PET DEGREE Hospital is proud to be Western New York’s cost effective orthopedic surgery, pain management, and rehabilitation center.

Cranial Cruciate Ligament (CCL) rupture, similar to Anterior Cruciate Ligament (ACL) rupture in people, is the most common orthopedic problem in dogs.  Surgical correction of this CCL disease is critical to prevent degenerative disease of the dog’s joint.  Through the years there have been many surgical techniques for stabilization and each patient should be fully evaluated before any surgery is considered.  Rehabilitation is critical for surgical as well as non-surgical patients to return to function.  When surgery is necessary it is important to consider the most current repair techniques of TPLO and TTA which utilize geometric modification of the bones for stabilization.  Both methods are superior in correcting joint bio-mechanics, however, TTA has been shown to less risk for complications.

TTA Rapid (Tibial Tuberosity Advancement Rapid) for treatment of cranial cruciate ligament injuries in dogs.

The dog TTA Rapid technique combines the best features of several previous tibial levelling procedures, including TTO (Triple Tibial Osteotomy), MMT (Modified Maquet Technique) and MMP (Modified Maquet Procedure). The principle behind each of these techniques is to eliminate cranial tibial thrust by advancing the tibial tuberosity a specific distance, so that the straight patellar ligament is at right angles to the tibial plateau. (The tibial tuberosity is the point of insertion of the straight patellar ligament). The straight patellar ligament therefore acts to stabilize cranial tibial thrust.

Advantages of the dog TTA Rapid technique

  • Relatively non-invasive soft tissue approach, to the craniomedial tibia. This allows rapid healing and minimizes post-operative discomfort.
  • Robust tibial tuberosity advancement utilising a low profile titanium cage, anchored by either 4 or 6 titanium screws depending on patient size.
  • Titanium is extremely strong, light and is the most biocompatible implant material available at the present time. The titanium cage has pores with a ‘’honey comb’’ structure, which allows ingrowth of tibial bone into the cage, maximising tibial tuberosity strength. This minimises the risk of implant loosening, rejection and infection.
  • A hydroxyapatite bone graft is placed in the pores of the cage and the osteotomy site to maximise the speed of TTA Rapid healing. (Radiographic evidence of bone healing is fairly advanced after 6 weeks).

Breeds most affected:

Labrador, Border Collie, Dalmatian, Staffordshire Bull Terrier, Bulldog,  Golden Retriever ,  Mastiff,  Boxer, Newfoundland, Rottweiler, Labradoodle, Akita, Springer Spaniel, English Bull terrier, and many mixed breed.


  • Transient skin irritation. Patients required a short course of antibiotics after licking the incision line following dressing removal at 5 days post op.
  • Late meniscal cartilage tears. In cases the owners had failed to confine their dogs to strict lead exercise in the post-operative period (3 months on short lead, then 1 month on extendable lead with controlled trotting). These cases went on to make excellent recoveries following partial meniscectomy.
  • We have been very pleased with the results of cases treated by TTA Rapid cruciate ligament surgery. We are more than happy to continue to provide TTA Rapid procedures to referring practices. In the few cases where complications occurred, a problem was identified arising in the post-operative period when the patient was at home in the care of the owners (either licking the incision line or over-activity whilst off lead). As with any orthopedic surgical procedure, strict adherence to the clear, written post-operative instructions which we provide is essential. (Strict lead exercise and prevent licking in the post-operative period).

Our pricing structure is “middle tier”, aiming to offer a value for money referral service. We always try to give accurate written estimates to clients in advance, on a no-obligation basis. Our pricing structure can often offer significant savings to clients, when compared to quotes for equivalent conditions and procedures in the larger referral centers. We try to avoid very expensive “major plus” surgical interventions unless these are absolutely necessary. Many owners do not have pet health insurance for their animals. In the interests of animal welfare, we always try to offer an ethical, good quality and cost-effective orthopaedic service at very competitive fee levels.
