This addresses soft tissue injury but does not address underlying anatomic factors, including trochlear dysplasia, that are commonly present and increase risk of dislocation. Quantification of the stability offered by other surgical interventions, namely, medializing tibial tubercle osteotomy (mTTO) and trochleoplasty, with and without MPFLR, may provide insight for surgical choices in patients with trochlear dysplasia. We developed subject\u2010specific finite element models based on magnetic resonance scans from a cohort of 20 patients with trochlear dysplasia and recurrent patellar dislocation. The objectives of this study were (1) to compare patella stability after mTTO and trochleoplasty procedures; (2) to evaluate whether it is necessary to perform an MPFLR in combination with the mTTO or trocheoplasty procedure; and (3) to quantify the robustness of patellar stability to variability in knee kinematics. Trochleoplasty performed better than mTTO at stabilizing the patella between 5\u00b0 and 30\u00b0 flexion. For both mTTO and trochleoplasty procedures, it was beneficial to also perform MPFLR\u2014inclusion of MPFLR halved the magnitude of patellar laxity predicted in the simulations. Simulations that did not include any medial patellofemoral ligament restraint\u00a0were also more sensitive to variation in tibiofemoral internal\u2013external kinematics.<\/jats:p>","DOI":"10.1002\/jor.25519","type":"journal-article","created":{"date-parts":[[2023,1,24]],"date-time":"2023-01-24T09:38:39Z","timestamp":1674553119000},"page":"1687-1696","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Computational comparison of medializing tibial tubercle osteotomy and trochleoplasty in patients with trochlear dysplasia"],"prefix":"10.1002","volume":"41","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8200-9353","authenticated-orcid":false,"given":"Clare K.","family":"Fitzpatrick","sequence":"first","affiliation":[{"name":"Mechanical and Biomedical Engineering Boise State University Boise Idaho USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robert N.","family":"Steensen","sequence":"additional","affiliation":[{"name":"Mount Carmel Health System  Columbus Ohio USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Oliver","family":"Alvarez","sequence":"additional","affiliation":[{"name":"Mechanical and Biomedical Engineering Boise State University Boise Idaho USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amy E.","family":"Holcomb","sequence":"additional","affiliation":[{"name":"Mechanical and Biomedical Engineering Boise State University Boise Idaho USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3831-8623","authenticated-orcid":false,"given":"Paul J.","family":"Rullkoetter","sequence":"additional","affiliation":[{"name":"Center for Orthopaedic Biomechanics University of Denver  Denver Colorado USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,1,30]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-198668050-00025"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1177\/2325967118766275"},{"key":"e_1_2_7_4_1","first-page":"1037\u20101043","article-title":"High rate of recurrent patellar dislocation in skeletally immature patients: a long\u2010term population\u2010based study","volume":"26","author":"Sanders TL","year":"2018","journal-title":"Knee Surg, Sports Traumatol, Arthrosc"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1177\/0363546517704178"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.arthro.2022.01.044"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1186\/s13018-021-02513-3"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1177\/0363546510373887"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1177\/0363546514563904"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1177\/03635465980260012701"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-199305000-00007"},{"key":"e_1_2_7_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jor.2021.11.002"},{"key":"e_1_2_7_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.otsr.2021.103160"},{"key":"e_1_2_7_14_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00264-012-1746-8"},{"key":"e_1_2_7_15_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00167-016-4365-x"},{"key":"e_1_2_7_16_1","doi-asserted-by":"publisher","DOI":"10.1177\/0363546513478579"},{"key":"e_1_2_7_17_1","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.90B7.20447"},{"key":"e_1_2_7_18_1","doi-asserted-by":"publisher","DOI":"10.1177\/03635465211041087"},{"key":"e_1_2_7_19_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.clinbiomech.2020.105216"},{"key":"e_1_2_7_20_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.knee.2017.01.011"},{"key":"e_1_2_7_21_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.arthro.2021.08.008"},{"key":"e_1_2_7_22_1","doi-asserted-by":"publisher","DOI":"10.1097\/JSA.0000000000000152"},{"key":"e_1_2_7_23_1","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.102B1.BJJ-2019-0366.R3"},{"key":"e_1_2_7_24_1","doi-asserted-by":"publisher","DOI":"10.1002\/jor.23041"},{"key":"e_1_2_7_25_1","doi-asserted-by":"publisher","DOI":"10.1002\/jor.24526"},{"key":"e_1_2_7_26_1","doi-asserted-by":"publisher","DOI":"10.1002\/jor.1100160123"},{"key":"e_1_2_7_27_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jbiomech.2011.05.006"},{"key":"e_1_2_7_28_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jbiomech.2009.06.028"},{"key":"e_1_2_7_29_1","doi-asserted-by":"publisher","DOI":"10.1115\/1.4002854"},{"key":"e_1_2_7_30_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jbiomech.2022.111118"},{"key":"e_1_2_7_31_1","unstructured":"AtkinsonP AtkinsonT HuangC DoaneR.A comparison of the mechanical and dimensional properties of the human medial and lateral patellofemoral ligaments.Proceedings of the 46th Annual Meeting of the Orthopaedic Research Society.
