Robotic-assisted TKA (RATKA) offers opportunities for improved soft-tissue balancing methods. This study aimed to evaluate the repeatability and reproducibility of ligamentous laxity assessments during RATKA using a digital tensioner.<\/jats:p>\n                  <jats:p>Three experienced RATKA surgeons assessed preresection and trialing phases of 12 human cadaveric knees with varying degrees of arthritis. Ligamentous laxity was assessed with manual varus and valgus stresses in extension and flexion, with a digital tensioner providing feedback on the change of laxity displacement. Intraclass correlation coefficient (ICC) analyses were used to determine the repeatability within a single surgeon and reproducibility between the three surgeons.<\/jats:p>\n                  <jats:p>The results showed excellent repeatability and reproducibility in ligamentous laxity assessment during RATKA. Surgeons had excellent repeatability for preresection and trialing assessments, with median ICC values representing excellent reproducibility between surgeons. Surgeons were repeatable within 1 or 1.5\u2009mm for preresection and trialing assessments. On average, the variation within a surgeon was 0.33\u2009\u00b1\u20090.26\u2009mm during preresection and 0.29\u2009\u00b1\u20090.28\u2009mm during trialing. When comparing surgeons to each other, they were reproducible within an average of 0.69\u2009\u00b1\u20090.33\u2009mm for preresection and 0.65\u2009\u00b1\u20090.31\u2009mm for trialing.<\/jats:p>\n                  <jats:p>This study demonstrated the reliability of robotic-assisted soft-tissue balancing techniques, providing control over ligamentous laxity assessments, and potentially leading to better patient outcomes. The digital tensioner used in this study provided excellent repeatability and reproducibility in ligamentous laxity assessment during RATKA, highlighting the potential benefits of incorporating robotics in TKA procedures.<\/jats:p>","DOI":"10.1055\/a-2232-7511","type":"journal-article","created":{"date-parts":[[2023,12,19]],"date-time":"2023-12-19T18:54:23Z","timestamp":1703012063000},"page":"607-611","source":"Crossref","is-referenced-by-count":22,"title":["Robotic-assisted Total Knee Arthroplasty Technology Provides a Repeatable and Reproducible Method of Assessing Soft Tissue Balance"],"prefix":"10.1055","volume":"37","author":[{"given":"Laura Y","family":"Scholl","sequence":"additional","affiliation":[{"name":"Stryker, Mahwah, New Jersey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Emily L.","family":"Hampp","sequence":"additional","affiliation":[{"name":"Stryker, Mahwah, New Jersey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Melanie","family":"Caba","sequence":"additional","affiliation":[{"name":"Stryker, Mahwah, New Jersey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ali","family":"Azhar","sequence":"additional","affiliation":[{"name":"Stryker, Mahwah, New Jersey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel","family":"Hameed","sequence":"additional","affiliation":[{"name":"Lifebridge Health, Sinai Hospital of Baltimore, Rubin Institute for Advanced Orthopedics, Baltimore, Maryland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeremy","family":"Dubin","sequence":"additional","affiliation":[{"name":"Lifebridge Health, Sinai Hospital of Baltimore, Rubin Institute for Advanced Orthopedics, Baltimore, Maryland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"James P.","family":"Crutcher","sequence":"additional","affiliation":[{"name":"Proliance Surgeons Inc, Seattle, Washington"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael A.","family":"Mont","sequence":"additional","affiliation":[{"name":"Rubin Institute for Advanced Orthopedics, Baltimore, Maryland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ormonde M.","family":"Mahoney","sequence":"additional","affiliation":[{"name":"Athens Orthopedic Clinic, Athens, Georgia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"194","published-online":{"date-parts":[[2024,3,4]]},"reference":[{"issue":"01","key":"ref1","doi-asserted-by":"crossref","first-page":"45","DOI":"10.1007\/s11999-009-0945-0","article-title":"The epidemiology of revision total knee arthroplasty in the United States","volume":"468","author":"K J Bozic","year":"2010","journal-title":"Clin Orthop Relat Res"},{"issue":"09","key":"ref2","doi-asserted-by":"crossref","first-page":"2663","DOI":"10.1016\/j.arth.2017.03.066","article-title":"Current epidemiology of revision total knee arthroplasty in the United States","volume":"32","author":"R E Delanois","year":"2017","journal-title":"J Arthroplasty"},{"issue":"04","key":"ref3","doi-asserted-by":"crossref","first-page":"780","DOI":"10.2106\/00004623-200704000-00012","article-title":"Projections of primary and revision hip and knee arthroplasty in the United States from 2005 to 2030","volume":"89","author":"S Kurtz","year":"2007","journal-title":"J Bone Joint Surg Am"},{"key":"ref4","doi-asserted-by":"crossref","first-page":"89","DOI":"10.4137\/CMAMD.S10859","article-title":"Clinical and economic burden of revision knee arthroplasty","volume":"5","author":"M Bhandari","year":"2012","journal-title":"Clin Med Insights Arthritis Musculoskelet Disord"},{"key":"ref5","doi-asserted-by":"crossref","first-page":"45","DOI":"10.1097\/01.blo.0000214421.21712.62","article-title":"Current etiologies and modes of failure in total knee arthroplasty revision","volume":"446","author":"K J Mulhall","year":"2006","journal-title":"Clin Orthop Relat Res"},{"issue":"404","key":"ref6","doi-asserted-by":"crossref","first-page":"7","DOI":"10.1097\/00003086-200211000-00003","article-title":"Insall Award paper.
