The cranial cruciate ligament stabilizes the stifle (knee) joint in dogs. Tearing or rupture of the CCL, analogous to an ACL tear in humans, is a common orthopedic issue in dogs. While ACL tears in humans often result from traumatic events, CCL ruptures in dogs are degenerative.
Genetics, obesity, gender, and immune-mediated diseases can contribute to the weakening of the CCL, leading to pain, lameness, and osteoarthritis (OA).
Traditionally, there are two routes for treating a CCL rupture: conservative management and surgical intervention. Conservative management may involve restricting exercise, rehabilitation, and possibly custom-fitted stifle braces.
Surgery is generally recommended for faster recovery and to reduce osteoarthritis progression. Surgical management at Fusion Veterinary Orthopedics typically begins with a minimally invasive arthroscopic procedure to confirm the tear and assess the meniscus and extent of OA.
The preferred surgical treatment is the tibial plateau leveling osteotomy (TPLO), which stabilizes the stifle by altering its biomechanics to eliminate the need for the CCL. This involves making a circular cut in the tibia, rotating it to flatten the slope, and securing it with a locking plate and screws. An expert in this procedure, Dr. David Dycus has performed over 7,000 TPLO procedures.
After surgery, initial rest is followed by prescribed home exercises and slow leash walking. Staples or sutures are removed around 2 weeks post-surgery, with X-rays and orthopedic exams at 8 and possibly 12 weeks to ensure proper healing.
Rehabilitation starts two weeks post-surgery and involves in-office sessions and at-home exercises to promote quicker healing, maintain muscle mass, and improve outcomes. Long-term management includes joint supplements, omega-3 fatty acids, maintaining a healthy weight, and staying active.
If you or your primary care veterinarian suspects your dog has a CCL rupture and would like us to evaluate their condition and recommend treatment, please schedule a consultation by calling 301.778.7781 or request an appointment online.
