**Intraoperative identification of the tibial intercondylar eminence in dogs is often inaccurate.**
The study aimed to evaluate the precision of intraoperative identification of the tibial intercondylar eminence (TIcE) in the sagittal plane during canine knee surgeries. Accurate localization of the TIcE is crucial for procedures like tibial plateau leveling osteotomy (TPLO), which is commonly performed to treat cranial cruciate ligament (CCL) injuries in dogs. The research involved a cohort of dogs undergoing TPLO, with the surgical team attempting to identify the TIcE intraoperatively. Postoperative imaging, such as radiographs or computed tomography (CT) scans, were then used to assess the accuracy of the intraoperative identification. The findings revealed a significant discrepancy between the intraoperative identification and the postoperative imaging results, indicating a high rate of misidentification. This suggests that relying solely on intraoperative identification of the TIcE may not be sufficient for precise surgical planning in TPLO procedures. The study emphasizes the need for additional imaging techniques or preoperative planning to enhance the accuracy of TIcE localization, thereby improving surgical outcomes and reducing the risk of complications associated with misalignment. Further research is recommended to explore alternative methods or technologies that could assist surgeons in more accurately identifying the TIcE during canine knee surgeries.
