What is Cruciate Disease?

Cruciate disease is when a dog (and sometimes a cat) ruptures or tears the anterior cruciate ligament (sometimes called the cranial cruciate ligament) which is located in the knee (stifle) joint. The cause can be traumatic but sometimes they just break and we are not sure of the reason why. We do know that obesity, poor physical conditioning, and early neutering all play a role in this disease. Researchers are looking for a possible genetic factor as well.

What do I do if my pet ruptures the ACL? We strongly believe that surgical repair is a must in these pets to allow more normal mobile, prevent a meniscus tears, and to avoid severe osteoarthritis within the joint.

How is it repaired? There are two general types of repairs that can be done: a constraining repair where an implant material is placed in or outside the joint that mimics the action of the torn ACL. Examples would be the Fastak, Corkscrew, and Tightrope, all names of the type of implant placed in the patient. The second type is mechanical modification repair where a procedure is done to neutralize the forces within the knee or stifle joint. Examples would be the Tibial Plateau Leveling Osteotomy (TPLO) or the Tibial Tuberosity Advancement (TTA).

We are offering a new TTA technique: This new surgical technique is called the Modified Maquet Procedure or MMP. When an MMP is done to modify the joint mechanics, we use a Titanium wedge implant instead of plates and screws. There is less movement of tissues during the surgery, a shorter surgery (and anesthesia) time, and we expect these patients to use the leg very soon after surgery. Although total healing time is 8 weeks, graduated leash walks are allowed beginning the day after surgery.

If your pet ruptures the ACL: Call for an appointment and we will be happy to discuss the options for repair and help you decide which procedure is best for you pet.
