Demographic and surgical data were retrospectively queried for patients \u226418 years of age with primary ACL reconstruction performed at a single academic center between 2011 and 2016 and minimum of 2-year clinical surveillance. Patellar height indices, including Caton\u2013Deschamps index (CDI) and Insall\u2013Salvati index (ISI), were retrospectively calculated from preoperative imaging to assess the presence of patella alta. Failure was defined as (1) ACL graft rerupture, (2) Lachman's grade 2\u2009+\u2009, (3) presence of pivot shift, and (4) side-to-side difference of 3\u2009mm on KT-1000 arthrometer. A total of 184 patients (84 females and 100 males) and 192 knees were identified, with an average age of 16.2\u2009\u00b1\u20091.8 years. Of these, 30 (15.63%) experienced ACL failure. Male sex was the only significant risk factor for rerupture (p\u2009=\u20090.026). The mean CDI was 1.06\u2009\u00b1\u20090.17 and mean ISI was 1.04\u2009\u00b1\u20090.15. Of the 49 knees that met criteria for patella alta on radiographic evaluation, rerupture occurred in seven (14.29%). Patella alta was not a significant risk factor for ACL failure among adolescent patients (p\u2009=\u20090.359 and 0.277). Only male sex was associated with increased rates of ACL failure. Age, graft selection technique, fixation construct, and presence of patella alta were not risk factors for reinjury. This study is a therapeutic case series and reflects level of evidence IV.<\/jats:p>","DOI":"10.1055\/s-0042-1749608","type":"journal-article","created":{"date-parts":[[2022,7,7]],"date-time":"2022-07-07T23:55:52Z","timestamp":1657238152000},"page":"1150-1156","source":"Crossref","is-referenced-by-count":1,"title":["Rates of Anterior Cruciate Ligament Rerupture in Adolescent Patients with and without Patella Alta"],"prefix":"10.1055","volume":"36","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4430-7066","authenticated-orcid":false,"given":"Danielle","family":"Rider","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Wake Forest School of Medicine Ringgold Standard Institution, Bowman Gray Center for Medical Education, Winston-Salem, North Carolina"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anirudh K.","family":"Gowd","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Wake Forest School of Medicine Ringgold Standard Institution, Winston-Salem, North Carolina"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"LeeAnne F.","family":"Torres","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Wake Forest School of Medicine Ringgold Standard Institution, Winston-Salem, North Carolina"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lisa W.","family":"Kaplin","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Orthopaedic Surgery and Rehabilitation Associates, Rockledge, Pennsylvania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Brian R.","family":"Waterman","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, William Beaumont Army Medical Center, El Paso, Texas"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2022,7,7]]},"reference":[{"issue":"01","key":"ref1","doi-asserted-by":"crossref","first-page":"2325967114563664","DOI":"10.1177\/2325967114563664","article-title":"Trends in anterior cruciate ligament reconstruction in the United States","volume":"3","author":"L T Buller","year":"2014","journal-title":"Orthop J Sports Med"},{"issue":"03","key":"ref2","doi-asserted-by":"crossref","first-page":"675","DOI":"10.1177\/0363546513518412","article-title":"20 years of pediatric anterior cruciate ligament reconstruction in New York State","volume":"42","author":"E R Dodwell","year":"2014","journal-title":"Am J Sports Med"},{"issue":"04","key":"ref3","doi-asserted-by":"crossref","first-page":"801","DOI":"10.1016\/j.csm.2011.08.001","article-title":"Anterior cruciate ligament reconstruction in the young athlete: a treatment algorithm for the skeletally immature","volume":"30","author":"M D Milewski","year":"2011","journal-title":"Clin Sports Med"},{"issue":"10","key":"ref4","doi-asserted-by":"crossref","first-page":"2363","DOI":"10.1177\/0363546514542796","article-title":"Incidence and trends of anterior cruciate ligament reconstruction in the United States","volume":"42","author":"N A Mall","year":"2014","journal-title":"Am J Sports Med"},{"issue":"01","key":"ref5","doi-asserted-by":"crossref","first-page":"38","DOI":"10.1302\/0301-620X.84B1.0840038","article-title":"The natural history and treatment of rupture of the anterior cruciate ligament in children and adolescents.
