The Oss|Ability Tibial Tuberosity Advancement (TTA) Wedge System reduces the learning curve for new surgeons and helps the experienced surgeon achieve repeatable results in less time.
How does the Oss|Ability TTA Wedge System stand out?
Most veterinary saw and drill guides rely on the experience and subjective decision making by the surgeon. The Oss|Ability guide instead controls the final tibial tuberosity thickness as well as osteotomy length, obliquity and termination position, and is configured prior to surgical incision. This means the surgeon knows the result they are going to get before they begin the procedure.
Clever Integration Between Preoperative Planning and the Osteotomy Guide
Proper planning and implant selection are critical to a successful treatment. With the Oss|Ability TTA Wedge System the surgeon can select not only the advancement and corresponding implant required, but where the osteotomy should be positioned to maintain the integrity of the tibia. These settings are easily dialled into the guide and the surgeon can have confidence that the osteotomy will end up in the right place. There are no surprises on the postoperative radiographs.
Advanced Implant Technology
The Oss|Ability Wedge Implant is a 3D printed titanium implant with a proprietary porous structure that promotes bone ingrowth. The scaffold implant is around 70% porous with a pore size greater than 600 μm and mimics the properties of trabecular bone. The combination of implant design and porous structure means that bone grafting is not required. The implant has a very high coefficient of friction that secures it in place initially and this is followed by rapid osseointegration for long term stability.
The Final Mechanical Construct
The Oss|Ability TTA Wedge System is a robust mechanical construct based on tried and true principles. The procedure is based on the Modified Maquet Technique (MMT) and maintains a bone hinge on the tuberosity. The Oss|Ability procedure then adds additional support to that bone hinge with a tension band plate so that the final construct is constrained in tension, rotation and bending planes. This construct also acts to support the tibia against diaphysial fracture. The final construct of an opening wedge implant and plate act together to compress the osteotomy and speed up bone healing.
Research & Clinical Outcomes
Oss|Ability provides an opportunity for veterinarians to contribute their experience and outcomes data for publication. The data is analysed as the cases are submitted, giving an accurate and up-to-date picture of how patients are progressing. This data also allows us to improve the system further through incremental updates. Oss|Ability is also involved in comparative clinical research that evaluates cruciate disease treatments with independent surgeons.
The Oss|Ability TTA Wedge System provides a simple, fast and stress-free way of treating lameness secondary to canine cruciate ligament disease and draws on the latest advancements in medical 3D printing technology.
