Product Description
The spacers feature an open-cell structure that facilitates bone graft packing and rapid osteointegration, ensuring long-term stability of the osteotomy site.
Designed for multi-point anchorage in the tibial tuberosity, the forks provide superior pull-out resistance compared to standard screws in the thin cranial cortex.
All components are made from Ti-6Al-4V, offering maximum biocompatibility and corrosion resistance, minimizing the risk of "cold sensitivity" or implant rejection.
The tension-band plates are designed to be thin yet rigid, reducing the palpable presence of the hardware under the skin of the medial tibia.
While the TTA system is exclusively for the hind limb stifle joint, its principles of geometric realignment are foundational to veterinary orthopedic training across all joint procedures.
Indicated for dogs with CCL rupture who also suffer from mild hip dysplasia; by stabilizing the stifle, the system improves overall hind limb gait and reduces compensatory stress on the hip.
The primary indication. Specifically designed for dogs with a steep tibial plateau or chronic CCL tears, providing a biomechanical solution to stifle instability and "drawer" motion.
Can be adapted for the stabilization of tibial tuberosity avulsions in young, growing dogs, where the plate and fork system provides secure tension-band fixation.

The Veterinary TTA (Tibial Tuberosity Advancement) System is a specialized orthopedic implant set used to treat cranial cruciate ligament (CCL) rupture in dogs. Unlike procedures that attempt to replace the ligament, the TTA system modifies the internal geometry of the stifle joint. It consists of a Titanium cage that acts as a spacer, a tension-band plate, and a unique fixation fork. By advancing the tibial tuberosity forward, the patellar tendon is repositioned to a 90-degree angle relative to the tibial plateau. This mechanical shift neutralizes the shear forces (cranial tibial thrust) that occur when the dog walks, effectively stabilizing the knee without the need for an intact CCL.
The TTA system is primarily applied in medium to large breed dogs suffering from acute or chronic stifle instability. It is particularly effective for active dogs where a rapid return to function is required. The system is used to treat both partial and full ruptures of the CCL. Because the TTA procedure is less invasive to the joint capsule than some other osteotomy techniques, it is often favored for patients with significant pre-existing inflammation. Additionally, the TTA system is used in cases where the tibial plateau angle (TPA) is within a moderate range, providing a predictable and stable outcome for a wide variety of canine morphologies.
The primary advantage of the TOOLMED TTA system is its use of Titanium (Ti-6Al-4V), which offers superior biocompatibility and lower infection rates compared to stainless steel. The system’s porous cage design encourages rapid bony bridging, leading to faster healing times. Another significant benefit is the fixation fork; unlike screws, the fork distributes the load across a larger surface area of the bone, which is critical in preventing "tuberosity avulsion" or hardware pull-out. Furthermore, the TTA procedure is generally considered to have a shorter learning curve and shorter surgical time compared to Tibial Plateau Leveling Osteotomy (TPLO), while providing comparable clinical results.
Biomechanically, the TTA system works on the principle of force neutralization. In a CCL-deficient dog, the femoral condyles tend to slide backward on the sloped tibial plateau. By advancing the tibial tuberosity, the TTA system increases the tension in the patellar tendon and realigns it so that the total joint force is parallel to the patellar ligament. This 90-degree alignment ensures that whenever the quadriceps muscles contract, the force is directed into the bone rather than causing the tibia to slide forward. The cage maintains the advancement distance, while the plate and fork act as a tension band to resist the powerful pull of the quadriceps muscle.
The surgical technique begins with a medial approach to the tibia. An osteotomy is performed on the tibial tuberosity, and the distance for advancement is measured using a TTA template. The appropriate Titanium cage is inserted into the osteotomy gap. The TTA plate is then secured to the advanced tuberosity using the fixation fork, which is driven into the bone using a specialized fork inserter. Finally, the distal end of the plate is secured to the tibial shaft with cortical screws. Bone graft or bone substitute is typically packed into and around the cage to accelerate osteointegration. Proper alignment is verified through postoperative radiographs.
Postoperative care involves restricted activity (leash walks only) for 6-8 weeks to allow for bone healing across the cage. For the veterinary hospital, the maintenance of the TTA instrument set is critical. All fork inserters, cage spreaders, and drills must be cleaned and inspected for wear. Titanium implants are single-use only; they must never be re-bent or re-sterilized if they have been previously shaped. The entire TTA tray, including cages and plates, should be sterilized using a standard steam autoclave at 134°C. Regular follow-up X-rays at 4 and 8 weeks are necessary to monitor bone healing and ensure there is no hardware migration or tuberosity fracture.
The TOOLMED Veterinary TTA System provides a robust, biomechanically sound, and biocompatible solution for one of the most common orthopedic injuries in dogs. Its high-quality Titanium components and specialized fixation design ensure a stable, predictable recovery, helping canine patients return to an active, pain-free life.
The cage size is determined using preoperative radiographs and a TTA transparency template. You measure the distance required to bring the patellar tendon perpendicular to the tibial plateau; this measurement in millimeters corresponds to the cage width.
Yes, we offer mini-TTA components (3.0mm and 4.5mm cages) specifically designed for smaller breeds where standard hardware would be too large and bulky.
While the cage is designed to encourage ingrowth, packing the cage with autologous bone or a bone substitute is highly recommended to speed up the healing process and ensure a solid bony union.
The fork is intended for permanent implantation. However, if removal is clinically necessary (e.g., due to infection), it can be extracted using a specialized fork puller included in the TOOLMED instrument set.
Titanium provides better osteointegration with the cage and is less likely to cause the "stress shielding" effect, which helps maintain the bone density of the advanced tibial tuberosity.
