The mechanism of injury is often related to sports (i.e football and basketball). Fifteen patients who had this kind of fracture underwent surgical Open Reduction and Internal Fixation (ORIF) with two or three cannulated screws and tendon stripping. In this kind of injury and treatment, one of the most important concerns is the recovery of the extensor apparatus strength of the lower limb. Materials and Methods: We followed up the patients for 12 months, performing biomechanical tests and a kinetic analysis to evaluate the activation of the leg muscles such as rectus femoris, vastus medialis, vastus lateralis, and semitendinosus muscle fibers and compared them with the contralateral healthy limb. Results: The results showed that there was an almost complete recovery of muscle strength activation without any statistically significant differences compared to the healthy limb. Conclusions: This surgical treatment appears to be safe and effective in the treatment of tibial apophysis fractures in young athletes, since this type of surgical treatment does not compromise the recovery of the extensor apparatus strength and\/or return to sport of the lower limb in case of tibial apophysis fractures in young athletes.<\/jats:p>","DOI":"10.3390\/children12050533","type":"journal-article","created":{"date-parts":[[2025,4,22]],"date-time":"2025-04-22T20:24:52Z","timestamp":1745353492000},"page":"533","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Tibial Tubercle Avulsion Fracture in Young Athletes Surgically Treated: Mid-Long Term Result and Comparison"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4215-7615","authenticated-orcid":false,"given":"Lorenzo","family":"Moretti","sequence":"first","affiliation":[{"name":"Orthopaedic & Trauma Unit, Department of Basic Medical Sciences, Neuroscience and Sense Organs, School of Medicine, University of Bari Aldo Moro, AOU Consorziale Policlinico, 70124 Bari, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carlo","family":"Amati","sequence":"additional","affiliation":[{"name":"Orthopaedic & Trauma Unit, Giovanni Paolo XXIII Pediatric Hospital, University of Bari \u201cAldo Moro\u201d Via Giovanni Amendola, 207, 70126 Bari, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-0326-5149","authenticated-orcid":false,"given":"Alessandro","family":"Geronimo","sequence":"additional","affiliation":[{"name":"Orthopaedic & Trauma Unit, Department of Basic Medical Sciences, Neuroscience and Sense Organs, School of Medicine, University of Bari Aldo Moro, AOU Consorziale Policlinico, 70124 Bari, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrea Michele","family":"Abbaticchio","sequence":"additional","affiliation":[{"name":"Orthopaedic & Trauma Unit, Department of Basic Medical Sciences, Neuroscience and Sense Organs, School of Medicine, University of Bari Aldo Moro, AOU Consorziale Policlinico, 70124 Bari, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria Paola","family":"Miolla","sequence":"additional","affiliation":[{"name":"Orthopaedic & Trauma Unit, Giovanni Paolo XXIII Pediatric Hospital, University of Bari \u201cAldo Moro\u201d Via Giovanni Amendola, 207, 70126 Bari, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniela","family":"Dibello","sequence":"additional","affiliation":[{"name":"Orthopaedic & Trauma Unit, Giovanni Paolo XXIII Pediatric Hospital, University of Bari \u201cAldo Moro\u201d Via Giovanni Amendola, 207, 70126 Bari, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giuseppe","family":"Solarino","sequence":"additional","affiliation":[{"name":"Orthopaedic & Trauma Unit, Department of Basic Medical Sciences, Neuroscience and Sense Organs, School of Medicine, University of Bari Aldo Moro, AOU Consorziale Policlinico, 70124 Bari, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,4,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"469","DOI":"10.1007\/s11832-008-0131-z","article-title":"Tibial tuberosity fractures in adolescents","volume":"2","author":"Frey","year":"2008","journal-title":"J.
