Abstract

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.

内侧半月板水平劈裂撕裂修复后的序列磁共振形态学改变

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。
