dc.description.abstract | Laxity assessments are done before, during, and after intervention of knee injuries to assess potential outcomes. Study objectives were to create a method to define the passive kinematic limits, without artificially constraining coupled motion, and describe motion relative to them. The coupled envelopes of internal/external (IE), varus/ valgus (VV), and anterior/ posterior (AP) motion and a neutral path were used to describe loaded lunges and a simulated walk cycle. The envelopes were created by manual manipulation to motion limits. Lunges with ±3.3 Nm IE torques and ±4.7 Nm VV torque were used to verify the IE-VV coupled kinematic envelope. The IE envelope compared well, while the VV envelope was constantly offset. For six of the eight knees, a repeatable internal-valgus-anterior path relative to the center of laxity was observed for the walk cycle. All eight displayed an average anterior displacement outside the boundary at mid-stance of 4.3 ± 5.0mm. | |
