Anatomy
Tibialis Anterior and Peroneal Muscles
At the front and side of the lower leg, tibialis anterior and the peroneals control the ankle. They are often involved after a sprain or a sudden increase in running.
- Tibialis anterior
- Fibularis longus
Where is it?
Tibialis anterior runs down the front of the shin and ends on the inner edge of the foot. Fibularis (peroneus) longus and brevis run along the outside of the leg; their tendons pass behind the outer ankle bone into the foot.
What does it do?
Tibialis anterior lifts the foot so it clears the ground when walking and controls heel landing. The peroneals turn the foot outward, stabilise the ankle and support the arch.
Common problems
Each problem has its own detailed page: symptoms, causes, treatment and when to seek care.
How we can help
When to seek care
Book an appointment if leg or ankle pain returns with activity or your ankle keeps rolling. Precise bone pain, inability to bear weight, deformity, a sudden foot drop or a very tight, painful lower leg needs urgent medical assessment.
