中文摘要:
      目的 探讨经膝后内侧切口用锚钉治疗后交叉韧带(PCL)胫骨止点撕脱骨折的临床疗效。方法 收集2006年1月至2017年12月上海市闵行区中心医院骨科收治的PCL胫骨止点撕脱骨折患者52例,经膝关节后内侧入路,应用锚钉固定骨折块,术后2周行膝关节功能康复锻炼。记录手术时间、术中出血量、骨折愈合情况、膝关节活动度,应用Lysholm膝关节评分系统对术前及术后9个月膝关节功能进行评价。结果 所有患者均获9~14个月随访(平均11.4个月),骨折一期愈合时间8~14周。术后膝关节稳定,活动功能良好。后抽屉试验、Lachman试验均由阳性转为阴性,伸屈膝活动度正常。术前Lysholm评分为(59.4±6.0)分,关节活动度为(79.2±11.3)°。术后9个月Lysholm评分为(93.4±3.0)分,关节活动度为(137.3±5.9)°。因此术后Lysholm评分和膝关节活动度均优于术前,且均具有统计学意义(P<0.05)。结论 PCL胫骨止点撕脱骨折患者采用膝关节后内侧入路安全可靠,能术后早期功能锻炼,利于关节功能恢复。
英文摘要:
      Objective To investigate clinical effects of the surgical treatment for tibial avulsion fracture of the posterior cruciate ligament with anchor by posteromedial incision. Methods Fifty-two patients of tibial avulsion fracture of the posterior cruciate ligament were treated with suture anchor from January 2006 to December 2017. Functional exercises of the knee were conducted two weeks after operation. Record operation time, intro-operation blood-loss, time of bony union, range of motion of knee and Lysholm score at 9 months post-operation. Results All patients were followed up for 9~14 months with the average of 11.4 months. The bony union was achieved in 8~14 weeks. The results of posterior drawer test and reverse Lachman test were negative. The knee range of motion was recovered to normal level. Preoperatively, the Lysholm score was (59.4±6.0) point and the range of motion of the knee was (79.2±11.3)°. Meanwhile, the Lysholm score was (93.4±3.0) point and the range of motion of the knee was (137.3±5.9)°, 9 months postoperatively. Thus, both preoperative Lysholm score the preoperative range of motion of the knee were better than postoperative ones. Differences were statistically significant (P<0.05). Conclusion Posteromedial incision surgical treatment with suture anchor for avulsion fracture of the posterior cruciate ligament is safe and effective, it allows early postoperative rehabilitation exercises, so it can provide satisfactory function recovery of the knee joint.
