In various Achilles tendon disorders, little attention is paid to the bone environment at the tendon insertion sites. The aim of the present study was to assess the calcaneal bone structure in Achilles tendon disorders using computed tomography (CT).


This study included 31 male patients diagnosed with various Achilles disorders, including episodes of tendon rupture (TR), conservatively treated tendinopathy (TP), and critical-stage Achilles TP treated with endoscopic surgery (TS). CT scans of both feet were conducted to assess the calcaneal bone structure in the TP and TS groups, which comprised 23 patients. Bone measurements were calculated, including the bone volume-to-total volume ratio (BV/TV), cross-sectional area (CSA), product moment of area (Ipm), and polar section modulus (Zpol).


The results demonstrated increased BV/TV, CSA, Ipm, and Zpol values in patients who underwent tendinoscopy and in patients with insertional TP.


CT images are useful for evaluating calcaneal trabecular structural alterations in patients with Achilles pathology and correlate with the TP type.
