This study utilized a large cadaveric collection to explore relationships between tibial slope and coronal plane deformity of the tibia. We utilized 462 well-preserved skeletons (924 tibiae), excluding any with fracture or obvious rheumatologic or infectious findings. Custom cards were made with different sized arcs on the bottom surface, so that they could rest on the anterior and posterior aspects of the medial and lateral tibial plateaus of each bone to measure PPTA. Previously measured MPTA values for the same bones were also utilized. Multiple regression analysis was used to determine relationship between MPTA and medial and lateral PPTAs. The mean age was 56\u2009\u00b1\u200910 years, with 13% female and 31% African American (remainder Caucasian). The mean MPTA was 87.2\u2009\u00b1\u20092.4 degrees. The mean medial plateau PPTA was 81.5\u2009\u00b1\u20093.8 degrees and mean lateral plateau PPTA was 81.3\u2009\u00b1\u20093.7 degrees. Regression analysis found that MPTA was significantly associated with both medial and lateral PPTAs (standardized betas 0.197 and 0.146, respectively, p\u2009&lt;\u20090.0005 for both). There was a significant correlation between lateral and medial PPTAs (r\u2009=\u20090.435, p\u2009=\u20090.03). The clinical significance of these findings warrants further investigation and emphasizes the importance of carefully assessing the sagittal plane when planning reconstruction of a tibia with varus or valgus deformity, particularly high tibial osteotomies.<\/jats:p>","DOI":"10.1055\/s-0041-1728816","type":"journal-article","created":{"date-parts":[[2021,4,29]],"date-time":"2021-04-29T01:54:39Z","timestamp":1619661279000},"page":"062-067","source":"Crossref","is-referenced-by-count":5,"title":["A Cadaveric Anatomical Study of the Relationship between Proximal Tibial Slope and Coronal Plane Deformity"],"prefix":"10.1055","volume":"36","author":[{"given":"Julia","family":"Foos","sequence":"additional","affiliation":[{"name":"Division of Pediatric Orthopaedic Surgery, Rainbow Babies & Children's Hospital, Case Western Reserve University, Cleveland, Ohio"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0076-0945","authenticated-orcid":false,"given":"Kouami","family":"Amakoutou","sequence":"additional","affiliation":[{"name":"Division of Pediatric Orthopaedic Surgery, Rainbow Babies & Children's Hospital, Case Western Reserve University, Cleveland, Ohio"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel R.","family":"Cooperman","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery and Rehabilitation, Yale School of Medicine, New Haven, Connecticut"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Raymond W.","family":"Liu","sequence":"additional","affiliation":[{"name":"Division of Pediatric Orthopaedic Surgery, Rainbow Babies & Children's Hospital, Case Western Reserve University, Cleveland, Ohio"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"194","published-online":{"date-parts":[[2021,4,28]]},"reference":[{"key":"ref1","doi-asserted-by":"crossref","DOI":"10.1007\/978-3-642-59373-4","volume-title":"Principles of Deformity Correction","author":"D Paley","year":"2002","edition":"1st ed."},{"issue":"07","key":"ref2","doi-asserted-by":"crossref","first-page":"2158","DOI":"10.1016\/j.arthro.2018.01.055","article-title":"Effect of increased coronal inclination of the tibial plateau after opening-wedge high tibial osteotomy","volume":"34","author":"Y Akamatsu","year":"2018","journal-title":"Arthroscopy"},{"issue":"02","key":"ref3","doi-asserted-by":"crossref","first-page":"376","DOI":"10.1177\/0363546503258880","article-title":"Effects of increasing tibial slope on the biomechanics of the knee","volume":"32","author":"J R Giffin","year":"2004","journal-title":"Am J Sports Med"},{"issue":"09","key":"ref4","doi-asserted-by":"crossref","first-page":"1443","DOI":"10.1177\/0363546507304665","article-title":"Importance of tibial slope for stability of the posterior cruciate ligament deficient knee","volume":"35","author":"J R Giffin","year":"2007","journal-title":"Am J Sports Med"},{"issue":"05","key":"ref5","doi-asserted-by":"crossref","first-page":"745","DOI":"10.1302\/0301-620X.76B5.8083263","article-title":"Tibial translation after anterior cruciate ligament rupture.
