The many factors contributing to patellar instability have led to various surgical techniques that are used commonly today. When surgery is deemed necessary, the operation should be tailored to the patient's specific pathoanatomy. Patients with malalignment can often be stabilized by moving the tibial tuberosity to a more medial, anteromedial, or distal position. Subsequent changes in the forces acting on the patellofemoral joint will depend on the direction and distance of the tuberosity repositioning. When planning tuberosity osteotomies, it is crucial to understand how to use clinical and imaging modalities to measure and quantify tuberosity position accurately to achieve the desired degree of realignment.
导致髌骨不稳定的因素众多，催生了如今常用的各种手术技术。当认为手术必要时，手术应根据患者的具体病理解剖结构进行调整。对线不良的患者通常可通过将胫骨结节移至更内侧、前内侧或远端位置来实现稳定。作用于髌股关节的力随后发生的变化将取决于结节重新定位的方向和距离。在规划结节截骨术时，关键是要了解如何运用临床和影像学方法准确测量和量化结节位置，以实现理想的对线程度。
