Abstract: This study aimed to evaluate the surgical effect and complications of tibial plateau leveling osteotomy (TPLO) for cranial cruciate ligament disease (CCLD) in dogs, and analyze factors that affect surgical effect and complications. The medical records of canine CCLD treated by TPLO in China Agricultural University Veterinary Teaching Hospital were reviewed and followed up. The inclusion criteria are:follow-up time more than 5 months; case information record is completed. Results were as follows:101 TPLO procedures in 85 dogs of 20 breeds were included, including crossbreed (n=17, 20.0%), poodle (n=15, 17.7%), bichon (n=11, 12.9%), golden retriever (n=10, 11.8%) and Labrador retriever (n=8, 9.4%). The median weight and age were 14.4 kg (range, 4-53 kg) and 7 years (range, 1-14 years old), respectively. The overall complication rate was 37.6% (38/101). Thirty-six cases (35.6%, 36/101) had minor complications (including wound-related complications and bandage-related complications), and 2 cases (2.0%) had major complications (including 1case of screw loosening and 1 case of tibial tuberosity fracture). Wound-related complications (23.8%, 24/101) were more likely to occur in dogs with wound licking (P<0.01), which were found in all the 15 dogs with wound licking. Related complications occurred in 18 (34.6%) of 52 dogs treated with bandage. Two major complications were treated by revision surgery with good results. Among the cases with follow-up results, 95.6% (86/90) cases had good functional recovery. Besides, postoperative bandage increased the risk of complications (P=0.047, OR=3.873, 95%CI:1.015-14.776). However, no risk factors associated with surgical outcomes were found. In summary, TPLO of dogs with CCLD has desirable results and a low proportion of major complications. Licking can cause wound-related complications, therefore licking wounds should be strictly prevented postoperatively. Moreover, the use of bandages should be reduced to decrease associated complications.
