【摘要】 为探究犬髌骨内侧脱位（MPL）手术治疗效果、并发症和相关影响因素。本文回顾性分析了2007年3月—2022年6月在中国农业大学动物医院和新瑞鹏集团北京恒爱动物医院接受MPL矫正术的167只患犬（210例患肢手术）的病例信息和电话回访患肢跛行情况。结果显示，167只患犬中包括75只雌性（44.91%）和92只雄性（55.09%）；手术时患犬年龄中位数为2岁（4月龄～11岁）。体重小于15 kg的患犬157只（94.01%），大于15 kg的患犬10只（5.99%）;40例（19.05%）患肢进行侧韧带加固，98例（46.67%）进行滑车成形术，70例（33.33%）进行滑车成形术联合胫骨结节移位术（TTT）,2例（0.95%）进行TTT；总体手术结果良好率为86.83%(Ⅰ级、Ⅱ级、Ⅲ级、Ⅳ级MPL手术结果良好率分别为100%、90.10%、91.89%、54.17%);19例（11.45%）术后出现严重并发症，其中16例（9.64%）MPL复发。MPL等级对手术结果的影响具有统计学意义（OR=2.122,95%CI=1.142～3.942,P<0.05）。结果表明，手术对MPL的治疗效果良好，Ⅰ～Ⅲ级MPL的手术结果要优于Ⅳ级MPL。本文结果为临床MPL的诊疗提供一定的参考。更多还原

【Abstract】 This study aimed to investigate the surgical outcomes, postoperative complications, and influencing factors of medial patellar luxation(MPL) in dogs. A retrospective analysis was conducted on 167 dogs(210 limbs) that underwent corrective surgery for MPL at the China Agricultural University Veterinary Teaching Hospital and New Ruipeng Heng’ai Veterinary Hospital between March 2007 and June 2022. Telephone follow-ups were performed to assess postoperative lameness. Among the 167 dogs, 75 were female(44. 91%) and 92 were male(55. 09%). The median age at surgery was 2 years(ranging from 4 months to 11 years). A total of 157 dogs(94. 01%) weighed less than 15 kg, while 10 dogs(5. 99%) weighed more than 15 kg. Surgical procedures included lateral ligament reinforcement in 40 limbs(19. 05%), trochleoplasty in 98 limbs(46. 67%), trochleoplasty combined with tibial tuberosity transposition(TTT) in 70 limbs(33. 33%), and TTT alone in 2 limbs(0. 95%). The overall success rate of surgery was 86. 83%. By MPL grade, success rates were 100% for grade Ⅰ, 90. 10% for grade Ⅱ, 91. 89% for grade Ⅲ, and 54. 17% for grade Ⅳ. Severe postoperative complications occurred in 19 cases(11. 45%), including MPL recurrence in 16 cases(9. 64%). Statistical analysis indicated that MPL grade significantly influenced surgical outcomes(OR = 2. 122, 95% CI = 1. 142-3. 942, P < 0. 05). These results suggest that surgical treatment is generally effective for MPL in dogs, with better outcomes for grade Ⅰ–Ⅲ MPL compared to grade Ⅳ. This study provides useful reference data for the clinical diagnosis and treatment of MPL.更多还原
