One joint muscles that act on the knee
- vastus medialis
- popliteus
- short head of the biceps
Two joint muscles that act on the knee
- rectus femoris
- iliotibial tract of tensor fascia latae
- gracilis
- long head of the biceps femurs
- semitendinosus
- semimembranosus
Which muscle is most important for terminal extension of the knee?
vastus medals (not entirely true, they’re all important)
With an incomplete lesion of the medical division of the sciatic nerve (i.e. tibial nerve), which maneuver will bring out the gait deviation to be expected?
Walking down a ramp
Forces for full knee extension
There is a 60% increase in the force needed to go from 15 degrees to full extension.
Q angle
Formed by drawing a line from the ASIS through the center of the patella and drawing another line from the center of the patella to the tibial tuberosity.
