Fractures located at the inferior pole of the patella pose challenges in terms of fracture fixation, primarily due to inadequate bone quality at the lower pole and typically limited options for secure fixation. This study introduces a novel approach that involves employing the Krackow suture technique on the patellar tendon, followed by a longitudinal transosseous and upside-down fixation at the superior aspect of the patella using a suture anchor to address this challenge.
A retrospective cohort case series was conducted at a single center, involving ten patients with fractures at the lower pole of the patella. Follow-up assessments were performed for a minimum of six months to observe postoperative gap formation and evaluate bony union. Knee motion, pain, function, and any intra- and postoperative complications were documented throughout the follow-up periods.
All patients exhibited complete bone union without gap formation six months postoperatively, accompanied by a regained full range of motion without any functional limitations. No instances of postoperative anterior knee pain, refracture of the inferior patellar pole, or other complications were reported during the follow-up period.
The innovative technique involving longitudinal transosseous and upside-down suture anchor repair for the management of inferior patellar pole fractures is a straightforward and easily executable surgical procedure. This method offers stable fixation and yields favorable functional outcomes.
髌骨下极骨折在骨折固定方面存在挑战，主要原因是下极骨质质量欠佳且通常固定选择有限。本研究引入一种新方法，即在髌腱上采用Krackow缝合技术，然后使用缝线锚钉在髌骨上缘进行纵向经骨和倒置固定，以应对这一挑战。
在单一中心开展一项回顾性队列病例系列研究，纳入10例髌骨下极骨折患者。进行至少6个月的随访评估，观察术后间隙形成情况并评估骨愈合情况。在整个随访期间记录膝关节活动度、疼痛、功能以及任何术中及术后并发症。
所有患者术后6个月均实现完全骨愈合，无间隙形成，同时恢复了全范围活动且无任何功能受限。随访期间未报告术后膝前疼痛、髌骨下极再骨折或其他并发症的情况。
采用纵向经骨和倒置缝线锚钉修复治疗髌骨下极骨折的创新技术是一种简单且易于实施的手术方法。该方法提供稳定固定并产生良好的功能结果。
