CT Analysis of the Patellofemoral Joint in Patients Having Knee Surgery (PF)

September 12, 2019 updated by: John Marzo, State University of New York at Buffalo

Comparison of a Novel Weight Bearing Cone Beam Computed Tomography (CT)Scanner Versus a Conventional CT Scanner for Measuring Patellar Instability

The primary hypothesis is that measures of patellofemoral alignment obtained from the investigational cone beam CT scanner will be reduced, but still correlated to those obtained from the conventional CT scan.
