Patellofemoral instability is a common cause of knee pain that can lead to long-standing pain, chondral injury, recurrent dislocations, and degenerative changes if not treated appropriately. Tibial tubercle osteotomy is indicated when there is anatomy predisposing to patellar maltracking and instability, namely abnormal patellar height or tibial tubercle location. In this Technical Note, we describe a technique for tibial tubercle anteriorization and distalization as part of the overall treatment algorithm for patellar instability with associated patella alta. This method of tibial tubercle osteotomy reliably produces anterior and distal translation of the patella to correct patellar height and decrease contact pressure across the patellofemoral joint.
髌股关节不稳定是膝关节疼痛的常见原因，如果治疗不当，可导致长期疼痛、软骨损伤、复发性脱位和退行性改变。当存在导致髌骨轨迹不良和不稳定的解剖结构，即髌骨高度异常或胫骨结节位置异常时，需行胫骨结节截骨术。在本技术说明中，我们描述了一种胫骨结节前移和下移技术，作为伴有高位髌骨的髌股关节不稳定整体治疗方案的一部分。这种胫骨结节截骨术能可靠地使髌骨向前和向下移位，以纠正髌骨高度并降低髌股关节的接触压力。
