Patellar ligament thickening is a recognized response following osteotomy of the proximal tibia as a treatment for cranial cruciate disease. In humans this is seen as a response to increased loading, but the reason for this thickening in dogs is unclear. A prospective study was undertaken to assess the degree and frequency of patellar ligament desmopathy in 25 consecutive cases undergoing tibial tuberosity advancement (TTA).
To determine the incidence of patellar ligament thickening following TTA.
Consecutive cases undergoing TTA had ultrasonographic and radiographic measurements performed of the patellar ligament, at multiple positions on the ligament. This was performed at the time of surgery, and at six weeks and six months (ultrasound only) following surgery. The radiographic measurements were performed by two reviewers who were blinded to the timeframe of each image.
There was great variation in both the incidence and degree of thickening of the ligament. Fifty percent of the cases showed no changes in the thickness of the patellar ligament. A clinical pain response was not associated with patellar ligament thickening. No statistically significant variables which predicted the development of patellar ligament thickening were identified .
The presence of signs of patellar ligament thickening is of questionable clinical significance and is probably an incidental finding.
髌韧带增厚是胫骨近端截骨术治疗颅交叉韧带疾病后公认的反应。在人类中，这被视为对负荷增加的反应，但犬类中这种增厚的原因尚不清楚。开展了一项前瞻性研究，以评估25例连续接受胫骨结节前移术（TTA）的病例中髌韧带疾病的程度和频率。
确定TTA术后髌韧带增厚的发生率。
对连续接受TTA的病例在髌韧带的多个位置进行超声和X线测量。在手术时以及术后六周和六个月（仅超声）进行测量。X线测量由两名对每张图像的时间范围不知情的审阅者进行。
韧带增厚的发生率和程度差异很大。50%的病例髌韧带厚度无变化。临床疼痛反应与髌韧带增厚无关。未发现预测髌韧带增厚发展的统计学显著变量。
髌韧带增厚迹象的存在临床意义存疑，可能是偶然发现。
