Correlations between patient's age, gender, pre-injury physical activity and the achieved results were investigated as secondary endpoints.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>An observational retrospective study with prospective collected data was performed. Inclusion criteria were: treatment with anatomic MPFL reconstruction with gracilis tendon according to Sch\u04e7ttle\u2019s technique performed between 2011 and 2017; associated TTO as unique accessory procedure; skeletal joint maturity; a minimum follow-up of 12\u00a0months after surgery. Clinical outcomes were assessed with the Kujala, Lysholm and Tegner scores.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>Forty patients (42 knees) were included, 64% of them underwent TTO. The Kujala score significantly improved from 47.4\u2009\u00b1\u200917.6 preoperatively to 89.4\u2009\u00b1\u200913.6 postoperatively (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.01). The average Lysholm score was 45.6\u2009\u00b1\u200920.5 preoperatively: it showed a significant increase to 89.8\u2009\u00b1\u200912.8 postoperatively (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.01). Pre-injury mean Tegner was 5.9\u2009\u00b1\u20091.8, while it dropped to 3.0\u2009\u00b1\u20091.6 after injury. After surgery, Tegner resulted 4.9\u2009\u00b1\u20091.6. Forty-three percent of patients regained the pre-injury sport activity level. Redislocation rate was 2.4%.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>Anatomic MPFL reconstruction allows excellent patellar stability recovery, knee functionality improvement, return to Activities of Daily Living and a low redislocation rate. Better results were achieved in younger (under 30 years old) and higher sports activity-level subjects. The TTO association provided clinical results comparable to isolated MPFL reconstructions, suggesting that the two procedures can be safely accomplished together without affecting the positive outcomes.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Level of evidence<\/jats:title>\n                <jats:p>Level IV.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1007\/s12306-021-00721-y","type":"journal-article","created":{"date-parts":[[2021,7,10]],"date-time":"2021-07-10T18:02:46Z","timestamp":1625940166000},"page":"441-448","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Anatomic medial patellofemoral ligament (MPFL) reconstruction with and without tibial tuberosity osteotomy for objective patellar instability"],"prefix":"10.1007","volume":"106","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0239-2576","authenticated-orcid":false,"given":"A.","family":"Pautasso","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"L.","family":"Sabatini","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"Capella","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"F.","family":"Saccia","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"L.","family":"Rissolio","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"G.","family":"Boasso","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"F.","family":"Atzori","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.","family":"Mass\u00e8","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2021,7,10]]},"reference":[{"key":"721_CR1","first-page":"381","volume":"55","author":"PP Casteleyn","year":"1989","unstructured":"Casteleyn PP, Handelberg F (1989) Arthroscopy in the diagnosis of occult dislocation of the patella.
