Abstract
Background
Biomechanical assessment of meniscal repairs is essential for evaluating different meniscal suturing methods and techniques. The continuous meniscal suture technique is a new method of meniscal repair and has not yet been biomechanically evaluated.
Purpose
To evaluate the displacement, stiffness after cyclical loads, and load to failure for a continuous vertical inside-out meniscal suture versus a traditional vertical inside-out meniscal suture in a porcine medial meniscus.
Study Design: Controlled Laboratory Study
Methods
Thirty porcine knees were acquired and divided into two test groups of 15 knees each. A 2.0 cm longitudinal red-white zone transition lesion was created in the body of the medial meniscus of all knees. The continuous suture (CS) group (group A) received four vertical stitches performed with a continuous vertical meniscal suture technique, and the traditional suture (TS) group (group B) received a traditional vertical suture with four stitches.
Results
The displacement after a cyclic test was 0.52 ± 0.12 mm and 0.48 ± 0.07 for the CS and TS groups, respectively. No significant differences were observed between both groups (p = 0.3108). In the load-to-failure test, the ultimate load was 219.9 ± 61.6 N and 238.3 ± 71.3 N in the CS and TS groups, respectively. There were no significant differences between both groups (p = 0.4623). The system's stiffness at the last cycle was 36.2 ± 1.8 N/mm and 35.3 ± 2.4 N/mm for groups A and B, respectively. The two groups had no significant difference (p = 0.2340).
Conclusion
A continuous vertical meniscal suture created a beneficial configuration for treating longitudinal meniscal lesions, biomechanically similar to a traditional vertical suture technique. Therefore, the continuous vertical suture technique appears to be a good option for the surgical treatment of longitudinal tears of the medial meniscus.
