The same level of quadriceps muscle mass was observed in both limbs, suggesting a lack of hypotrophy due to the injury. Although the involved limb had demonstrated lower knee extensors maximal strength, they demonstrate an equivalent early RTD when compared to the uninvolved limb. The early RTD seems to be better correlated with the patient\u2019s functionality than the later RTD and maximal strength.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Level of Evidence<\/jats:title>\n                    <jats:p>IV, case series.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1016\/j.arthro.2022.01.023","type":"journal-article","created":{"date-parts":[[2022,1,31]],"date-time":"2022-01-31T11:36:23Z","timestamp":1643628983000},"page":"2268-2277","update-policy":"https:\/\/doi.org\/10.1016\/elsevier_cm_policy","source":"Crossref","is-referenced-by-count":3,"title":["Modified Pulvertaft on Weave Technique Restores Full Active Knee Extension in Patients With Large Chronic Quadriceps Tendon Rupture: A Case Series"],"prefix":"10.1002","volume":"38","author":[{"given":"Jos\u00e9 Leonardo","family":"Rocha de Faria","sequence":"first","affiliation":[{"name":"Knee Surgery Center National Institute of Traumatology and Orthopedic Rio de Janeiro Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Conrado Torres","family":"Laett","sequence":"additional","affiliation":[{"name":"Neuromuscular Research Laboratory Research Division National Institute of Traumatology and Orthopedic Rio de Janeiro Brazil"},{"name":"Biomechanics Laboratory Physical Education and Sports School Federal University of Rio de Janeiro Rio de Janeiro Brazil"},{"name":"Research Division National Institute of Traumatology and Orthopedic Rio de Janeiro Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ubirat\u00e3 Faleiro","family":"Gavil\u00e3o","sequence":"additional","affiliation":[{"name":"Neuromuscular Research Laboratory Research Division National Institute of Traumatology and Orthopedic Rio de Janeiro Brazil"},{"name":"Biomechanics Laboratory Physical Education and Sports School Federal University of Rio de Janeiro Rio de Janeiro Brazil"},{"name":"Research Division National Institute of Traumatology and Orthopedic Rio de Janeiro Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matheus de Barros","family":"Carvalho","sequence":"additional","affiliation":[{"name":"Knee Surgery Center National Institute of Traumatology and Orthopedic Rio de Janeiro Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alan de Paula","family":"Mozella","sequence":"additional","affiliation":[{"name":"Knee Surgery Center National Institute of Traumatology and Orthopedic Rio de Janeiro Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eduardo Branco","family":"de Sousa","sequence":"additional","affiliation":[{"name":"Research Division National Institute of Traumatology and Orthopedic Rio de Janeiro Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Victor Rodrigues Amaral","family":"Cossich","sequence":"additional","affiliation":[{"name":"Neuromuscular Research Laboratory Research Division National Institute of Traumatology and Orthopedic Rio de Janeiro Brazil"},{"name":"Biomechanics Laboratory Physical Education and Sports School Federal University of Rio de Janeiro Rio de Janeiro Brazil"},{"name":"Research Division National Institute of Traumatology and Orthopedic Rio de Janeiro Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2022,1,31]]},"reference":[{"key":"e_1_2_5_2_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00167\u2010005\u20100680\u20103"},{"key":"e_1_2_5_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0736\u20104679(02)00719\u20109"},{"key":"e_1_2_5_4_2","doi-asserted-by":"publisher","DOI":"10.2106\/00004623\u2010198163060\u201000010"},{"key":"e_1_2_5_5_2","doi-asserted-by":"publisher","DOI":"10.3928\/0147\u20107447\u201019960601\u201007"},{"key":"e_1_2_5_6_2","doi-asserted-by":"publisher","DOI":"10.1177\/1457496915598761"},{"key":"e_1_2_5_7_2","doi-asserted-by":"publisher","DOI":"10.2106\/JBJS.RVW.20.00096"},{"key":"e_1_2_5_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.injury.2012.08.044"},{"key":"e_1_2_5_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.injury.2016.06.032"},{"key":"e_1_2_5_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/J.KNEE.2015.04.006"},{"key":"e_1_2_5_11_2","doi-asserted-by":"publisher","DOI":"10.2106\/JBJS.18.01098"},{"key":"e_1_2_5_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/J.RBOE.2016.03.003"},{"key":"e_1_2_5_13_2","doi-asserted-by":"publisher","DOI":"10.1016\/0002\u20109610(58)90444\u20106"},{"key":"e_1_2_5_14_2","doi-asserted-by":"publisher","DOI":"10.1001\/archsurg.1950.01250020045006"},{"key":"e_1_2_5_15_2","unstructured":"Alaia MJ Kaplan DJ Ryan WE Jr et\u00a0al.
