Although the cannulated screw and cable (CSC) tension band technique is an effective method for fixation of transverse patellar fractures, it has shortcomings, such as extensive soft tissue damage, osseous substance damage, and complex manipulation. We conducted a retrospective comparison of the adjustable patella grapple (APG) technique and the CSC tension band technique.
We retrospectively reviewed 78 patients with transverse patellar fractures (45 in the APG group and 33 in the CSC group). Follow-up was 18 months. Comparison criteria were operation time, fracture reduction, fracture healing time, the knee injury and osteoarthritis outcome score for knee function, and complications.
The APG group showed shorter operation time and equal fracture reduction, fracture healing time, and knee function compared with the CSC group. Eleven patients in the APG group experienced skin irritation generated by implants. There was no complication in the CSC group.
The APG technique should be considered as an alternative method for treatment of transverse patellar fractures.
尽管空心螺钉联合钢丝（CSC）张力带技术是治疗髌骨横行骨折的有效方法，但它存在诸如广泛的软组织损伤、骨质破坏和操作复杂等缺点。我们对可调式髌骨抓持器（APG）技术和CSC张力带技术进行了回顾性比较。
我们回顾性分析了78例髌骨横行骨折患者（APG组45例，CSC组33例）。随访时间为18个月。比较标准包括手术时间、骨折复位情况、骨折愈合时间、膝关节功能的膝关节损伤与骨关节炎疗效评分以及并发症。
与CSC组相比，APG组手术时间更短，骨折复位、骨折愈合时间及膝关节功能相当。APG组有11例患者出现植入物引起的皮肤刺激。CSC组无并发症发生。
APG技术应被视为治疗髌骨横行骨折的一种替代方法。
