Achilles Paritenonitis (Tendon Sheath Inflammation) Information

Achilles Paritenonitis (Tendon Sheath Inflammation)


The Achilles tendon is the tendinous extension of three muscles in the lower leg: gastrocnemius, soleus, and plantaris, inserting into the calcaneus (heel bone). The tendon passes behind the ankle and is the thickest and strongest tendon in the body. It is about 15cm long, and begins near the middle of the leg. The tendon is surrounded by a sheath called the paratenon, which protects the tendon and helps to reduce friction.
