Abstract

The objective of this retrospective case series was to report overall peri-operative complications, short- to mid-term outcome, and owner satisfaction of closing tibial wedge osteotomy (CTWO) using locking compression plates, in dogs weighing <= 20 kg, for the treatment of cranial cruciate ligament disease. Medical records from 2015 to 2020 were reviewed for surgical technique, intraoperative findings, and complications. Pre- and postoperative radiographs were evaluated for healing, complications, and tibial plateau angles (TPAs). A follow-up telephone questionnaire was used to evaluate patient outcome and owner satisfaction. Eighty-one client-owned dogs (12.0 kg +/- 3.0 kg; 95% CI: 8.4 to 15.5) (N = 89 stifles) were included in the study. Mean tibial plateau angles at preoperative, postoperative, and 8-week follow-up were 29.7 degrees +/- 4.1 degrees (95% CI: 25.5 to 33.8), 6.7 degrees +/- 2.6 degrees (95% CI: 4.2 to 9.2), and 7.8 degrees +/- 2.4 degrees ( 95% CI: 4.9 to 10.6), respectively. Tibial plateau angles had significantly increased at the 8-week follow-up assessment by 1.04 degrees +/- 1.8 degrees; 95% CI: 20.8 to 22.8) compared to immediately postoperative. The postoperative complication rate was 4.49% (4 cases). Overall satisfaction was excellent with good return to limb function. Closing tibial wedge osteotomy can be performed in dogs <= 20 kg, using locking compression plates, achieving excellent overall owner satisfaction and return to function.
