Summary

Bioabsorbable interference screws provide reliable fixation for knee ligament reconstruction, significantly improving patient knee function and stability. This method is effective for procedures like anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) repair.

Area of Science:

  • Orthopedic Surgery
  • Biomaterials Science
  • Sports Medicine

Background:

  • Knee ligament injuries are common, impacting joint stability and function.
  • Traditional fixation methods may have limitations.
  • Bioabsorbable interference screws offer a potential alternative for graft fixation.

Purpose of the Study:

  • To evaluate the clinical outcomes of using bioabsorbable interference screws in knee ligament reconstruction.
  • To assess the efficacy and reliability of this fixation method.

Main Methods:

  • A cohort of 39 patients with various knee ligament injuries (ACL, PCL, collateral, posterolateral complex) underwent reconstruction.
  • Autografts were used for reconstruction.
  • Bioabsorbable interference screws were employed for graft fixation in arthroscopic or open procedures.

Main Results:

  • Follow-up of 34 patients over a mean of 13.7 months showed significant improvement in Lysholm knee scores (43.6 pre-op to 85.4 post-op).
  • No screw loosening or range of motion limitations were observed.
  • Minor complications included one infection and three cases of effusion/synovitis, which resolved with management.

Conclusions:

  • Bioabsorbable interference screw fixation is a dependable technique for knee ligament reconstruction.
  • This method effectively restores knee joint stability and function.
