Insertional Achilles tendinosis is a condition where a patient complains of isolated pain at the Achilles tendon insertion site due to intratendinous degeneration. It has been suggested that this condition is associated with cavus foot deformity. However, to our knowledge, there is no study that has confirmed this observation. We carried out a cross-sectional, case-controlled study to explore the association of increased calcaneal inclination-a surgically important characteristic of cavus foot deformity-with insertional Achilles tendinosis. Patients with Achilles tendinosis and matched controls without the pathology were compared. Although a statistically significant difference was detected in calcaneal inclination angle between these 2 groups (p = .038), we felt that the difference was not clinically significant (calcaneal inclination angle = 20.9 vs. 18.9, respectively). Within the limitations of the study, we conclude that there is no clinically significant difference in calcaneal inclination between those with or without insertional Achilles tendinosis.
