[目的]探讨应用缝合锚钉固定法、Krackow缝合法缝合编织股四头肌腱固定法、Krackow缝合法缝合编织股四头肌腱并克氏针“8”字张力带钢丝固定三种不同方法治疗髌骨骨折的手术效果以及对膝关节功能的影响.[方法]60例髌骨上极骨折患者根据手术固定方法不同分为锚钉组、缝合组、张力带组各20例.锚钉组:应用缝合锚钌固定法治疗;缝合组:采用Krackow缝合法缝合编织股四头肌腱固定法;张力带组:Krackow缝合法缝合编织股四头肌腱并克氏针“8”字张力带钢丝固定法,分析比较三种不同内固定方法术后3、6个月的治疗效果以及对膝关节功能的影响.[结果]三组手术方法的平均术中及术后出血量、手术时间及住院时间比较,差异均无统计学意义(P＞0.05).术后3、6个月Lysholm膝关节活动评分,锚钉组和缝合组明显低于张力带组,差异有统计学意义(P＜0.05).[结论] Krackow缝合法缝合编织股四头肌腱并克氏针“8”字张力带钢丝固定治疗方法在解剖复位、坚强内固定加早期关节持续被动运动方面优于缝合锚钉固定法、Krackow缝合法缝合编织股四头肌腱固定法.“,”[Objective] To investigate the therapeutic effects of suture anchor fixation,Krackow suture and weave quadriceps tendon fixation,and Krackow suture and weave quadriceps tendon combined with Kirschner wire 8-type tension band plus steel wire fixation in the treatment of fracture of the superior patellar pole and their influence on knee joint function.[Method] Sixty patients with fracture of the superior patellar pole were divided into anchor group,suture group,and tension band group based on the method of fixation,each with 20 patients.Patients in the anchor group were treated by suture anchor fixation,patients in the suture group were treated by Krackow suture and weave quadriceps tendon fixation,and patients in the tension band group were treated by Krackow suture and weave quadriceps tendon combined with Kirschner wire 8-type tension band plus steel wire fixation.The therapeutic effects of the three methods of internal fixation and their influence on knee joint function were analyzed and compared at 3 and 6 months after surgery.[Result] There were no significant differences in average intraoperative and postoperative blood loss,operation time,and length of hospital stay between the three groups.According to the Lysholm scoring system for knee joint function at 3 and 6 months after operation,the scores were significantly lower in the anchor group and suture group than in the tension band group (P ＜0.05).[Conclusion] Compared with suture anchor fixation and Krackow suture and weave quadriceps tendon fixation,Krackow suture and weave quadriceps tendon combined with Kirschner wire 8-type tension band plus steel wire fixation has advantages in anatomical reduction,rigid internal fixation,and early continuous passive motion of knee joint.
