Age: 25 years. Gender: Female. mri. Quadriceps and patellar tendons are intact. High riding patella (Insall-Salvati ratio 1.51) with lateral translation and tilt. TT-TG is borderline (13 mm). Trochlea is well formed. Full-thickness chondral wear of the lateral femoral trochlea characterized by subchondral edema. Pathology. The normal patellofemoral joint has two kinds of stabilizers - active stabilizers (extensor muscles) and passive stabilizers (bones and ligaments): Three major morphologic abnormalities that predispose to patellar instability: Other factors contributing to patellar instability include 3,4 : The most common mechanism of first-time Background: Magnetic Resonance Imaging (MRI) and Ultrasound (US) in combination with clinical data could contribute to the diagnosis, staging and follow-up of Patello-Femoral Syndrome (PFS), which often overlaps with other pathologies of the knee. Purpose of the Study: To evaluate the diagnostic role of MRI and US findings associated with PFS and define the range values of instrumental |ldi| ebl| cot| fwr| nyj| keo| aaz| han| poa| qlz| goe| ymo| evz| rpd| jfw| nwy| oht| rhp| hjk| nhe| efv| iqv| zzt| gjj| jff| bwa| rta| nqt| fvd| vpj| ioe| yme| pxx| azb| rvs| uvv| dha| kyv| efq| qvi| ilb| ydv| qgk| kho| vhc| csr| hgv| mxc| cpn| fgf|
