We report a 63-year-old woman who developed persistent proximal posterior thigh pain after sprinting, followed by progressive sitting pain despite conservative treatment. High-resolution musculoskeletal ultrasonography revealed focal structural abnormalities of the ischiocondylar portion of the adductor magnus at the tendon insertion and musculotendinous junction that were consistent with a partial tear, accompanied by surrounding inflammatory changes and ischial bursal fluid. The lesion was identified beginning with the short-axis view of the ischial tuberosity, followed by an oblique long-axis view of the ischiocondylar tendon. Conservative rehabilitation, activity modification, and low-level laser therapy resulted in complete symptom resolution without recurrence. This report emphasizes that injury of the ischiocondylar portion of the adductor magnus represents an uncommon differential consideration in patients presenting with proximal posterior thigh or ischial pain. A systematic ultrasound examination with appropriate transducer orientation facilitates accurate diagnosis and appropriate management.<\/jats:p>","DOI":"10.3390\/diagnostics16162583","type":"journal-article","created":{"date-parts":[[2026,8,17]],"date-time":"2026-08-17T10:04:36Z","timestamp":1786961076000},"page":"2583","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Ultrasonographic Diagnosis of an Ischiocondylar Adductor Magnus Partial Tear: An Uncommon Cause of Ischial Pain"],"prefix":"10.3390","volume":"16","author":[{"given":"Chia-Yen","family":"Hsu","sequence":"first","affiliation":[{"name":"Department of Physical Medicine and Rehabilitation, National Taiwan University Hospital, Taipei 108207, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7511-9629","authenticated-orcid":false,"given":"Wei-Ting","family":"Wu","sequence":"additional","affiliation":[{"name":"Department of Physical Medicine and Rehabilitation and Community and Geriatric Research Center, National Taiwan University Hospital, Bei-Hu Branch, Taipei 108206, Taiwan"},{"name":"Department of Physical Medicine and Rehabilitation, National Taiwan University College of Medicine, Taipei 100233, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu-Chun","family":"Hsu","sequence":"additional","affiliation":[{"name":"Department of Physical Medicine and Rehabilitation and Community and Geriatric Research Center, National Taiwan University Hospital, Bei-Hu Branch, Taipei 108206, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7558-5651","authenticated-orcid":false,"given":"Ke-Vin","family":"Chang","sequence":"additional","affiliation":[{"name":"Department of Physical Medicine and Rehabilitation and Community and Geriatric Research Center, National Taiwan University Hospital, Bei-Hu Branch, Taipei 108206, Taiwan"},{"name":"Department of Physical Medicine and Rehabilitation, National Taiwan University College of Medicine, Taipei 100233, Taiwan"},{"name":"Center for Regional Anesthesia and Pain Medicine, Wang-Fang Hospital, Taipei Medical University, Taipei 110301, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Levent","family":"\u00d6z\u00e7akar","sequence":"additional","affiliation":[{"name":"Department of Physical and Rehabilitation Medicine, Hacettepe University Medical School, Ankara 06100, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,8,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2115","DOI":"10.1007\/s00167-013-2744-0","article-title":"The hamstring muscle complex","volume":"23","author":"Wieldraaijer","year":"2015","journal-title":"Knee Surg.
