Anterior cruciate ligament reconstruction does not necessarily
restore normal knee movement. Increased tibial rotation has previously been noted
during pivoting activities and may be due to the orientation of the anterior
cruciate ligament graft associated with traditional single bundle reconstruction
techniques. Recent research has shown that it is possible to limit rotation
during level walking using a single bundle anterior cruciate ligament
reconstruction. This study evaluated rotational knee kinematics during a pivot
task in a group of patients who had undergone anterior cruciate ligament
reconstruction using a single bundle technique and compared the findings to a
normal control group. METHODS: In 27 anterior cruciate ligament reconstruction
and 25 control participants, internal-external rotation was measured during a
descend stairs and pivot task in a gait laboratory. FINDINGS: Results showed that
the anterior cruciate ligament reconstruction patients had less internal tibial
rotation (for both range of rotation and maximum rotation) than the control
participants (effect size=0.7). INTERPRETATION: These results suggest that it is
possible to limit rotation after anterior cruciate ligament reconstruction using
a single bundle technique, even during a pivoting movement that places a high
rotational load at the knee joint. The positioning of the femoral tunnel in a
more anatomical position may be responsible for the reduced tibial rotation.
