Conformational deformities of the knee such as patella laxation contribute to repeated stress on the CCL, obesity increases the stress on support structures, animals over 5 years of age demonstrate a decrease in strength and stiffness of these structures, animals that have ruptured one CCL are more inclined to rupture the opposite side in 1 to 3 years, and finally immune mediated diseases may weaken and eventually lead to complete failure of one or both CCLs.
A ruptured ACL or CCL is the most common knee injury of dogs; in fact in most cases a sudden lameness of the hind limb tends to be a ruptured cruciate until proven otherwise.
The most common signs include: sudden pain of the hind limb, swelling of the knee, instability of the knee, or hindlimb weakness. The key to diagnosis of a ruptured cruciate ligament is the presence of a type of knee instability called a cranial drawer sign.
This is where the tibia moves forward on palpation from the femur like the motion of a drawer being opened. Often in large painful dogs this test is best performed when the dog is sedated to allow for the knee to be completely relax. Other important supportive diagnostics used may include: radiographs, MRI, and arthroscopic surgery.
Rupture of the cruciate ligament results in progressive and degenerative changes with in and around the joint, therefore surgery is the most proven and consistent way to treat a ruptured ACL. Historical data also demonstrates that dogs that start with a partial ACL tear almost always result in a full ACL tear in a matter of weeks or a few months.
Surgeries that are commonly performed can be divided into intra-articular versus extra-articular and arthroscopy versus arthrotomy. North Specialty temporarily closed North Emergency: North Emergency: After Hours Emergency.
The most common signs of a CCL injury include: Limping or lameness Favoring one leg over another Exercise intolerance, such as reluctance to go on walks or tiring easily Difficulty climbing stairs Reluctance to jump into the car or onto furniture Sitting slowly and not putting the affected leg squarely underneath While easily spotted by trained eyes, the hallmark signs of a CCL injury are not always noticeable to pet owners and often missed as a result.
What Are the Treatment Options? In addition to reviewing the costs of a surgical procedure, pet parents must also consider their expectations long term after the surgery, as well as their ability to provide the immediate postoperative care Types of CCL Surgery There are three primary types of surgery that restore stability to the knee joint: Extracapsular repair: This procedure aims to artificially replace the ligament with a heavy nylon suture across the outer part of the joint.
The goal of this procedure is to make your pet comfortable with return to low stress activities like walking. The goal of this procedure is to return normal function and full athletic activity like chasing squirrels, jumping on and off the coach, jogging or anything more strenuous than a short walk. It provides a comfort and activity level similar to the extracapsular repair.
The goal is to eliminate the sliding movement and stabilize the joint by realigning the two bones connecting the knee joint. This is done by cutting the top of the tibia and moving it forward.
Nonsurgical Options for CCL Injuries Nonsurgical options for CCL injuries include: Weight loss: Extra pounds put additional pressure on the joints, so weight management through nutrition and exercise is key. Braces: Braces try to immobilize the knee and ankle to relieve pain; however, they provide only minor support.
It is important to select one specifically designed for dogs for best results. Laser therapy: Also known as cold laser therapy, this noninvasive procedure uses deep-penetrating light to stimulate cell regeneration and increase blood circulation.
Acupuncture: Acupuncture can be used to stimulate the nervous system, reduce inflammation, and promote healing.
These modalities may also be used adjunctively in surgical patients to promote healing. The abnormal motion can also cause the meniscus within the knee to tear Conclusion If you notice your dog is limping or has long-term pain or mobility issues, please call your primary care veterinarian right away.
