extends hip
Tibialis Anterior (19)

of tibia, interosseous membrane
I: Medial inferior surface of the 1st cuneiform
and base of 1st metatarsal
A:Dorsiflexes ankle, inverts foot, supports
longitudinal arch
Fibularis Longus (22)
O: Head, superior 2/3 of lateral fibula
I: Plantar surface of base of 1st metatarsal and 1st
cuneiform
A Everts foot, weakly plantar flexes ankle,
supports transverse
Fibularis Brevis (23)
O: Lateral inferior 2/3 of fibula
I: Dorsal surface of tuberosity of 5th metatarsal
metatarsal
A: Everts foot, weakly plantar flexes ankle,
supports transverse arch
Gastrocnemuis (24a and
24b)
O: Lateral head: Lateral condyle of
femur.
Medial Head: Superior to medial
condyle of femur.
I: Calcaneus via calcaneal tendon
A:Plantarflexes ankle, flexes leg at
knee
Soleus
O: Posterior head of fibula, posterior
medial tibia
I: Calcaneus via calcaneal tendon
A: Plantarflexes ankle

Torn ACL
Also called: Anterior cruciate ligament injury
Athletes who participate in high demand
sports like soccer, football, and basketball are
more likely to get injured.
The knee joint is located where the end of the
thigh bone (femur) meets the top of the shin
bone (tibia).
This tear is more common in women responds
differently to certain maneuvers such as
jumps, sudden stops, pivoting and cutting.
Recovering time
may take six to nine
months to return to
full activity
ACL reconstruction
surgery right away
after tear
Physical therapy
and/or occupational
therapy following
surgery is needed.
Torn ACL
In Conclusion
o
Remember the mnemonic The Circus Needs More Interesting Little Clowns for
the foot bones
o
Torn ACL happen most often in women, however they can happen in men as
well
o
For the patella, whichever way it leans when put down on a flat surface with the
point pointed upwards is the side it belongs to
o
o
Calcaneal tendon and Achilles tendon are the same thing
Great saphenous vein is the longest vein in the body, running all the length of leg
