After unsuccessful conservative therapy, the differential diagnosis of myositis ossificans was suspected and confirmed on radiographic examination. MRI revealed significant edema encompassing a substantial portion of the vastus intermedius muscle. <jats:italic><jats:bold>Management and outcomes<\/jats:bold>:<\/jats:italic> Surgical treatment was considered for the right thigh mass, being symptomatic 1\u00a0month after the onset and refractory to conservative treatment and rehabilitation program. At 2\u00a0months postsurgery, the patient was asymptomatic and had completed a rehabilitation program. <jats:italic><jats:bold>Conclusion<\/jats:bold>:<\/jats:italic> Early surgical treatment followed-up with a rehabilitation program results with a complete recovery of muscle strength and range of motion. At 3\u00a0months postinitial injury, the patient was considered fully recovered and had returned to the match without reporting pain or other symptoms.<\/jats:p>","DOI":"10.1123\/jsr.2024-0114","type":"journal-article","created":{"date-parts":[[2025,1,18]],"date-time":"2025-01-18T04:24:45Z","timestamp":1737174285000},"page":"667-671","source":"Crossref","is-referenced-by-count":2,"title":["Early Surgical Treatment of Posttraumatic Myositis Ossificans of the Vastus Intermedius Muscle"],"prefix":"10.1123","volume":"34","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-1950-070X","authenticated-orcid":true,"given":"Pave","family":"Kalebi\u0107","sequence":"first","affiliation":[{"name":"Polyclinic for Orthopedics, Physical Medicine and Physical Therapy \u201cScipion\u201d, Rijeka, Croatia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2524-1324","authenticated-orcid":true,"given":"Silvije","family":"\u0160egulja","sequence":"additional","affiliation":[{"name":"Department of Clinical Sciences, Faculty of Health Studies, University of Rijeka, Rijeka, Croatia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8787-9550","authenticated-orcid":true,"given":"Bojan","family":"Mileti\u0107","sequence":"additional","affiliation":[{"name":"Department of Clinical Sciences, Faculty of Health Studies, University of Rijeka, Rijeka, Croatia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2508-707X","authenticated-orcid":true,"given":"Hrvoje","family":"Vlahovi\u0107","sequence":"additional","affiliation":[{"name":"Department of Physiotherapy, Faculty of Health Studies, University of Rijeka, Rijeka, Croatia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7252-2340","authenticated-orcid":true,"given":"Gordana","family":"Star\u010devi\u0107-Klasan","sequence":"additional","affiliation":[{"name":"Department of Basic Medical Sciences, Faculty of Health Studies, University of Rijeka, Rijeka, Croatia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"100","reference":[{"key":"r1","series-title":"EFORT Open Rev","doi-asserted-by":"publisher","first-page":"572","DOI":"10.1302\/2058-5241.6.210002","article-title":"Post-traumatic myositis ossificans: a benign lesion that simulates malignant bone and soft tissue tumours","volume":"6","author":"Savvidou O","year":"2021","unstructured":"Savvidou O, Papakonstantinou O, Lakiotaki E, Melissaridou D, Korkolopoulou P, Papagelopoulos PJ.
