Prevalence of Radiographic and Magnetic Resonance Imaging Features of Patellofemoral Osteoarthritis in Young and Middle-Aged Adults With Persistent Patellofemoral Pain.
To describe the prevalence of radiographic features of patellofemoral (PF) osteoarthritis (OA) in adults with persistent PF pain, to describe the prevalence of magnetic resonance imaging (MRI)-defined PF OA and compare it to that in age- and sex-matched controls, and to explore the prevalence of radiographic and MRI-defined PF OA across age, sex, and body mass index (BMI) groups. ⋯ Features of radiographic and MRI-defined PF OA were evident in 20-30% of adults ages 26-50 years with persistent PF pain, with greater prevalence observed in those who were older, or female, or who had a higher BMI. MRI-defined PF OA was more prevalent in individuals with PF pain than in pain-free controls, especially when defined as a full-thickness cartilage lesion with BML.
