The modified Kessler stitch offers the strongest fixation for meniscal root tears, but no tested method fully restores native root strength. Caution is advised during rehabilitation after meniscal root repair.

Area of Science:

  • Orthopedic surgery
  • Biomechanical analysis
  • Sports medicine

Background:

  • Meniscal root tears are increasingly recognized.
  • Effective fixation is crucial for successful rehabilitation and preventing early failure.
  • Suture fixation techniques are commonly employed for meniscal root repair.

Purpose of the Study:

  • To compare the maximum failure load of native human meniscal roots.
  • To evaluate the biomechanical strength of three common meniscal root fixation techniques: 2 simple stitches, modified Kessler stitch, and loop stitch.
  • To determine if current fixation methods can restore the native strength of meniscal roots.

Main Methods:

  • A controlled laboratory study design was utilized.
  • The maximum failure load of 64 human native meniscal roots (anteromedial, posteromedial, anterolateral, posterolateral) was assessed.

A Novel Arthroscopic Medial Knot-Tying Suture-Bridge Repair with Rip-Stop Technique for Rotator Cuff Tears

Published on: January 13, 2026

  • The failure load of 24 meniscal roots repaired with 2 simple stitches, modified Kessler stitch, or loop stitch was evaluated.

    • Main Results:

    • The native anterolateral meniscal root exhibited the highest failure load, while the anteromedial root was significantly weaker.
    • Among fixation techniques, the modified Kessler stitch demonstrated the greatest maximum failure load, followed by the loop stitch and then the 2 simple stitches.
    • None of the evaluated fixation techniques successfully replicated the strength of the native meniscal roots.

    Conclusions:

    • The anterolateral meniscal root is biomechanically the strongest, and the anteromedial root is the weakest.
    • The modified Kessler stitch provides superior primary fixation strength compared to loop and simple stitch techniques.
    • Current meniscal root fixation methods do not restore native root strength, necessitating careful rehabilitation protocols.
