The primary tendons in the foot include the Achilles tendon (connecting the calf to the heel bone), the tibialis posterior tendon (supporting the foot's arch), the anterior tibialis tendon (enabling the foot to lift upwards), and the peroneal tendons (providing stability along the outer ankle and foot). These strong connective tissues link muscles in the lower leg to bones in the foot, allowing for movement, stability, and balance.
Key Tendons of the Foot
➡️ Achilles Tendon:
The largest tendon in the body, it connects the calf muscles to the heel bone, facilitating activities like walking, running, and jumping.
➡️ Tibialis Posterior Tendon:
This tendon runs along the back of the leg, bends around the inner ankle, and attaches to the bones of the inner foot. It plays a crucial role in maintaining the foot's arch.
➡️ Anterior Tibialis Tendon:
Found on the front of the ankle, this tendon is responsible for lifting the foot upward (dorsiflexion).
➡️ Peroneal Tendons:
Two tendons, the peroneal longus and brevis, run along the outside of the lower leg and ankle. They connect to the outer part of the midfoot and under the foot, near the arch, providing stability, especially on uneven surfaces.
Function of Tendons
✅ Movement:
By connecting muscles to bones, tendons act as levers, pulling bones to create movement in the toes and foot when muscles contract.
✅ Stability:
Tendons, along with ligaments and bones, form a network that keeps the foot and ankle stable and balanced during movement.
Common Issues
✅ Tendinitis:
Inflammation of a tendon, often caused by overuse, can lead to pain and swelling.
✅ Tearing:
More severe injuries can involve a complete tear of a tendon, which can significantly impact mobility.
✅ Flat Feet:
Dysfunction in the tibialis posterior tendon can contribute to flat feet and pain.
