Modified Maquet Procedure (MMP Surgery)
Dogs are playful animals that love to run, jump and chase. If you notice that your pet is limping or struggling to walk, they may be struggling with cranial cruciate ligament (CCL) failure. Similar to a human’s ACL, this crucial band of tough tissue stabilizes your dog’s knee joint. If torn or ruptured, a CCL injury allows the tibia to shift in front of the thigh bone when walking or even standing.
Cruciate ligaments can only be repaired surgically. One of the best options for the surgical repair of a CCL tear is the Modified Maquet Procedure (MMP). At Indian Ridge Animal Hospital, our surgical director, Dr. Matt Mears, specializes in MMP surgery. If you’ve noticed that your dog is limping, favoring their other leg or seems to be struggling with chronic pain, then it’s time to schedule your appointment.
Indian Ridge Animal Hospital is located in Kingsport, Tennessee, and we accept patients and vet clinic referrals from the surrounding area. Please fill out our contact form to learn more about MMP surgery and the other high-quality services available at our pet clinic.
What Is the Modified Maquet Procedure (MMP)?
If your dog experiences a CCL tear, this injury will not heal without surgical intervention. In years past, your vet may have recommended Tibial Tuberosity Advancement (TTA) or Tibial Plateau Levelling Osteotomy (TPLO). Although these are both well-established treatments, MMP surgery is considered the best CCL repair procedure for dogs with a torn CCL, especially those over 38 pounds.
The Modified Maquet Procedure (MMP) is a minimally invasive, simplified version of TTA surgery. When you bring your dog to Indian Ridge Animal Hospital, Dr. Mears will consider the patient’s unique situation before recommending a course of treatment.
Here are a few reasons Dr. Mears may recommend MMP over TPLO or TTA:
- MMP offers shortened surgery times
- The procedure requires only one bone cut
- Patients experience minimal pain
- Recovery time is shorter, at four to six weeks versus 10 to 12 weeks
- MMP is generally more affordable
What to Expect With MMP Treatment
When you entrust us with your pet’s care, Dr. Mears and the Indian Ridge Animal Hospital team will work with you to develop a treatment and therapy plan for your dog — both pre- and post-surgery.
This form of treatment works by redirecting the force generated by the large quadriceps muscles and compensating for the CCL failure. To achieve this result, Dr. Mears frees the part of the tibia attached to the muscle. Once cut, the tibia is shifted forward so that it’s at a 90-degree angle to the patellar tendon. This shift allows this band of tissue to take over for the CCL and perform its function.
The cut is stabilized using an advanced orthopedic implant material called OrthoFoam, which supports healing and accelerates bone growth. After four to six weeks, bone material and capillaries penetrate the porous titanium OrthoFoam enough to stabilize the CCL repair. This effect is the key to the minimal pain and reduced convalescence seen with MMP surgery.
MMP Recovery
Once your dog is ready to return home, our team will go over care instructions with you to optimize the healing process and reduce the risk of strain, stress fracture or implant failure. Your dog will need plenty of rest and a period of controlled physical activity as they recover from MMP surgery.
You will want to prevent running, jumping and rough play and block off access to stairs. We recommend walking your dog on a leash every time they’re outside for at least two weeks post-surgery to prevent reinjury.
Here is a timeline that will give you a better idea of the recovery process:
- After two days: Your dog should be able to put minimal weight on the affected leg while walking.
- After two weeks: Sutures are removed. You can now take your dog on slow leash walks no longer than 10 minutes up to eight times a day. You should notice your dog using their affected leg with each step.
- Within four weeks: Slowly increase your dog’s activity on the leash. You should also be able to take your dog on slightly longer walks.
- After six weeks: We will X-ray the patient to confirm that healing is proceeding according to plan. Continue to increase your dog’s activity, such as 30-minute walks in grassy areas. Your dog can go off-leash for five minutes if no other dogs are present.
- After 12 weeks: Your dog should be able to resume their pre-injury level of activity.
