Although isolated posterior cruciate ligament (PCL) injuries often can be treated successfully without surgical intervention, in the setting of persistent instability or multiligamentous knee injury, PCL reconstruction is indicated. PCL reconstructions often have resulted in persistent postoperative laxity. Recent research suggests there may be a role for suture tape-augmented grafts, which have demonstrated decreased clinical and radiographic laxity as well as improved rates of return to previous level of activity, as compared with PCL reconstruction alone. Several biomechanical studies also have supported the use of suture tape augmentation in PCL reconstruction, and the use of suture tape augmentation or internal bracing and ligament surgery is gaining widespread popularity. These ultrahigh molecular weight polyethylene/polyester suture tapes have been shown to be safe and effective. We may be at the point at which the evidence supports the use of suture tape augmentation of PCL reconstruction.
虽然孤立的后交叉韧带(PCL)损伤通常可以在不进行手术干预的情况下成功治疗,但在持续不稳定或多韧带膝关节损伤的情况下,需要进行 PCL 重建。PCL 重建后常出现持续的术后松弛。最近的研究表明,缝线带增强移植物可能有一定的作用,与单独的 PCL 重建相比,缝线带增强移植物显示出较低的临床和放射学松弛度以及更高的恢复到先前活动水平的比率。几项生物力学研究也支持在 PCL 重建中使用缝线带增强,缝线带增强或内部支撑和韧带手术的使用越来越普及。这些超高分子量聚乙烯/聚酯缝线带已被证明是安全有效的。我们可能正处于证据支持 PCL 重建中使用缝线带增强的阶段。
