Specifically, this method involves radioactive fluoroscopy, error\u2010prone goniometric measurements, and static joint angle outcomes that fail to approximate the compliance of tissues surrounding the joint. This study aims to validate a novel method of capturing the compliance of contracted tissues surrounding the joint without the use of fluoroscopy or animal sacrifice. Surgically induced contractures of one\u2010hundred and eight rabbits were measured using the current standard of contracture measurement (a pulley system) as well as a newly designed dynamic load cell (DLC) device. The DLC device was highly reliable when compared to the pulley system (<jats:italic>r<\/jats:italic>\u2009=\u20090.907, <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001). Finally, the DLC device produced joint stiffness hysteresis curves capable of approximating the compliance of stiff joint tissues, ultimately calculating a mean joint stiffness of 1.57\u2009\u00b1\u20091.31\u2009N\u2009\u00b7\u2009m\u2009\u00b7\u2009rad<jats:sup>\u22121<\/jats:sup> (range, 0.33\u20136.37\u2009N\u2009\u00b7\u2009m\u2009\u00b7\u2009rad<jats:sup>\u22121<\/jats:sup>). In conclusion, the DLC device represents a valid method for measuring joint contractures. Further, the DLC device notably improves current techniques by introducing the capacity to approximate the compliance of contracted tissues in living rabbits. \u00a9 2018 Orthopaedic Research Society.
