title: Sagittal knee kinematics after hamstring lengthening.
abstract: The purpose of this study was to analyze sagittal knee kinematics after hamstring lengthening. A retrospective analysis was performed of 16 children (32 knees) with cerebral palsy who underwent hamstring lengthening as an isolated surgical procedure. Gait analysis was performed before surgery and at a minimum of 1 year after surgery. Decreased stance maximum knee flexion, stance minimum knee flexion, swing maximum knee flexion, and swing minimum knee flexion were noted. Total knee excursion increased. The present study confirmed the previously reported increased total knee excursion with decreased stance minimum and swing maximum knee flexion.
