In Vivo Biomechanics: Laxity Versus Dynamic Stability

  • Yuichiro Nishizawa
  • Scott TashmanEmail author


Musahl et al. described laxity as the passive response of a joint to an externally applied force or torque in biomechanical terms [60]. Thus, laxity tests for evaluating knee injury assess the passive limits of motion in a particular direction or plane. Through comprehensive laxity testing, it is possible to describe the range of a passive envelope of motion that the joint can achieve within the limits of the low forces typically employed for such testing.
