A total of 35 children without underlying diseases were enrolled containing 64 physes (44 distal femoral (DT), 20 proximal tibial (PT)). Anatomic tibiofemoral angle (aTFA) and the mechanical axis deviation (MAD) were taken from teleroentgenograms before PETS surgery and screw removal. The correction rates of the valgus and varus deformities for patients treated with PETS were 1.146\u00b0\/month and 0.639\u00b0\/month using aTFA while using MAD showed rates of 4.884%\/month and 3.094%\/month. After aTFA (p &lt; 0.001) and MAD (p &lt; 0.001) analyses, the correction rate of DF was significantly faster than that of PT. Under multivariable analysis, the aTFA correction rate was significantly faster in younger patients (p &lt; 0.001), in males (p &lt; 0.001), in patients with lower weights (p &lt; 0.001), and in the group that was screwed at DF (p &lt; 0.001). Meanwhile, the MAD correction rate was significantly faster in patients with lower heights (p = 0.003). PETS is an effective treatment method for valgus and varus deformities in growing children and clinical characters should be considered to estimate the correction rate.<\/jats:p>","DOI":"10.3390\/jcm9124093","type":"journal-article","created":{"date-parts":[[2020,12,21]],"date-time":"2020-12-21T04:12:01Z","timestamp":1608523921000},"page":"4093","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Affecting Factors and Correction Ratio in Genu Valgum or Varum Treated with Percutaneous Epiphysiodesis Using Transphyseal Screws"],"prefix":"10.3390","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2733-6992","authenticated-orcid":false,"given":"Si-Wook","family":"Lee","sequence":"first","affiliation":[{"name":"Department of Orthopedic Surgery, Keimyung University Dongsan Hospital, Keimyung University School of Medicine, 1035 Dalgubeol-daero, Dalseo-gu, Daegu 42601, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4811-574X","authenticated-orcid":false,"given":"Kyung-Jae","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Keimyung University Dongsan Hospital, Keimyung University School of Medicine, 1035 Dalgubeol-daero, Dalseo-gu, Daegu 42601, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chul-Hyun","family":"Cho","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Keimyung University Dongsan Hospital, Keimyung University School of Medicine, 1035 Dalgubeol-daero, Dalseo-gu, Daegu 42601, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hee-Uk","family":"Ye","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Keimyung University Dongsan Hospital, Keimyung University School of Medicine, 1035 Dalgubeol-daero, Dalseo-gu, Daegu 42601, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3580-4175","authenticated-orcid":false,"given":"Chang-Jin","family":"Yon","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Keimyung University Dongsan Hospital, Keimyung University School of Medicine, 1035 Dalgubeol-daero, Dalseo-gu, Daegu 42601, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hyeong-Uk","family":"Choi","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Keimyung University Dongsan Hospital, Keimyung University School of Medicine, 1035 Dalgubeol-daero, Dalseo-gu, Daegu 42601, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Young-Hun","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Keimyung University Dongsan Hospital, Keimyung University School of Medicine, 1035 Dalgubeol-daero, Dalseo-gu, Daegu 42601, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kwang-Soon","family":"Song","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Keimyung University Dongsan Hospital, Keimyung University School of Medicine, 1035 Dalgubeol-daero, Dalseo-gu, Daegu 42601, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,12,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.4055\/cios.2018.10.1.1","article-title":"Noise around the Knee","volume":"10","author":"Song","year":"2018","journal-title":"Clin.
