Achilles tendinopathy is an injury to the Achilles tendon is some way. Different types of Achilles tendinopathy are:
- Achilles tendinitis: this is the acute inflammation of the Achilles tendon
- Achilles tendinosis: this is when no inflammatory cells are presen, collagen fibers in the Achilles tendon are scarred and disorganized. This is usually the cause when people have pain in their Achilles.
- Achilles tenosynovitis: inflammation of the Achilles tendon sheath. This causes fibrosis and scarring that restricts the motion of the tendon within the sheath, in other words, the tendon becomes stiff.
