To evaluate the patellar ligament to tibial plateau angle (PL-TPA) and amount of achieved advancement in dogs that underwent the modified Maquet procedure; compare wedge sizes recommended using two different planning techniques (Orthomed and modified tibial tuberosity advancement); and evaluate anatomical factors that predict the wedge size required to obtain a 90° PL-TPA.
Pre- and postoperative radiographs of dogs that had a modified Maquet procedure performed were evaluated for the following: calculated wedge size using two different planning techniques, the actual wedge size used, the achieved tibial tuberosity advancement, and the changes in PL-TPA. Anatomical measurements of the tibia were evaluated and correlated with the actual wedge size.
Of the 38 modified Maquet procedures identified, 53% (n = 20) had a PL-TPA of 90° ± 5°. Actual achieved advancement of the tibial tuberosity was 30% less than the wedge size used. Changes in PL-TPA and tibial width persisted at eight weeks postoperatively without loss of advancement. The two planning techniques did not result in a significantly different selection of wedge size.
Current planning techniques for the modified Maquet procedure result in under-advancement of the tibial tuberosity. Both measurement techniques evaluated do not result in appropriate advancement.
评估接受改良Maquet手术的犬髌韧带至胫骨平台角（PL - TPA）及实现的前移量；比较使用两种不同规划技术（Orthomed和改良胫骨结节前移术）推荐的楔形尺寸；并评估预测获得90° PL - TPA所需楔形尺寸的解剖学因素。
对接受改良Maquet手术的犬术前和术后X线片进行如下评估：使用两种不同规划技术计算的楔形尺寸、实际使用的楔形尺寸、实现的胫骨结节前移量以及PL - TPA的变化。评估胫骨的解剖学测量值并与实际楔形尺寸进行关联。
在确定的38例改良Maquet手术中，53%（n = 20）的PL - TPA为90°±5°。胫骨结节实际实现的前移量比使用的楔形尺寸少30%。术后8周时，PL - TPA和胫骨宽度的变化持续存在，前移量未丢失。两种规划技术在楔形尺寸选择上无显著差异。
改良Maquet手术目前的规划技术导致胫骨结节前移不足。所评估的两种测量技术均未实现适当的前移。
