A common case of cranial cruciate ligament rupture
Wookie sustained a cranial cruciate ligament (CCL) rupture when out chasing his ball. The CCL is one of the main stabilizing ligaments of the stifle (knee) and so when it ruptures there is shifting between the femur and tibia with each step, preventing a dog from pushing off with the leg properly. This consistently leads to progressive arthritis. For these reasons, surgery to stabilize the stifle is recommended.
A ruptured CCL diagnosis is made by feeling the stifle and doing stability tests. Radiographs (X-rays) can show fluid effusion in the joint space.
TPLO (tibial plateau levelling osteotomy) is often recommended as the surgery of choice. This surgery corrects the joint surface slope of the tibia so the femur doesn’t slide off the back. A precisely planned curved cut is made in the top of the tibia, rotated to flatten the tibial joint surface, and then held in place with a bone plate and screws.
Wookie had a TPLO and is now back to running around and chasing his ball again. We expect a good prognosis with this surgery and 90% of dogs are able to reach excellent levels of activity, typically regaining the level of function they had before surgery.
