The Achilles tendon is the largest tendon in the human body and can withstand forces of 1,000 pounds or more. It also is the most frequently ruptured tendon, usually as a result of a sports injury. Both professional and weekend athletes may suffer from Achilles tendonitis, a common overuse injury and inflammation of the tendon.
Peroneal Tendon Dislocation/Dysfunction
Peroneal tendons support two important foot muscles (Peroneus Brevis and Peroneus Longus) that originate on the outside of the calves. These two muscles allow you to roll to the outside of your foot while standing.
Xanthomas of the Achilles Tendon
Xanthomas are cholesterol deposits that appear in the Achilles tendon. High cholesterol levels can cause the formation of these cholesterol deposits, which appear as small lumps. Aside from treating the underlying cholesterol problem, treatment for xanthomas may require taking a biopsy of the lesion but leaving the nodules intact.
