Background: Rotational knee movement after reconstruction of the anterior cruciate ligament has been difficult to quantify. The purpose of this study was to identify in vivo whether a more horizontal placement of the femoral tunnel (in the ten o'clock position rather than in the eleven o'clock position) can restore rotational kinematics, during highly demanding dynamic activities, in a knee in which a bone-patellar tendon-bone graft had been used to reconstruct the anterior cruciate ligament.

Methods: We evaluated ten patients in whom a bone-patellar tendon-bone graft had been used to reconstruct the anterior cruciate ligament with the femoral tunnel in the …

The Effects Of Gender On The Biomechanics Of The Hip During Athletic Maneuvers, Mikaela Boham

Boise State University Theses and Dissertations

Context: Females are two to eight times more likely to sustain an ACL injury than males participating in the same sport. The primary mechanism reported for noncontact ACL injury involves landing from a jump, unanticipated change of direction, and/or deceleration activities.

Objective: The purpose of this study was to determine if adolescent female athletes perform athletic activities with decreased hip and knee flexion angles, and decreased EMG activity of the gluteus medius relative to their male counterparts.

Design: Cohort study from local club basketball teams.

Setting: University Laboratory.

Participants: Ten healthy adolescent basketball athletes (5 females, 5 males).

Interventions: Each …

Anterior Cruciate Ligament Reconstruction With A Quadrupled Hamstrings Tendon Autograft Does Not Restore Tibial Rotation To Normative Levels During Landing From A Jump And Subsequent Pivoting, Vasilis Chouliaras, Stavros Ristanis, Constantina O.

Aim. Recent research suggested that the anterior curciate ligament (ACL) reconstruction does not restore tibial rotation to normal levels when a bone patellar tendon bone (BPTB) graft is used during high demanding activities. Our goal was to determine if the usage of an alternative graft, as the quadrupled semitendinosus-gracilis (ST/G), restore tibial rotation to normal values in a population of athletically active individuals while performing a usual for their sport activity.

Methods. Eleven subjects, all reconstructed with an ST/G graft, were assessed in vivo, 9 months postoperatively, while they jumped off a 40 cm platform, landed on the ground and …
