Tibial fixation of the anterior cruciate ligament hamstring tendon graft is commonly considered more problematic than femoral fixation. When interference screws are used for tibial hamstring tendon graft fixation, graft sometimes looses its tension, so a hybrid fixation (more than one method of fixation) must be applied. Biomechanical studies show that an implementation of interference screws combined with different indirect distal hamstring tendon fixation techniques can withstand much higher tearing forces when compared with one type of fixation. We made a technique of hybrid tibial fixation of the hamstring graft using round interference screws and an additional bi-cortical 4.5-mm diameter screw with a modified head that allows control over the initial tension of the graft.
前交叉韧带腘绳肌腱移植物胫骨固定通常被认为比股骨固定更成问题。当使用干扰螺钉进行腘绳肌腱移植物胫骨固定时，移植物有时会失去张力，因此必须采用混合固定（一种以上的固定方法）。生物力学研究表明，与单一固定方式相比，采用干扰螺钉并结合不同的间接远端腘绳肌腱固定技术可以承受更高的撕裂力。我们采用圆形干扰螺钉和另外一个带有改良头的双皮质 4.5 毫米直径螺钉对腘绳肌腱移植物进行混合式胫骨固定，这种改良头可以控制移植物的初始张力。
