In vivo measurement of the dynamic 3-D kinematics of the ovine stifle joint.
The ovine stifle joint is a promising animal model for investigation of joint mechanobiology. A method for in vivo measurement of dynamic 3-D kinematics of the ovine stifle joint is described (accuracy: 0.36 +/- 0.39 mm). Inter-subject variability in kinematics is greater than both intra-subject and inter-session variability. For future studies in which joint kinematics are measured prior to and following controlled orthopaedic interventions, pooling of data should be avoided and each subject should act as its own control.
