Cruciate ligament rupture is one of the most common orthopedic injuries in dogs, causing significant pain and lameness that requires surgical correction for full recovery.
CCL disease causes significant and often prolonged suffering. Acute rupture causes sudden-onset severe lameness — dogs often cannot bear weight on the affected limb. Without surgical intervention, the unstable joint sustains ongoing cartilage damage and develops debilitating arthritis within months. Dogs managed conservatively suffer from chronic pain that affects mobility, play, and quality of life. Post-surgical rehabilitation requires weeks of strict rest that frustrates active dogs and can cause psychological distress. The contralateral limb ruptures within 12–18 months in approximately 50% of affected dogs, meaning many dogs undergo two major surgeries and two lengthy recoveries. Early weight management, regular controlled exercise, and prompt surgical referral are the keys to minimizing suffering.
