An inferior pole fracture of the patella requires surgical treatment to restore the knee extension mechanism of the knee joint. Different from other types of patellar fractures, inferior pole fractures are usually comminuted, and other traditional fixation methods, such as tension band wiring, may not meet the fixation needs. We propose fixing inferior pole fractures of the patella with a custom-made anchor-like plate combined with cerclage and report the surgical outcomes.
This is a retrospective clinical study. From June 2018 to August 2020, 21 patients with inferior patella fracture treated at Hong Hui Hospital Affiliated to Xi'an Jiaotong University received a custom-made anchor-like plate combined with cerclage. Complications of the surgical fixation methods and final knee function were used as the main outcome measures.
All fractures achieved good union, and the union time ranged from 8 to 12 weeks. No patients had serious complications, such as internal fixation failure or infection. The average duration of surgery of patients was 75.05 7.26 min, and the intraoperative blood loss was 60.099.49 ml. At the last follow-up, the range of motion of the knee was 120°-140°, with an average of 131.436.92°, the Bostman score was 27-30, and the Lysholm score ranged from 82 to 95. All patients showed good knee function one year after the operation.
We used a modified T-shaped plate combined with cerclage technology to fix inferior fractures pole of the patella, providing reliable fixation, allowing early functional exercise of the knee joint, and providing patients with good knee joint function after surgery.
髌骨下极骨折需要手术治疗以恢复膝关节的伸膝机制。与其他类型的髌骨骨折不同，髌骨下极骨折通常是粉碎性的，其他传统的固定方法，如张力带钢丝固定，可能无法满足固定需求。我们提出使用定制的锚状钢板结合环扎术固定髌骨下极骨折，并报告手术结果。
这是一项回顾性临床研究。2018 年 6 月至 2020 年 8 月，西安交通大学附属红会医院收治了 21 例髌骨下极骨折患者，采用定制的锚状钢板结合环扎术治疗。手术固定方法的并发症和最终膝关节功能作为主要观察指标。
所有骨折均愈合良好，愈合时间为 8 至 12 周。无患者发生内固定失败或感染等严重并发症。患者的平均手术时间为 75.057.26 分钟，术中出血量为 60.099.49 毫升。末次随访时，膝关节活动度为 120°-140°，平均 131.436.92°，Bostman 评分为 27-30 分，Lysholm 评分为 82-95 分。所有患者术后 1 年膝关节功能良好。
我们使用改良 T 形钢板结合环扎技术固定髌骨下极骨折，提供可靠的固定，允许膝关节早期功能锻炼，并为患者提供术后良好的膝关节功能。
