Achilles Tendinosis
OVERVIEW
- Similar presentation to Achilles tendonitis - big difference is tendonosis IS NOT inflammatory
- Achilles tendinosis is often asymptomatic until it presents as a rupture
- Caused by repeated micro trauma, aging, or both which leads to degeneration of the tendon
- It may elicit low-grade discomfort related to activities
- Those with tendinosis have more type III collagen fibers compared to more healthy type I fibers
- Ultrasound / MRI will reveal changes in the tendon and usually used to differentiate from achilles tendinitis
SIGNS AND SYMPTOMS
- Degenerative lesions
- Altered tendon structure (a palpable painless mass or nodule may be present 2 to 6 cm proximal to the insertion of the tendon. This can progress to gradual thickening of the entire tendon substance)
- Decreased luster
- Yellowish discoloration
- Softening
- Positive Arc Sign (nodule on the tendon will move when ankle is plantarflexed and dorsiflexed)
