摘要

目的探讨由外向内垂直缝合技术修复水平劈裂撕裂（hct）的序列磁共振成像（MRI）的愈合率及术后变化。方法入选2019年11月至2022年10月期间接受hct半月板修复的30例患者。手术采用由外至内的垂直缝合，使用一根脊髓针和带两个穿梭继电器的缝合钩。术前、术后即刻和术后2年分别用MRI测量矢状半月板宽度（SMW）和矢状半月板高度（SMH）。结果与术前相比，术后即刻MRI显示SMW降低，SMH升高，形成梯形。然而，随着时间的推移，术后2年的MRI显示与术后立即的MRI相比，宽度增加，高度下降，这表明这有助于重塑成三角形。结论由外向内垂直缝合技术用于hct的临床效果良好，术后MRI连续检查显示修复后的hct愈合成功。

Morphological changes observed on serial magnetic resonance imaging of repaired medial meniscal horizontal cleavage tears

Aim

To investigate the healing rate and postoperative changes on serial magnetic resonance imaging (MRI) of horizontal cleavage tears (HCTs) repaired using outside-in vertical suture technique.

Methods

Thirty patients who underwent meniscal repair for HCTs between November 2019 and October 2022 were enrolled. Surgeries were performed using outside-in vertical sutures with a spinal needle and suture hook with two shuttle relays. The sagittal meniscal width (SMW) and sagittal meniscal height (SMH) were measured using MRI preoperatively, immediately postoperatively, and 2 years postoperatively.

Results

Compared with preoperative MRI, immediate postoperative MRI revealed decreased SMW and increased SMH, resulting in a trapezoidal shape. However, over time, the 2-year postoperative MRI showed increased width and decreased height compared with the immediate postoperative MRI, suggesting that this contributes to remodeling into a triangular shape.

Conclusion

The outside-in vertical suture technique for HCTs showed good clinical outcomes and successful healing of the repaired HCTs on serial postoperative MRI.
