Thyroid Achilles tendinopathy.

Achilles tendinopathy (AT) is characteristic of the multifactorial condition and protracted duration. Besides the extrinsic factors like mechanical overload or medications usage, many comorbidities including autoimmune inflammation, metabolic maladaptation and endocrinopathies can contribute to the occurrence of AT as the intrinsic factors. We observe the role of intrinsic thyroid factors and propose the notion of "thyroid Achilles tendinopathy." We think that AT can be the sentinel complaint in the patients with asymptomatic hypothyroidism or Hashimoto's thyroiditis. AT probably is not only an orthopedic issue especially in the sedentary middle-aged women who should be reminded of the systemic dysmetabolic factors like thyroid dysfunction.
