The purpose of this study was to compare the bilateral thickness of each quadricep component before and after ACLR. Materials and Methods: Cross-sectional study design. In 14 patients who underwent ACLR, bilateral quadricep muscle thicknesses were measured using a portable ultrasound device, 1 h before and 48\u201372 h after ACLR. Two-way analysis of variance (ANOVA) was used to compare muscle thickness pre- and post-ACLR between the limbs. Results: The primary finding was that the vastus intermedius (VI) muscle was significantly smaller in the reconstructed limb after ACLR compared to that in the healthy limb (Reconstructed limb; RCL = Pre-operated (PRE): 19.89 \u00b1 6.91 mm, Post-operated(POST): 16.04 \u00b1 6.13 mm, Healthy limb; HL = PRE: 22.88 \u00b1 6.07, POST: 20.90 \u00b1 5.78 mm, F = 9.325, p = 0.009, \u03b72p = 0.418). Conclusions: The results represent a selective surgical influence on the quadricep muscle thickness. These findings highlight the need of advanced strengthening exercises in order to restore VI thickness after ACLR.<\/jats:p>","DOI":"10.3390\/medicina56070335","type":"journal-article","created":{"date-parts":[[2020,7,6]],"date-time":"2020-07-06T03:19:27Z","timestamp":1594005567000},"page":"335","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Bilateral Comparisons of Quadriceps Thickness after Anterior Cruciate Ligament Reconstruction"],"prefix":"10.3390","volume":"56","author":[{"given":"Joo-Hyun","family":"Lee","sequence":"first","affiliation":[{"name":"Department of Kinesiology, Inha University, Incheon 22212, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Soul","family":"Cheon","sequence":"additional","affiliation":[{"name":"Department of Kinesiology, Inha University, Incheon 22212, Korea"},{"name":"Institute of Sports and Arts Convergence (ISAC), Inha University, Incheon 22212, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hyung-Pil","family":"Jun","sequence":"additional","affiliation":[{"name":"Department of Physical Education, Dong-A University, Busan 49236, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yu-Lun","family":"Huang","sequence":"additional","affiliation":[{"name":"Department of Kinesiology, University of Wisconsin-Eau Claire, Eau Clair, WI 54702, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eunwook","family":"Chang","sequence":"additional","affiliation":[{"name":"Department of Kinesiology, Inha University, Incheon 22212, Korea"},{"name":"Institute of Sports and Arts Convergence (ISAC), Inha University, Incheon 22212, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,7,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"117","DOI":"10.1055\/s-0035-1558855","article-title":"Motion analysis and the anterior cruciate ligament: Classification of injury risk","volume":"29","author":"Bates","year":"2016","journal-title":"J.
