The peroneus muscles are a group of muscles located on the side of the leg. While the muscle group is normally composed of three muscles: peroneus longus, brevis and tertius. The peroneus muscles originates from lower two-third of the lateral side of the fibula and attaches to the metatarsals bones in the foot.

The peroneus longus and brevis are much more prone to injury compared to peroneus tertius. Peroneus longus, brevis and tertius evert the foot (sole of foot facing inwards); the peroneus longus and brevis plantarflex the foot (stand on your toes).  The peroneus tertius dorsiflexes it (walking on the heels).

The peroneal muscles are responsible for rolling the foot outwards and plantar flexing the foot.  These two relativity small muscles are important stabilizers for the ankle. The peroneal muscle tendons run around the outside of the ankle with a small broad band of tough tissue holding the tendons in place.

When the tendons are repetitively overloaded by certain activities, they become inflamed or stretched.  In some cases, the tough tissue holding the tendons in place can become inflamed and stop free moment of the tendons.

Peroneus Tendonitis Can Come From:

  • Repetitive motion and high forces create excess tension to the muscles. Mostly related to sports: running, jumping.
  • Poor footwear.
  • Flat feet.
  • Heel turned inwards – forcing stretching of the peroneus muscles.
  • Ankle sprain.
  • Age.

Symptoms of Peroneus Tendonitis:

  • Pain outside of the ankle.
  • Weakness or instability of the ankle.
  • Pain gradually increasing overtime.
  • Worsens with activity. Better with rest.  Though without treatment, pain will occur during rest.
  • Swelling around the tendons on the outside of the ankle.
  • If the tendons are inflamed and not treated, can result in microtears and/or a rupture.

I approach treating your knee pain to your presentation, which involves:

  • Analyzing your posture – What’s going on with the alignment of your hip, knee and ankle? How is your posture could be causing the peroneus tendons to be inflamed?
  • Discussing potential lifestyle dynamics impacting the effecting your pain.
  • Understanding how other factors playing into your pain.
  • Muscle testing the muscles for weakness and pain.
  • Targeting effected muscles, releasing motor points, trigger points and relaxing the fascia.
  • Providing exercises to continue treatment success between acupuncture treatments.
