Although tibial tuberosity (TT) transfer has for many years been the basis of many protocols for the management of patellar instability, the role of pure medial transfer in particular appears to be declining. In contrast, the greater recognition of the importance of patella alta as a predisposing factor to recurrent patellar dislocation has resulted in a resurgence in the popularity of distal TT transfer. When TT transfer is performed, the direction and amount of transfer is based on the patellar height and the lateralization of the TT relative to the trochlear groove. Patellar height is best assessed on a lateral radiograph with the knee in flexion using a ratio that uses the articular surface of the patella in relation to the height above the tibia. Assessment of lateralization of the TT relative to the trochlear groove can be made using either computed tomography or magnetic resonance imaging scans.
尽管多年来胫骨结节（TT）转移一直是许多髌骨不稳定治疗方案的基础，但单纯内侧转移的作用尤其似乎在下降。相比之下，对高位髌骨作为复发性髌骨脱位易感因素重要性的更多认识，导致了远端TT转移的再度流行。当进行TT转移时，转移的方向和量基于髌骨高度以及TT相对于滑车沟的侧方移位情况。髌骨高度最好在膝关节屈曲的侧位X线片上进行评估，使用一个基于髌骨关节面相对于胫骨上方高度的比值。TT相对于滑车沟侧方移位的评估可使用计算机断层扫描或磁共振成像扫描。
