The patient experienced intermittent pain during walking, particularly after prolonged periods of sitting, and exhibited positive findings on meniscus tests. However, he was able to participate in sports activities without pain. Magnetic resonance imaging (MRI) revealed a\u00a0partial tear of the medial gastrocnemius head, confirming the diagnosis. Conservative treatment, including rest, physical therapy, and a\u00a0gradual return to sports activities, led to significant symptom improvement. This case highlights the importance of considering rare injuries, such as isolated tears of the medial gastrocnemius head, in patients with persistent knee pain and meniscal symptoms, even in the absence of traumatic events. Previous reports on this specific injury are sparse, indicating its rarity and underscoring the need for further understanding and documentation.<\/jats:p>","DOI":"10.1007\/s00113-025-01534-5","type":"journal-article","created":{"date-parts":[[2025,2,6]],"date-time":"2025-02-06T08:15:23Z","timestamp":1738829723000},"page":"319-323","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Partial tear of the medial gastrocnemius head","Teilruptur des medialen Kopfs des M.\u00a0gastrocnemius"],"prefix":"10.1007","volume":"128","author":[{"given":"Daniel P.","family":"Berthold","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fabian","family":"Traub","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fabian","family":"Gilbert","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wolfgang","family":"B\u00f6cker","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Boris","family":"Holzapfel","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Markus","family":"Bormann","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2025,2,6]]},"reference":[{"key":"1534_CR1","doi-asserted-by":"publisher","first-page":"112","DOI":"10.1148\/radiol.2241011067","volume":"224","author":"GJ Delgado","year":"2002","unstructured":"Delgado\u00a0GJ, Chung\u00a0CB, Lektrakul\u00a0N, Azocar\u00a0P, Botte\u00a0MJ, Coria\u00a0D, Bosch\u00a0E, Resnick\u00a0D (2002) Tennis leg: clinical US study of 141 patients and anatomic investigation of four cadavers with MR imaging and US.
