Plain-English summary
A 5-year-old Labrador with a torn cranial cruciate ligament (CCL) was treated with a surgical procedure called CORA-based leveling osteotomy (CBLO) to help improve his knee stability. Before the surgery, he had noticeable limping and difficulty walking, but after the procedure and a recovery period of six months, his lameness significantly improved. The surgery helped reduce abnormal movement in his knee, and he was able to walk more normally, showing a marked improvement in his overall mobility.

Abstract
OBJECTIVE: The purpose of this study was to quantify three-dimensional (3D) stifle kinematics during walking in dogs with complete cranial cruciate ligament insufficiency (CCL-I) treated with a CORA-based leveling osteotomy (CBLO). STUDY DESIGN: Four client-owned dogs with unilateral complete CCL-I were prospectively enrolled. Custom digital 3D models of the femora and tibiae were created from pre-and postoperative computed tomographic scans for each dog. Lateral view fluoroscopic images were collected during treadmill walking preoperatively and 6 months after CBLO. Results were generated using a 3D-to-2D image registration process. Pre-and postoperative stifle kinematics (craniocaudal translation, extension angle) were compared to that of the unaffected contralateral (control) stifle. Force plate gait analysis was performed, and symmetry indices (SI) were calculated for peak vertical force (PVF) and vertical impulse (VI). RESULTS: After CBLO, craniocaudal femorotibial motion was reduced by a median (range) of 43.0 (17.0-52.6) % over the complete gait cycle. Median (range) PVF SI was 0.49 (0.26-0.56) preoperatively and 0.92 (0.86-1.00) postoperatively, and VI SI was 0.44 (0.20-0.48) preoperatively and 0.92 (0.82-0.99) postoperatively. CONCLUSION: CBLO mitigated but did not fully resolve abnormal craniocaudal translation; lameness was substantially improved at 6 months.
