由内而外的半月板修复术被广泛实施以保留半月板的功能。在该技术中，外部缝合线穿过囊以及外部半月板，而内部缝合线插入半月板。本研究的目的是从生物力学角度比较半月板-半月板和半月板-包膜缝合方法对于采用由内向外技术的纵向半月板撕裂的缝合稳定性。解剖27个猪膝关节，保留股骨-内侧囊/半月板-胫骨复合体，沿半月板圆周纤维切断内半月板，保留3mm宽度的外围半月板。将一根带有2-0聚酯缝合线的针插入半月板内部后，将另一根针以由内而外的方式穿过1）半月板周边（A组），2）半月板正上方的囊（B组），3）距半月板-囊交界处10mm处的囊（C组）。然后，手动将缝线系在胶囊上。测量了300次循环加载过程中修复部位的缝合间隙以及加载失效试验中的极限失效载荷。在单向方差分析之后，通过 Bonferroni 校正考虑每种组合中两组之间数据的统计显着性。循环加载试验中，A组缝线间隙为0.68±0.26mm，B组为1.08±0.36mm，C组为1.94±0.57mm，差异有统计学意义。载荷破坏试验中，A组极限破坏载荷为59.1±13.6N，B组为60.0±7.9N，C组为57.4±4.7N，差异无显着性。用于纵向半月板撕裂的由内而外技术中的缝合区域影响了撕裂部位的稳定性，并且缝合半月板的中间物质区域提供了响应循环拉伸载荷的良好稳定性。此外，缝合区域不影响最终失效载荷。在由内向外的半月板修复术中，外缝线应插入剩余的周边半月板或靠近半月板的囊内。
The inside-out meniscal repair is widely performed to preserve the function of meniscus. In this technique, the outer suture is passed through the capsule as well as the outer meniscus, while the inner suture is inserted into the meniscus. The aim of this study was to biomechanically compare the suture stability between meniscus-meniscus and meniscus-capsule suture methods for the longitudinal meniscal tear with inside-out technique. Twenty-seven porcine knees were dissected to maintain the femur-medial capsule/meniscus-tibia complex, and the inner meniscus was cut off along the meniscus circumferential fiber with 3 mm width of the peripheral meniscus preserved. After one needle with a 2-0 polyester suture was inserted into the inner portion of the meniscus, the other needle was inserted through 1) the peripheral meniscus (Group A), 2) capsule just above the meniscus (Group B), and 3) capsule at 10 mm apart from the meniscus-capsule junction (Group C) in the inside-out manner. Then, the suture was manually tied on the capsule. The suture gap at the repair site during 300 times of cyclic loading and the ultimate failure load in the load-to-failure test were measured. The statistical significance of the data between two groups in each combination was considered by Bonferroni correction, following a one-way analysis of variance. In the cyclic loading test, the suture gap was 0.68 ± 0.26 mm in Group A, 1.08 ± 0.36 mm in Group B, and 1.94 ± 0.57 mm in Group C with a significant difference. In the load-to-failure test, the ultimate failure load was 59.1 ± 13.6 N in Group A, 60.0 ± 7.9 N in Group B, and 57.4 ± 4.7 N in Group C, and there was no significant difference. The stitching region in the inside-out technique for longitudinal meniscal tear affected the stability of the tear site, and stitching the mid-substance region of the meniscus provides good stability in response to cyclic tensile loading. In addition, the stitching region did not affect the ultimate failure load. In the inside-out meniscal repair, the outer suture should be inserted into the remaining peripheral meniscus or the capsule near the meniscus.
