How Should We Secure Our Transplanted Meniscus? A Meta-Analysis
Purpose: To assess meniscal allograft transplantation (MAT) outcomes and compare the results of different root fixation techniques through systematic literature review.
- The optimal root fixation (soft tissue suture vs. bone replacement) for MAT is debated
- A total of 38 studies with a mean follow-up of 60 months were included for analysis
- In the overall cohort of 1637 MATs, there were no significant differences found between either fixation technique
- Meniscal tear rates were similar as evidenced in 13.4% of soft-tissue sutures and 14.9% of bone fixations
- Allograft failures were also similar with 17.6% failure in soft tissue suture and 18.8% failure with bone fixation
- Lysholm and VAS scores significantly improved pre-operatively to final follow-up for either technique
JRF Ortho Take Away: The significant overall improvements in function and pain scores accompanied by low allograft failure rates suggest that MAT is a reliable option. The current data does not demonstrate a difference in fixation method which may suggest that it does not have a significant influence on clinical outcome.
