  • 5 major medial ankle ligaments.
  • 3 major lateral ankle ligaments.
  • The lateral ankle ligaments are most commonly damaged.

3 Lateral Ankle Ligaments:

  1. Anterior talofibular ligament.
  2. Calcaneofibular ligament
  3. Posterior talofibular ligament.


5 (Deltoid) Medial Ankle Ligaments:

  • 1-2) Superficial & deep tibiotalar ligaments.
  • 3) Tibiocalcaneal ligament
  • 4-5) superficial & deep tibionavicular ligaments.



Lateral Ankle Ligaments:

3 Major Lateral Ankle Ligaments:


1) The Anterior Talofibular Ligament.

  • The anterior talofibular ligament is the most commonly damaged ligament in ankle sprains.
  • This ligament protects against inversion & plantarflexion.
  • If any ligaments are damaged during an inversion ankle sprain, this one is usually included!

2)The Calcaneofibular Ligament.

  • This is the second most common ligament damaged in any ankle injury.
  • This ligament protects against inversion & dorsiflexion.
  • If the calcaneofibular ligament is damaged, then the anterior talofibular ligament is also damaged.

3)The Posterior Talofibular Ligament.

  • The posterior talofibular ligament is rarely ruptured.
  • Both the calcaneofibular ligament & talofibular ligament will be damaged.





5 Major Medial Ankle Ligaments:

  • 1)Superficial tibiotalar ligament.
  • 2)Deep tibiotalar ligament.

  • 4)Superficial tibionavicular ligament.
  • 5)Deep tibionavicular ligament.



2 Major Tendons In Ankle:

There  2 major lateral ankle tendons:

  • The Peroneus Brevis Muscle Tendon.
  • The Peroneus Longus Muscle Tendon.


Strained Ankle Tendon & LigamentsThere are two major lateral ankle tendons. The peroneus brevis & the peroneus longus.


1) The Peroneus Brevis.

  • The peroneus brevis muscle tendon.
    • This muscle is involved in eversion & dorsiflexion of the foot.
    • This muscle originates at the top of the outside leg.
    • It inserts at the base of the 5th metatarsal bone.
    • It can frequently avulse the base of the 5th metatarsal.
    • This avulsion fracture is known as a Jones fracture.



2) The Peroneus Longus.

  • The peroneus longus muscle tendon.
    • This muscle is involved in eversion & plantarflexion of the foot.
    • This muscle originates at the middle outside of the leg.
    • It runs to underneath the foot and inserts to the base of the 1st metatarsal.
    • This muscle can have an accessory bone.
    • This accessory bone is called an os peroneum.
    • This accessory bone can cause irritate on the bottom of the outside of the foot.
