Plain-English summary
A group of dogs that underwent a surgical procedure called the modified Maquet procedure to treat knee problems were evaluated to see how well the surgery worked. The study found that the actual advancement of the tibial tuberosity (a part of the knee) was about 30% less than what was planned, which means the surgery didn't achieve the desired angle for the patellar ligament. Despite this, the changes in the knee structure remained stable eight weeks after surgery. This suggests that current planning methods may not be effective in achieving the necessary adjustments for optimal recovery.

Abstract
OBJECTIVES: 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. METHODS: 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. RESULTS: 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. CLINICAL RELEVANCE: 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.
