关节镜下自体股四头肌腱-髌骨块单束重建后交叉韧带

摘要

目的：探讨以自体股四头肌腱-髌骨块为移植物在关节镜下单束重建后交叉韧带（PCL ）的临床疗效。方法：对21例PCL损伤患者以自体股四头肌腱-髌骨块为移植物，运用可吸收挤压螺钉固定法在关节镜下行PCL单束重建手术，以Lysholm评分、Tegner评分、国际膝关节文献委员会（IKDC）分级标准作为疗效评价指标。结果21例患者PCL重建及复合损伤手术治疗均顺利完成，无患者失访，术后所有患者主观症状均有明显改善，Lysholm评分、Tegner评分均较术前有明显提高，手术前后比较，差异有统计学意义（P＜0．01）。结论：以自体股四头肌腱-髌骨块为移植物单束重建PCL近期临床疗效满意，远期疗效需进一步对大样本的长期观察研究。%Objective To discuss the clinical effect of using autologous quadriceps tendon fixed by a patellar block as the graft to reconstruct posterior cruciate ligament (PCL ) under arthroscopy on a single-bundle way .Methods We treated 21 patients with damaged PCL using autologous quadriceps tendon fixed by a patellar block as the graft and absorbable interference screw fixation to reconstruct PCL under arthroscopy on a single-bundle way .Their functional recovery was evaluated by Lysholm scoring ,Tegner scoring and International Knee Documentation Committee (IKDC) criteria .Results All 21 patients got successful surgery on PCL reconstruction and multiple trauma ,no patients lost to follow-up .The subjective symptoms were improved after operation ,the post-operative Lysholm score and Tegner score were both significantly enhanced and showed statistical significance compared with the preoperative scores(P<0 .01) .Conclusion Using autologous quadriceps tendon fixed by a patellar block as the graft to reconstruct PCL on a single-bundle way leads to satisfactory short term clinical effects ,however ,the long term clinical effects remain to be eval-uated .
