Abstract

PURPOSE

We use magnetic resonance angiography to evaluate the difference of vascular ingrowth to the bone tunnel on the anterior and posterior walls quantitatively after anterior cruciate ligament reconstruction.

MATERIALS AND METHODS

One hundred patients underwent anterior cruciate ligament reconstruction with multi-stranded semitendinosus tendons. They were retrospectively divided into those who underwent magnetic resonance angiography 2, 3, 4 to 6, and ≥ 7 months after surgery. The mean signal-to-noise ratios of the bone tunnel walls in the femur and tibia from the digital data were measured and compared for the anterior and posterior walls.

RESULTS

The signal-to-noise ratio of the posterior wall of the femoral bone tunnel was significantly higher than that of the anterior wall in each group. On the tibial side, the signal-to-noise ratio of the anterior wall was significantly higher than that of the posterior wall at ≥4 months after surgery.

CONCLUSIONS

This study showed that the blood flow after anterior cruciate ligament reconstruction to the femoral bone tunnel is maintained from the posterior wall, and is maintained to the tibial side from the anterior wall 4 months postoperatively. Revascularization to the bone tunnel wall after anterior cruciate ligament reconstruction may relate to the distance from the vessels.

摘要

目的

我们使用磁共振血管造影术定量评估前交叉韧带重建术后血管向内生长至股骨隧道前后壁的差异。

材料与方法

100例患者接受了多股半腱肌腱前交叉韧带重建术。他们被回顾性地分为术后2、3、4至6以及≥7个月接受磁共振血管造影术的患者。测量并比较来自数字数据的股骨和胫骨骨隧道壁的平均信噪比，比较前后壁的情况。

结果

每组中股骨骨隧道后壁的信噪比均显著高于前壁。在胫骨侧，术后≥4个月时前壁的信噪比显著高于后壁。

结论

本研究表明，前交叉韧带重建术后股骨骨隧道的血流从后壁维持，术后4个月时胫骨侧的血流从前壁维持。前交叉韧带重建术后骨隧道壁的血管再生可能与血管距离有关。
