● Basic Information
· Name: Ya Tou
· Breed: Poodle

● Diagnosis

· Drawer Test: Positive
· Diagnosis: CCL rupture

● Treatment Plan
Intracapsular fixation using VetLuc ETButton for CCL reconstruction.
1. Establish a bone tunnel.
2. Pass the ETButton through the bone tunnel.
3. Use a tensioner to adjust the knee joint’s range of motion (ROM) to an appropriate level and secure it with a knot.
Trim excess sutures, completing the CCL reconstruction.

● Discussion & Conclusion
ETButton uses ultra-high molecular weight polyethylene (UHMWPE) sutures, a widely adopted material for artificial ligaments, offering:
· High wear resistance
· High tensile strength
· Low friction
· Excellent biocompatibility
Intracapsular fixation mimics the anatomical structure of the cranial cruciate ligament, replacing or reconstructing its function to restore knee joint stability. The use of UHMWPE ensures long-lasting joint stability and reduces the incidence of arthritis.
