Outcome of surgery for recurrent patellar dislocation based on the distance of the tibial tuberosity to the trochlear groove.
We evaluated the outcome in a series of patients with recurrent patellar dislocation who had either medial transfer of the tibial tuberosity and lateral release or an isolated lateral release as the primary treatment. The decision to use one or other procedure was based on a pre-operative distance between the tibial tuberosity to the trochlear groove (TTTG) of less than 10 mm to include the tib...
متن کاملTibial tubercle to trochlear groove distance and index in children with one-time versus recurrent patellar dislocation: a magnetic resonance imaging study.
PURPOSE To compare the tibial tubercle to trochlear groove (TT-TG) distance and index using magnetic resonance imaging (MRI) between children with onetime and recurrent patellar dislocation. METHODS Records of first-time acute patellar dislocations from 2007 to 2012 were reviewed. 20 males and 23 females aged 10 to 17 years at presentation were included for measurements of the bony and cartil...
متن کاملPatellar Tendon–Trochlear Groove Angle Measurement
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...
متن کاملPatellar instability.
Recurrent patellar instability can result from osseous abnormalities, such as patella alta, a distance of >20 mm between the tibial tubercle and the trochlear groove, and trochlear dysplasia, or it can result from soft-tissue abnormalities, such as a torn medial patellofemoral ligament or a weakened vastus medialis obliquus. Nonoperative treatment includes physical therapy, focusing on strength...
متن کاملUse of computed tomography to determine the risk of patellar dislocation in 921 patients with patellar instability
The purpose of this research was to identify reliable tomographic measurements that can detect patellofemoral abnormality and allow quantification of the risk of patellar dislocation in patients with potential patellar instability. A cross-sectional study in 921 patients with anterior pain or knee instability of at least 6 months' duration was conducted from July 2001 to December 2009. All subj...
