Meniscal allograft transplantation (MAT) with suture or bony fixation yields similar functional outcomes. Bony fixation showed a trend towards fewer complications and graft tears compared to suture-only fixation in this mid-term study.

Area of Science:

  • Orthopedic surgery
  • Sports medicine
  • Regenerative medicine

Background:

  • Meniscal allograft transplantation (MAT) is a viable option for restoring knee function after meniscectomy.
  • Graft fixation technique is crucial for successful MAT outcomes.
  • Comparing suture-only versus bony fixation for MAT is important for clinical decision-making.

Purpose of the Study:

  • To compare functional and radiographic results of meniscal allograft transplantation using two fixation techniques: suture-only versus bony fixation.
  • To evaluate complication rates and graft failure between the two fixation groups.

Main Methods:

  • Prospective comparative study of 88 meniscal allograft transplants (MAT) with a mean 5-year follow-up.
  • Grafts were fixed with either sutures (Group A, n=33) or bony fixation (Group B, n=55).

  • Functional outcomes assessed using Lysholm, Tegner, and VAS scores; radiographic evaluation for joint space narrowing.

    • Main Results:

    • Both fixation groups demonstrated significant improvements in functional scores (Lysholm, Tegner, VAS) with no significant differences between groups.
    • No significant joint space narrowing was observed radiographically in either group.
    • Group A (suture-only) had a higher complication rate (33.3%) including graft tears (21.4%) and allograft failure (9%) compared to Group B (bony fixation) (16.4% complications, 7.3% graft tears, 3.6% failure), though not statistically significant.

    Conclusions:

    • Meniscal allograft transplantation (MAT) with either suture or bony fixation provides comparable mid-term functional and radiographic results.
    • Bony fixation may be associated with a lower rate of complications and graft tears compared to suture-only fixation, warranting further investigation.
    • The choice of fixation technique may not significantly impact functional outcomes but could influence graft integrity and complication rates.
