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.
