TROCA 56

A mongrel dog was presented with grade IV medial patellar luxation in the left hind limb along with torsional limb deformity, a severe condition causing significant lameness, instability, and pain. In this case, correcting the trochlear groove alone was not enough - the femur and the tibia also required corrective alignment to restore proper joint mechanics.

To support the surgeon in this complex procedure, LimesVet was asked to deliver a solution that combined accurate correction with reliable implant placement.

Using advanced 3D planning and patient-specific design, we created and 3D printed a custom surgical guide. This guide enabled precise femoral angular correction and helped define the exact positioning of the TROCA patellar groove prosthesis during surgery. In combination with the guide, the veterinarian used the TROCA 56 implant to restore proper trochlear surface and patellar route, and afterwards corrected the placement of the tibial tuberosity.

A key advantage of the TROCA system is that it does not require trochlear osteotomy of the patellar groove, while still fully matching the patient’s individual anatomy, and adjusting proper trochlear ridge heights. This allows for a less invasive approach, precise fit, and predictable biomechanical alignment.

This integrated solution reduced intraoperative uncertainty, increased surgical confidence, and resulted in a more stable stifle joint and a smoother recovery for the patient.

Cases like this demonstrate how personalized 3D-printed surgical guides combined with anatomy-matching implant systems can elevate complex orthopedic procedures - delivering greater safety for the veterinarian and better outcomes for the patient.
