Where is the semitendinosus

A

Most medial

22
Q

Where is the semi meembranosus

A

Middle

23
Q

What are the other knee flexors

A

Gastrocnemius
Popliteus
Sartorius
Gracilis

24
Q

What is it called when a muscle passes through two joints

A

Biarticular

25
Q

What happens when a muscle with multiple joint actions is articulated

A

Equal force applied at both ends of the muscle

The end with better lever arm generates more torque for the same effort

26
Q

What is the Q angle

A

The angle of the line of pull at the quadriceps

27
Q

What are the two malalignments of the knee

A

Valgus- knock knees
Varus- bow legs

28
Q

What is chondromalacia patella

A

Anterior knee pain

Mist racking of patella and damage to patella-femoral cartilage

Caused by
High Q angle
Pronation
High patella
Weak Vastus medialis
