Although its precise etiology remains uncertain, mechanical stress and repetitive traction forces are frequently implicated. Haglund\u2019s deformity, defined as a bony enlargement on the posterosuperior calcaneus, results in retrocalcaneal impingement of the Achilles tendon. While both conditions involve stress-related alterations of the calcaneus, their potential association has not been clearly established. This study aimed to evaluate the relationship between PCS and Haglund\u2019s deformity by determining the incidence of Haglund\u2019s deformity in symptomatic PCS patients and investigating associated factors.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      In this retrospective case\u2013control study, 377 patients aged \u226518\u00a0years who underwent weight-bearing lateral foot radiographs between March 2023 and March 2024 were included.
