Fractures of the inferior patellar pole, unlike other patellar fractures, present challenges for traditional surgical fixation methods. This article introduces the clinical technique and outcomes of using Kirschner wire tension band combined with anchor screw cross-stitch fixation for comminuted inferior patellar pole fractures.
This retrospective case series study included 14 patients with comminuted inferior patellar pole fractures treated at our institution from September 1, 2020, to April 30, 2022. All patients underwent surgery using the Kirschner wire tension band with anchor screw cross-stitch technique. Follow-up assessments involved postoperative X-rays to evaluate fracture healing, as well as clinical parameters such as healing time, Visual Analog Scale (VAS) scores, range of motion (ROM), and Bostman scores.
All patients were followed for an average of over 12 months, with no cases of internal fixation failure. Knee joint stability and function were excellent. X-rays revealed an average healing time of approximately 10.79 ± 1.53 weeks, hospitalization lasted 5.64 ± 1.15 days, surgery took approximately 37.86 ± 5.32 minutes, and intraoperative blood loss was 33.29 ± 8.15 ml. One patient experienced irritation from the internal fixation material. At the final follow-up, the Bostman score averaged 28.29 ± 0.83, knee joint flexion reached 131.07° ± 4.88°, all patients achieved full knee extension, and the VAS score was 0.36 ± 0.63.
Kirschner wire tension band with anchor screw cross-stitch fixation for comminuted inferior patellar pole fractures delivered satisfactory clinical outcomes. This surgical method, characterized by its simplicity and reliability, is a valuable addition to clinical practice.
与其他髌骨骨折不同，髌骨下极粉碎性骨折对传统的手术固定方法提出了挑战。本文介绍了使用克氏针张力带联合锚钉十字缝线固定治疗髌骨下极粉碎性骨折的临床技术和疗效。
本回顾性病例系列研究纳入了 2020 年 9 月 1 日至 2022 年 4 月 30 日在我院治疗的 14 例髌骨下极粉碎性骨折患者。所有患者均采用克氏针张力带联合锚钉十字缝线技术进行手术。术后通过 X 线评估骨折愈合情况，并通过临床参数（如愈合时间、视觉模拟评分（VAS）、关节活动度（ROM）和 Bostman 评分）进行随访评估。
所有患者平均随访超过 12 个月，无内固定失败病例。膝关节稳定性和功能均良好。X 线显示平均愈合时间约为 10.79±1.53 周，住院时间为 5.64±1.15 天，手术时间约为 37.86±5.32 分钟，术中出血量为 33.29±8.15ml。1 例患者出现内固定材料刺激。末次随访时，Bostman 评分为 28.29±0.83，膝关节屈曲度为 131.07°±4.88°，所有患者均获得完全膝关节伸直，VAS 评分为 0.36±0.63。
克氏针张力带联合锚钉十字缝线固定治疗髌骨下极粉碎性骨折可获得满意的临床疗效。这种手术方法简单可靠，是临床实践的有益补充。
