Hamstring tendon harvesting for anterior cruciate ligament (ACL) reconstruction may impact knee flexion strength, especially with more tendons removed. Athletes requiring deep knee flexion should consider alternative graft choices.

Area of Science:

  • Orthopedic Surgery
  • Sports Medicine
  • Biomechanical Analysis

Background:

  • Anterior cruciate ligament (ACL) reconstruction frequently utilizes hamstring tendons due to reduced donor site morbidity.
  • Previous research suggested minimal impact on hamstring muscle performance post-harvesting, but recent findings indicate potential adverse effects.
  • A debate persists regarding the true influence of hamstring tendon harvesting on postoperative muscle function.

Purpose of the Study:

  • To comprehensively evaluate postoperative hamstring muscle performance after hamstring tendon harvesting for ACL reconstruction.
  • To assess various functional parameters including isokinetic strength and active knee flexion.

Main Methods:

  • A cohort of 58 patients undergoing ACL reconstruction were assessed post-surgery.

  • Isokinetic hamstring strength tests measured peak torque, total work, and peak torque angle.
  • Active knee flexion angle was also evaluated.
  • Patients were grouped based on graft type: semitendinosus (ST) only, ST and gracilis, or allogeneic fascia lata.

    • Main Results:

    • No statistically significant differences in peak torque or total work were observed compared to preoperative levels.
    • A correlation was found between the number of harvested hamstring tendons and a reduced active knee flexion angle.
    • Harvesting more tendons shifted the peak torque angle towards shallower flexion, indicating potential weakness at deeper angles.

    Conclusions:

    • ACL reconstruction with autologous hamstring tendons may not be optimal for athletes demanding deep or powerful knee flexion.
    • Consideration of graft choice is crucial for athletes whose performance relies on maximal knee flexion capabilities.
