Cruciate Ligament Rupture (CCL)

A cranial cruciate ligament (CCL) rupture, often referred to as an ACL tear in humans, is a common injury in dogs, particularly larger breeds. The cruciate ligament is crucial for stabilizing the knee joint, preventing the shin bone from sliding forward relative to the thigh bone. When it ruptures, partially or completely, the joint becomes unstable, causing pain, lameness, and swelling. This instability often leads to the development of osteoarthritis if not treated. Surgical intervention is typically recommended to restore stability and reduce long-term complications, with various techniques available depending on the dog's size and activity level. Without surgery, many dogs will continue to experience pain and develop significant arthritis.
