Adding a lateral extraarticular reconstruction to a standard single bundle anterior cruciate ligament (ACL) reconstruction significantly reduces tibial internal rotation compared to double bundle ACL reconstruction. This technique offers improved biomechanical control for ACL deficient knees.

Area of Science:

  • Orthopedic Surgery
  • Biomechanics
  • Sports Medicine

Background:

  • Anatomic anterior cruciate ligament (ACL) reconstruction using double bundle grafts aims to improve biomechanical outcomes, particularly during rotational loading.
  • Extra-articular tenodesis techniques are explored to supplement intra-articular ACL reconstruction, reducing tibial internal rotation (IR) and anterior translation.

Purpose of the Study:

  • To evaluate the effect of a lateral extra-articular reconstruction on tibial IR when added to a standard single bundle ACL reconstruction.
  • To compare this combined technique against an anatomic double bundle ACL reconstruction using computer-assisted navigation.

Main Methods:

  • Twenty male patients undergoing ACL reconstruction were divided into two groups: Group A (single bundle ACL + lateral extra-articular reconstruction) and Group B (double bundle ACL reconstruction).

  • All procedures utilized doubled gracilis and semitendinosus tendon grafts and arthroscopically assisted techniques.
  • Computer-assisted navigation was employed to assess global knee kinematic performance, including anterior-posterior (AP) displacement, IR, and external rotation (ER).

    • Main Results:

    • Both techniques significantly reduced AP displacement, IR, and ER compared to the pre-operative ACL-deficient state (p<0.05).
    • No significant differences in AP displacement, IR, or ER were found when comparing single bundle ACL reconstruction (Group A) with the AM bundle fixation of double bundle ACL reconstruction (Group B).
    • While AP displacement and ER showed no significant difference between Group A (with lateral tenodesis) and Group B (with PL bundle fixation), Group A demonstrated a significant reduction in tibial IR (p=0.0001).

    Conclusions:

    • The addition of a lateral extra-articular reconstruction to a standard single bundle ACL reconstruction with hamstring tendons is more effective in reducing tibial IR at 30 degrees of knee flexion.
    • This combined approach provides superior control of internal tibial rotation compared to both standard single bundle ACL reconstruction and anatomic double bundle ACL reconstruction.
