The participants included 23 female athletes after ACLR with STG grafts. Isometric quadriceps tests were performed using an isokinetic dynamometer. The peak torque, RTD100 (0 to 100 ms) and RTD200 (100 to 200 ms) were determined using torque-time curves. Comparisons of the LSI of torque parameters was performed by ANOVA. Univariate regression analysis was used to examine the relationship between the LSI of torque parameters and the patient-reported knee function. The LSIs of the peak torque and RTD200 were significantly lower than that of the RTD100 (p = 0.049, p = 0.039, respectively). Regression analysis showed that the LSI of the peak torque was associated with the patient-reported knee function (R2 = 0.40, p = 0.001). It would be useful to evaluate the peak torque in young female athletes under the age of 18 and at 8\u201310 months after ACLR with STG grafts.<\/jats:p>","DOI":"10.3390\/ijerph191811761","type":"journal-article","created":{"date-parts":[[2022,9,18]],"date-time":"2022-09-18T23:39:22Z","timestamp":1663544362000},"page":"11761","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Rate of Torque Development in the Quadriceps after Anterior Cruciate Ligament Reconstruction with Hamstring Tendon Autografts in Young Female Athletes"],"prefix":"10.3390","volume":"19","author":[{"given":"Makoto","family":"Suzuki","sequence":"first","affiliation":[{"name":"Faculty of Health Sciences, Hokkaido University, Sapporo 060-0812, Japan"},{"name":"Department of Rehabilitation, Hokushin Orthopaedic Hospital, Sapporo 060-0908, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0174-7416","authenticated-orcid":false,"given":"Tomoya","family":"Ishida","sequence":"additional","affiliation":[{"name":"Faculty of Health Sciences, Hokkaido University, Sapporo 060-0812, Japan"},{"name":"Department of Rehabilitation, Hokushin Orthopaedic Hospital, Sapporo 060-0908, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4663-598X","authenticated-orcid":false,"given":"Mina","family":"Samukawa","sequence":"additional","affiliation":[{"name":"Faculty of Health Sciences, Hokkaido University, Sapporo 060-0812, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hisashi","family":"Matsumoto","sequence":"additional","affiliation":[{"name":"Department of Rehabilitation, Hokushin Orthopaedic Hospital, Sapporo 060-0908, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yu","family":"Ito","sequence":"additional","affiliation":[{"name":"Department of Rehabilitation, Hokushin Orthopaedic Hospital, Sapporo 060-0908, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoshimitsu","family":"Aoki","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Hokushin Orthopaedic Hospital, Sapporo 060-0908, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Harukazu","family":"Tohyama","sequence":"additional","affiliation":[{"name":"Faculty of Health Sciences, Hokkaido University, Sapporo 060-0812, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,9,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"462","DOI":"10.1249\/MSS.0b013e318277acca","article-title":"Epidemiology of knee injuries among U.S. high school athletes, 2005\/2006-2010\/2011","volume":"45","author":"Swenson","year":"2013","journal-title":"Med.
