However, their efficacy in providing sufficient stability under different circumstances requires further investigation. The preclinical testing of prosthesis components on joint motion simulators is useful for quantifying how design changes affect joint stability. However, this type of testing may not be clinically relevant because surrounding ligaments are either ignored or greatly simplified. This study aimed to assess the kinematics and stability of TKA joints during various motions using condylar-stabilized (CS) bearings without a PCL versus cruciate-retaining (CR) bearings with an intact PCL. TKA prosthetic components were tested on a joint motion simulator while being stabilized with five different sets of specimen-specific virtual ligament envelopes. In comparison to CR knees, CS knees without a PCL exhibited a greater amount of posterior tibial displacement laxity, with a mean increase of 2.7\u00b12.1\u2009mm (p\u2009=\u20090.03). Additionally, significant differences were observed in the anterior\u2013posterior kinematics of the knee joint during activities of daily living (ADL) between the two designs. These results were consistent with previous cadaveric investigations, which indicated that CS knees without a PCL are less resistant to posterior tibial displacement than CR knees with one. This study employing virtual ligaments confirms previous findings that the raised anterior lip of some CS bearings may not completely compensate for the absence of the PCL; however, as both studies used reduced joint contact forces, the contributions of this design feature may be attenuated.<\/jats:p>","DOI":"10.1115\/1.4064621","type":"journal-article","created":{"date-parts":[[2024,3,26]],"date-time":"2024-03-26T06:52:23Z","timestamp":1711435943000},"update-policy":"https:\/\/doi.org\/10.1115\/crossmarkpolicy-asme","source":"Crossref","is-referenced-by-count":4,"title":["Comparison of the Kinematics and Laxity of Total Knee Arthroplasty Bearing Designs Stabilized With Specimen-Specific Virtual Ligaments on a Joint Motion Simulator"],"prefix":"10.1115","volume":"146","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7954-5086","authenticated-orcid":false,"given":"Samira","family":"Vakili","sequence":"first","affiliation":[{"name":"School of Biomedical Engineering, Western University , 1151 Richmond Street N, London, ON N6A 5B9, Canada ; , London, ON N6A 5B9, Canada"},{"name":"Western's Bone and Joint Institute, Western University , 1151 Richmond Street N, London, ON N6A 5B9, Canada ; , London, ON N6A 5B9, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brent","family":"Lanting","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, London Health Sciences Centre, University Hospital , 339 Windermere Road, London, ON N6A 5A5, Canada ; , London, ON N6A 5A5, Canada"},{"name":"Western's Bone and Joint Institute, Western University , 339 Windermere Road, London, ON N6A 5A5, Canada ; , London, ON N6A 5A5, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alan","family":"Getgood","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, London Health Sciences Centre, University Hospital , 339 Windermere Road, London, ON N6A 5A5, Canada ; , 3M Centre, London, ON N5A 3K7, Canada ; , London, ON N6A 5A5, Canada"},{"name":"Fowler-Kennedy Sport Medicine Clinic, Department of Surgery, Western University , 339 Windermere Road, London, ON N6A 5A5, Canada ; , 3M Centre, London, ON N5A 3K7, Canada ; , London, ON N6A 5A5, Canada"},{"name":"Western's Bone and Joint Institute, Western University , 339 Windermere Road, London, ON N6A 5A5, Canada ; , 3M Centre, London, ON N5A 3K7, Canada ; , London, ON N6A 5A5, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ryan","family":"Willing","sequence":"additional","affiliation":[{"name":"School of Biomedical Engineering, Western University , 1151 Richmond Street N, London, ON N6A 5B9, Canada ; , 1151 Richmond Street N, London, ON N6A 5B9, Canada ; , London, ON, Canada"},{"name":"Department of Mechanical & Materials Engineering, Western University , 1151 Richmond Street N, London, ON N6A 5B9, Canada ; , 1151 Richmond Street N, London, ON N6A 5B9, Canada ; , London, ON, Canada"},{"name":"Western's Bone and Joint Institute, Western University , 1151 Richmond Street N, London, ON N6A 5B9, Canada ; , 1151 Richmond Street N, London, ON N6A 5B9, Canada ; , London, ON, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"33","published-online":{"date-parts":[[2024,3,25]]},"reference":[{"issue":"5","key":"2024032606520593800_bib1","doi-asserted-by":"crossref","first-page":"1384","DOI":"10.1016\/j.arth.2017.11.037","article-title":"Prospective Randomized Comparison of Posterior-Stabilized Versus Condylar-Stabilized Total Knee Arthroplasty: Final Report of a Five-Year Study","volume":"33","year":"2018","journal-title":"J.
