Background Genu valgum usually originates from a deformity of distal femur that is often corrected by distal femoral varus osteotomy. The osteotomy includes both components of angulationcorrection and translation because the site of osteotomy is not commonly at the apex of deformity. Improvement of patellar tracking not only depends on valgus correction, but also it may be partially due to cent...

Osgood-schlatter disease, non-articular osteochondrosis, is characterized by pain of anterior tibial tuberosity (TTA), which mainly affects the growing adolescent sportsman. It corresponds to "chronic lesions, due to microtrauma of repeated tractions on the area of insertion of the patellar tendon at the level of the anterior tibial tuberosity". This condition remains benign if the young patien...

Methods: Three PT-TG angle measurements and the PT-TG distance were measured in 82 participants with patellar instability and 100 controls using magnetic resonance imaging (MRI). Measurement landmarks were the line tangent to the posterior femoral condyles, the deepest point of the trochlea, the transepicondylar line, and the patellar tendon center. All measurements were recorded once by 1 exam...

Abstract Background The radiological indicators can help doctors determine whether to make tibial tubercle transfer. But which indicator is better still in question. Methods 117 knees 103 patients who had undergone patellar surgery and 60 58 no history of dislocation from 2014 2019 were analyzed. Significant differences tubercle–trochlear groove (TT-TG) on CT tubercle–posterior cruciate ligamen...

Methods 12 fresh frozen cadaver foot and ankle specimens were used. The peroneal longus and brevis tendons, as well as the posterior tibial tendon, were identified and tagged. A flexible thin computerized pressure sensor strip (Tekscan), containing 4 sensor pads, was placed longitudinally within the groove between the peroneus brevis tendon and posterior fibula. These 4 sensor pads were separat...

Background Although tensile force on an immature tibial tuberosity is considered the main cause of Osgood-Schlatter disease (OSD), the relationship between bony maturity and the pathogenesis of OSD remains obscure. Purpose To survey the bone maturation process of the tibial tuberosity by age and sex and clarify its relationship to OSD. Study Design Cross-sectional study; Level of evidence, ...

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...
