A Cranial Closing Wedge Ostectomy (CCWO) has been recommended for your dog as the most appropriate method of surgical treatment for cranial cruciate ligament (CCL) disease, which is often the result of a degenerative process in dogs.
It is frequently noticed after running, playing or jumping. The damage to the cranial cruciate ligament leads to instability and pain in the affected limb.
Many surgical treatment options are available for managing CCL disease, however, CCWO is recommended as the most appropriate treatment option for smaller dogs, based on the shape and size of their tibia (shin bone).
During each surgery a complete assessment of the joint is necessary to assess the damaged cruciate ligament and the joint menisci (these mini, shock absorbing cartilage pads provide rotational knee stability).
An accurately measured wedge of bone is cut and removed from the tibia. The two edges of bone are then brought together(closed) and a metal plate is applied to secure and stabilize the osteotomy site. This results in a levelling out of the tibial joint surface, preventing the femur slipping backwards.
Whilst there is no cure for CCL disease in dogs, the goals of treatment are to relieve pain, improve function by stabilisation and reduce the progression of arthritis. Surgery, in combination with exceptional postoperative care and rehabilitation can significantly improve the outcome and prognosis for dogs with CCL disease.
