Diabetes is a pandemic problem with catastrophic effects on the physical, psychological, and economic lives of patients and their families, and also places a significant burden on the healthcare system. Changes in the integumentary system lead to plantar foot ulcerations, which increase the risk of limb amputations and death. Specifically, limitation of ankle joint dorsiflexion (equinus deformity) has been implicated as a major deforming force in the development and chronicity of plantar foot ulcerations in the diabetic population. A better mechanistic understanding of the intrinsic changes in the diabetic Achilles tendon would assist in explaining and potentially preventing the development of chronic foot ulcerations due to an equinus deformity.
