Cranial cruciate ligament rupture is the most common orthopedic injury in dogs, requiring surgery and extensive rehabilitation for full recovery.
CCL rupture causes acute pain and significant lameness that substantially impacts quality of life. Dogs compensating for a ruptured CCL develop abnormal gait patterns that stress other joints and muscles. Surgical intervention is the current standard of care for most dogs, but the procedure is expensive and the recovery period lengthy. Dogs require restricted activity for 8-12 weeks post-surgery, which can cause boredom and frustration. Insufficient rehabilitation leads to suboptimal outcomes. Without treatment, chronic pain from progressive arthritis causes ongoing suffering.
