Abstract

Patellar instability is a complex problem that requires a thorough evaluation and work up. A critical part of this work up is appropriate imaging. This article reviews key imaging techniques and important imaging findings in patellar instability patients. This includes the evaluation of patella alta, trochlear dysplasia, lateral patellar tilt, extensor mechanism alignment, valgus alignment, rotational alignment, and soft tissue injury. Effective management for patellar instability relies on a comprehensive approach where any of these elements are evaluated when necessary.
Keywords: Patellofemoral Instability, Patellar Instability, Patellar Dislocation, Imaging.
