The advent of robotic-assisted TKA (RA-TKA) allows for objective knee laxity measurements. The purpose of this study was to compare knee laxity measurements in RATKA patients with and without reported noise generation.<\/jats:p>\n <\/jats:sec>\n \n Materials and Methods:<\/jats:title>\n This was a single-institution, retrospective study of 133 patients who underwent primary unilateral RA-TKA from 2018 to 2021. Patients completed a survey consisting of four Likert scale questions related to prosthesis noise, the Forgotten Joint Score (FJS), and the Knee Injury and Osteoarthritis Outcome Score-Joint Replacement (KOOS, JR). Intraoperative laxity measures were obtained from the robotic system and compared between patients who did and did not report noise generation.<\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n \n Of the patients, 57.9% did not report noise and 42.1% did report noise. There were no significant differences in medial extension laxity (1.7 mm vs 1.8 mm;\n P<\/jats:italic>\n = .454), lateral extension laxity (1.9 mm vs 2.0 mm;\n P<\/jats:italic>\n = .567), medial flexion laxity (2.2 mm vs 2.0 mm;\n P<\/jats:italic>\n = .419), and lateral flexion laxity (2.7 mm vs 2.9 mm;\n P<\/jats:italic>\n = .307). Compared to patients who reported noise, those who did not had significantly higher satisfaction (94.8% vs 37.5%;\n P<\/jats:italic>\n < .001), postoperative KOOS, JR scores (79.2% vs 69.7%;\n P<\/jats:italic>\n = .005), and FJSs (60.3 vs 44.2;\n P<\/jats:italic>\n = .002). Patients who felt noise also had higher satisfaction (90.0% vs 41.5%,\n P<\/jats:italic>\n < .001).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion:<\/jats:title>\n While prosthesis-generated noise symptoms affect satisfaction following TKA, variability in knee laxities does not seem to significantly affect whether a patient will experience noise following TKA.<\/jats:p>\n <\/jats:sec>","DOI":"10.3928\/01477447-20260225-01","type":"journal-article","created":{"date-parts":[[2026,3,26]],"date-time":"2026-03-26T13:12:47Z","timestamp":1774530767000},"source":"Crossref","is-referenced-by-count":0,"title":["Variations in Laxity After Total Knee Arthroplasty Do Not Affect Prosthesis-generated Noise"],"prefix":"10.3928","volume":"49","author":[{"given":"Nicholas F.","family":"Cozzarelli","sequence":"first","affiliation":[{"name":"Hackensack University Medical Center, Department of Orthopaedic Surgery, Hackensack, New Jersey;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alexandra L.","family":"Hohmann","sequence":"additional","affiliation":[{"name":"Rothman Orthopaedic Institute at Thomas Jefferson University, Philadelphia, Pennsylvania;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Irfan A.","family":"Khan","sequence":"additional","affiliation":[{"name":"Louisiana State University Health New Orleans, Department of Orthopaedic Surgery, New Orleans, Louisiana"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Musa B.","family":"Zaid","sequence":"additional","affiliation":[{"name":"Sutter Health Orthopedics, Daly City, California."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jess H.","family":"Lonner","sequence":"additional","affiliation":[{"name":"Rothman Orthopaedic Institute at Thomas Jefferson University, Philadelphia, Pennsylvania;"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2308","reference":[{"key":"e_1_3_1_2_2","doi-asserted-by":"publisher","DOI":"10.2106\/JBJS.17.01617"},{"key":"e_1_3_1_3_2","doi-asserted-by":"publisher","DOI":"10.1007\/s11999-009-1119-9"},{"key":"e_1_3_1_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.arth.2017.07.021"},{"key":"e_1_3_1_5_2","doi-asserted-by":"publisher","DOI":"10.1097\/01.blo.0000238825.63648.1e"},{"key":"e_1_3_1_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.arth.2010.10.009"},{"key":"e_1_3_1_7_2","doi-asserted-by":"publisher","DOI":"10.1007\/s11999-016-4701-y"},{"key":"e_1_3_1_8_2","doi-asserted-by":"publisher","DOI":"10.1055\/s-0032-1319779"},{"key":"e_1_3_1_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.arth.2020.03.005"},{"key":"e_1_3_1_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.arth.2022.03.075"},{"key":"e_1_3_1_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ocl.2020.12.001"},{"key":"e_1_3_1_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.artd.2020.12.022"},{"key":"e_1_3_1_13_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.arth.2023.02.023"},{"key":"e_1_3_1_14_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00402-021-04067-9"},{"key":"e_1_3_1_15_2","doi-asserted-by":"publisher","DOI":"10.1055\/s-0041-1731349"},{"key":"e_1_3_1_16_2","doi-asserted-by":"publisher","DOI":"10.1055\/s-0039-1700837"},{"key":"e_1_3_1_17_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00167-021-06464-4"},{"key":"e_1_3_1_18_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00167-016-4076-3"},{"key":"e_1_3_1_19_2","doi-asserted-by":"publisher","DOI":"10.1055\/s-0040-1718603"},{"key":"e_1_3_1_20_2","doi-asserted-by":"publisher","DOI":"10.1097\/CORR.0000000000000916"},{"key":"e_1_3_1_21_2","doi-asserted-by":"publisher","DOI":"10.52628\/88.1.07"},{"key":"e_1_3_1_22_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00167-014-3108-0"},{"key":"e_1_3_1_23_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00402-018-2965-2"},{"key":"e_1_3_1_24_2","doi-asserted-by":"publisher","DOI":"10.1080\/17453674.2018.1554400"},{"key":"e_1_3_1_25_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.arth.2016.12.043"},{"key":"e_1_3_1_26_2","doi-asserted-by":"publisher","unstructured":"McEwen P Balendra G Doma K.
