Krackow suturing and suture bridge technique was compared with Kirschner-Wire (K-wire) tension band and patella cerclage for the fixation of inferior pole patella fracture.
This was a retrospective study of 47 patients with inferior pole patella fractures who underwent fixation procedures at our hospital between January 2019 and May 2022, of whom 25 had Krackow suturing combined with the suture-bridge technique (GROUP 1), and 22 received a K-wire tension band combined with patellar cerclage (GROUP 2). We compared the operative time, reoperation rate, Böstman score, knee range of motion (ROM), fracture-healing time, Insall-Salvati index, complications and hospital expenses between the two groups.
The average follow-up period was 23.1 ± 5.8 months. The complication and reoperation rates in the GROUP 2 were significantly higher than those in the GROUP 1 (P = 0.023 and P < 0.001). While the GROUP 1 has lower hospital expenses than GROUP 2 (P < 0.001). However, significant differences were not found regarding the Böstman score, knee ROM, Insall-Salvati index, fracture-healing time, and operation time between the two groups.
Both Krackow suturing combined with the suture-bridge technique and the K-wire tension band technique can achieve comparable clinical efficacy in stably fixing inferior patellar pole fractures, subsequently allowing an early commencement of rehabilitation exercise, while the suture-bridge technique can also reduce the incidence of complications, hospital expenses and the need for reoperation surgery.

将Krackow缝合法与缝线桥技术、克氏针张力带及髌骨环扎术用于髌骨下极骨折固定进行比较。
这是一项回顾性研究，纳入了2019年1月至2022年5月期间在我院接受固定手术的47例髌骨下极骨折患者，其中25例采用Krackow缝合法联合缝线桥技术（第1组），22例采用克氏针张力带联合髌骨环扎术（第2组）。比较两组的手术时间、再次手术率、Böstman评分、膝关节活动范围（ROM）、骨折愈合时间、Insall-Salvati指数、并发症及住院费用。
平均随访时间为23.1±5.8个月。第2组的并发症和再次手术率显著高于第1组（P = 0.023和P < 0.001）。而第1组的住院费用低于第2组（P < 0.001）。然而，两组在Böstman评分、膝关节ROM、Insall-Salvati指数、骨折愈合时间及手术时间方面未发现显著差异。
Krackow缝合法联合缝线桥技术与克氏针张力带技术在稳定固定髌骨下极骨折方面可达到相当的临床疗效，随后可早期开始康复锻炼，而缝线桥技术还可降低并发症发生率、住院费用及再次手术的需求。
