Cranial Cruciate Ligament Rupture in Dogs
Cranial Cruciate Ligament Rupture is a high-severity orthopedic condition that can affect dogs of all ages and breeds. The cranial cruciate ligament (CCL) stabilises the knee joint. Rupture — often partial then complete — is one of the most common orthopaedic injuries in dogs, leading to instability, pain, and rapid joint degeneration. It is documented across 5 breeds, though prevalence and severity can differ significantly between them. It typically becomes apparent at 4-7 years. Early signs to watch for include sudden hind limb lameness, toe-touching or non-weight bearing, swollen knee joint, and sitting with leg out to side. When treatment is required, costs are estimated at £2,500-£5,500 depending on severity, location, and the specific intervention needed. Cranial Cruciate Ligament Rupture has a hereditary component, so health-screening certificates from the breeder are strongly recommended for predisposed breeds. This page covers symptoms, treatment options, and preventive steps — along with breed-specific information where available.
