Purpose:
This study aimed to compare the biomechanical properties of four meniscal suture configurations-two simple sutures (TSS), two cinch sutures, a locking loop stitch (LLS), and a delta-grip stitch (DGS)-for transtibial pullout repair of medial meniscus posterior root tears (MMPRTs) using porcine menisci.
Methods:
Forty porcine menisci were randomly assigned to each suture configuration with all-inside repair. All specimens were subjected to cyclic loading for 1000 cycles, followed by a load-to-failure test. We evaluated displacement after cyclic loading, the ultimate failure load and the mode of failure.
Results:
No significant differences in displacement were observed between the configurations (p = 0.709). The DGS exhibited significantly higher ultimate failure loads (281.4 ± 53.5 N) compared to TSS (166.8 ± 84.5 N) and the LLS (119.7 ± 46.7 N) (p = 0.006 and p < 0.001, respectively). Suture breakage was observed in the DGS group, while meniscus cutout was observed in the other suture configuration models.
Conclusion:
The results suggest that the DGS provides superior fixation strength and enhances MMPRT repair outcomes.
Level Of Evidence:
Level IV.
