Tibial Diaphyseal Fracture Rates Following Tibial Tuberosity Advancement Rapid (TTAR) and Traditional Tibial Tuberosity Advancement (tTTA)

Tibial tuberosity advancement in 65 canine stifles.

The tibial tuberosity advancement (TTA) procedure was developed to treat dogs with cranial cruciate ligament deficient stifles. A retrospective, descriptive study was performed on 57 dogs that underwent unilateral or bilateral TTA. Medical records were reviewed and pre-, postoperative and follow-up radiographs were evaluated for patellar ligament-tibial plateau angle (alpha), distance of the ti...

Tibial Tuberosity Advancement (tta) for Cranial Cruciate Ligament Disease

Advancement of the tibial tuberosity. A biomechanical study.

The effects of advancement of the tibial tuberosity by inserting bony wedges was studied on cadaveric specimens of the knee. The geometry, the contact areas and the forces acting on the patellofemoral joint were investigated, and the forces acting on the tibiofemoral compartment were calculated. A 1 cm advancement was found to be optimal in reducing the high patellofemoral joint forces occurrin...

Effect of proximal translation of the osteotomized tibial tuberosity during tibial tuberosity advancement on patellar position and patellar ligament angle

BACKGROUND Cranial cruciate ligament insufficiency is a common orthopaedic problem in canine patients. This cadaveric and radiographic study was performed with the aim of determining the effect of proximal translation of the tibial tuberosity during tibial tuberosity advancement (TTA) on patellar position (PP) and patellar ligament angle (PLA). RESULTS Disarticulated left hind limb specimens ...

Genu Recurvatum after Tibial Tuberosity Fracture

Fractures of the tibial tuberosity are infrequent injuries that occur during adolescence. Displaced tibial tuberosity fractures are typically treated with open reduction and internal fixation. Since these fractures occur at or near skeletal maturity, growth disturbances are not seen. This paper presents a case, the first report to our knowledge, of genu recurvatum deformity after open reduction...
