OBJECTIVE
The objective of the study was to evaluate the clinical and radiological results of internal fixation of patella fractures, comparing tension band wiring techniques with proximal only and proximally and distally bend Kirschner wires (K-wires).
METHODS
Over a period of 6 years, 60 patients met the criteria to be included in this study of which 40 were available for mid-term (2-8 years) clinical and radiological follow-up.
RESULTS
Out of 60, 9 failures of fixation occurred, 3 due to migration of the K-wires and 6 because of insufficient tensioning of the tension band. Failure due to migration, only occurred in the group with the proximally bend only K-wire technique.
CONCLUSION
Our recommendation is to distally bend the K-wires as well as proximally to prevent migration of K-wires.
目的
本研究旨在评估髌骨骨折内固定的临床和影像学结果，比较张力带钢丝技术与单纯近端和近端及远端弯曲克氏针（K 线）的效果。
方法
在 6 年期间，符合纳入本研究标准的 60 例患者中，有 40 例获得了中期（2-8 年）的临床和影像学随访。
结果
在 60 例患者中，有 9 例固定失败，其中 3 例是由于 K 线迁移，6 例是由于张力带张力不足。仅在单纯近端弯曲 K 线技术组中发生因迁移导致的固定失败。
结论
我们建议同时远端弯曲 K 线以及近端弯曲，以防止 K 线迁移。
