To compare the clinical efficiency of patellar fixed pin and Kirschner's nail with tension band in treating patellar fracture.
From November 2010 to January 2012, the clinical data of 42 patients with patella fracture were treated with patella fixed needle and Kirschner's nail with tension band. The patellar fixed needle group included 21 cases (14 males and 7 females,aged 26 to 65 with an average of 43.6 years old); The Kirschner's nail with tension band group included 21 cases (12 males and 9 females,aged 32 to 58 with an average of 41.5 years old). The operation time, intra-operative blood loss and healing time were compared between two groups. Böstman score was applied to compare the therapeutic effects.
All patients were followed up with an average of 11.5 months ranged from 6 to 14 months. The fractures healed well without complications such as nonunion and infection. According to Böstman score, there was no significant difference between two groups in clinical efficiency (Z = -0.83, P = 0.407). There was significant difference in operation time (t = 6.67, P = 0.00), while no difference in intra-operative blood loss, bone healing time (t = 1.90, P = 0.064; t = 0.612, P = 0.544).
Both methods can obtain good results. However, patellar fixed pin combined with tension band is one of the ideal methods for the treatment of patellar fracture, it has an advantage of simple with shorter operation time, rigid fixation, less complications and well recovery.
比较髌骨固定针与克氏针张力带治疗髌骨骨折的临床疗效。
选取2010年11月至2012年1月间采用髌骨固定针和克氏针张力带治疗的42例髌骨骨折患者的临床资料。髌骨固定针组21例（男14例，女7例，年龄26～65岁，平均43.6岁）；克氏针张力带组21例（男12例，女9例，年龄32～58岁，平均41.5岁）。比较两组的手术时间、术中出血量及愈合时间。采用Böstman评分比较治疗效果。
所有患者均获随访，平均随访11.5个月（6～14个月）。骨折愈合良好，无骨不连、感染等并发症。根据Böstman评分，两组临床疗效差异无统计学意义（Z = -0.83，P = 0.407）。手术时间差异有统计学意义（t = 6.67，P = 0.00），而术中出血量、骨折愈合时间差异无统计学意义（t = 1.90，P = 0.064；t = 0.612，P = 0.544）。
两种方法均能取得良好效果。然而，髌骨固定针结合张力带是治疗髌骨骨折的理想方法之一，具有操作简单、手术时间短、固定牢固、并发症少、恢复良好等优点。
