[目的]评价锚钉技术治疗髌骨下极撕脱粉碎性骨折的疗效.[方法]回顾性分析本院2008年3月～2014年3月收治的髌骨下极撕脱粉碎性骨折患者26例(男19例,女7例),平均年龄(39±11)岁(26～54岁),均采用锚钉技术治疗.术后定期随访,采用膝关节活动度(range of motion,ROM)和Bostman评分系统评价膝关节功能康复情况.[结果] 26例中23例获得随访,术后平均随访(29±7)个月(19～46个月).末次随访时,患侧膝关节ROM为(129.35±7.19)°,健侧膝关节ROM为(132.69±6.11)°,两组间差异无统计学意义(P＞0.05),Bostman评分平均(28.41±2.13)分,优15例,良7例,差1例,优良率95.65％.[结论]锚钉技术结合张力带技术治疗髌骨下极撕脱粉碎性骨折操作简便,疗效确切,膝关节功能恢复好.“,”[Objective] To investigate the outcomes of suture anchor technique in the treatment of comminuted avulsion fractures of the inferior pole of the patella.[Methods] A retrospective analysis was performed on the clinical data of 26 patients.The patients,with comminuted avulsion fractures of the inferior pole of the patella,including 19 males and 7 female with a mean age of 39± 11 years,ranged 26-54 years,were admitted to our hospital and treated with the suture anchor technique from March 2008 to March 2014.The patients were followed up regularly after surgery.The range of motion (ROM) and Bostman scoring system were used to evaluate the knee function.[Results] Of the patients,23 were completely followed up for a mean of 29±7 months,ranged 19-46 months.At the final follow-up,the ROM of the knee joint on the injured side was 129.35°±7.19° and that on the uninjured side was 132.69°-±6.11°,and there was no significant difference in the ROM of the knee joint between the two sides (P ＞0.05).The mean Bostman score was 28.41±2.13.The results were graded as excellent in 15 patients,good in 7,and poor in 1 patient,associated with in an excellent and good rate of 95.65％.[Conclusions] The suture anchor technique combined with tension band is simple and convenient in the treatment of comminuted avulsion fractures of the inferior pole of patella,with a good clinical outcomes and good recovery of knee function.
