However, current methods to assess whether the surgeon achieved their desired reduction in the tension of a released ligament are subjective and/or do not provide a quantitative metric of tension in an individual ligament. Accordingly, the purpose of this study was to determine whether shear wave tensiometry, a novel method to assess tension in individual ligaments based on the speed of shear wave propagation, can detect changes in ligament tension following incremental releases. In seven medial and eight lateral collateral porcine ligaments (MCL and LCL, respectively), we measured shear wave speeds and ligameJournal of orthopaedic research : official publication of the Orthopaedic Research SocietyShear wave tensiometry tracks reductions in collateral ligament tension due to incremental releases.PMC9759618R21EB024957R21 EB024957Blomquist MBRoth JDSchmitz DGBlank JLThelen DGfalseShear wave tensiometry tracks reductions in collateral ligament tension due to incremental releases.Surgeons routinely perform incremental releases on overly tight ligaments during total knee arthroplasty (TKA) to reduce ligament tension and achieve their desired implant alignment.
