Almost all of the previous case reports have reported on rupture of the EHL tendon rather than the EHL muscle. In this report, we highlight an unusual clinical presentation of a rupture of the EHL muscle and discuss its predisposing factors. This patient was a taekwondo athlete with EHL muscle rupture secondary to repetitive overuse without any underlying systemic or local predisposing factors or direct trauma. Fifteen months after successful surgical treatment, he became fully functional again as an elite taekwondo athlete.<\/jats:p>","DOI":"10.7547\/16-012","type":"journal-article","created":{"date-parts":[[2017,10,27]],"date-time":"2017-10-27T13:19:23Z","timestamp":1509110363000},"page":"446-449","source":"Crossref","is-referenced-by-count":2,"title":["Rupture
