The patellar bone is involved in repetitive, load bearing motion sequences every day and functions as a vectorial force translator. A fracture rate of 1% of all skeletal fractures is reported and surgical treatment often required. beside a direct trauma mechanism, indirect mechanism but as well as fatigue fractures after reconstructive knee surgery are published. The fracture management is dependent on the soft tissue condition and a variety of surgical options are known. new generation of low profile plates show promising results but the conventional cerclage wiring technique with K-wires is widely preferred. best functional results with sustainable stability are biomechanically seen after a combined fixation technique using anterior cerclage wiring with cannulated screw fixation. A definite algorithm of treatment of patellar bone fractures is yet not defied but a review of classification and surgical techniques should give assistance in decision making.
髌骨每天都参与重复性的负重运动序列，并作为矢量力转换器发挥作用。据报道，髌骨骨折占所有骨骼骨折的1%，通常需要手术治疗。除了直接创伤机制外，间接机制以及重建膝关节手术后的疲劳骨折也有相关报道。骨折的处理取决于软组织状况，已知有多种手术选择。新一代的薄型钢板显示出有前景的结果，但传统的克氏针环扎技术更受广泛青睐。在使用前路环扎钢丝结合空心螺钉固定的联合固定技术后，从生物力学角度看，能获得具有可持续稳定性的最佳功能结果。目前尚未确定髌骨骨折治疗的明确算法，但对分类和手术技术的综述应有助于决策。
