Medially\u2010stabilized implants aim to more closely replicate normal knee motion than other implants following TKA, but no study has investigated knee laxity (motion under applied loads) and balance (i.e., difference in varus\/valgus motion under load) following medially\u2010stabilized TKA. The primary purposes of this study were to investigate how medially\u2010stabilized implants change knee laxity in non\u2010arthritic, cadaveric knees, and if it produces a balanced knee after TKA. Force\u2010displacement data were collected on 18 non\u2010arthritic cadaveric knees before and after arthroplasty using medially\u2010stabilized implants. Varus\u2010valgus and anterior\u2010posterior laxity and varus\u2010valgus balance were compared between native and medially\u2010stabilized knees at 0\u00b0, 20\u00b0, 60\u00b0, and 90\u00b0 under three different loading conditions. Varus\u2010valgus and anterior\u2010posterior laxities were not different between native and medially\u2010stabilized knees under most testing conditions (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009\u2265\u20090.068), but differences of approximately 2\u00b0 less varus\u2010valgus laxity at 20\u00b0 of flexion and 4\u2009mm more anterior\u2010posterior laxity at 90\u00b0 were present from native laxities (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009\n                      <jats:styled-content>&lt;<\/jats:styled-content>\n                      \u20090.017) Medially\u2010stabilized implant balance had \u22641.5\u00b0 varus bias at all flexion angles. Future studies should confirm if the consistent laxity afforded by the medially\u2010stabilized implant is associated with better and more predictable postoperative outcomes. \u00a9 2018 Orthopaedic Research Society.
