The purpose of this study was to investigate the influence of running on patellar water content and bone marrow edema (BME) in individuals with and without patellofemoral pain (PFP). Using the IDEAL protocol, two subjects with PFP and 2 pain-free controls were evaluated. Each subject underwent a pre-running MR scan, a 40-min moderate effort running, and a post-running MR scan. Our data showed that in persons with PFP, content and volume of local BME increases post-running. Additionally, the PFP subjects demonstrated increased water content of the bone marrow region post-running while the controls showed no changes in water content.
