Cranial cruciate ligament rupture is the most common orthopedic injury in dogs, causing significant pain and requiring surgical intervention for lasting welfare restoration.
Cranial cruciate ligament rupture causes immediate severe lameness — affected dogs often cannot bear any weight on the affected leg. Without surgical stabilization, the joint continues to degenerate and arthritis progresses, causing permanent chronic pain. TPLO surgery has transformed outcomes for cruciate-injured dogs, with most returning to full or near-full athletic function. The welfare investment of surgery and rehabilitation is substantial but the alternative — progressive painful degeneration — makes it clearly the welfare-positive choice for affected dogs. Post-surgical rehabilitation through controlled walking, hydrotherapy, and physiotherapy significantly improves recovery speed and long-term joint health. Weight management is the most important preventive welfare measure, as obesity dramatically increases cruciate rupture risk.
