Abstract

PURPOSE
This study aims to evaluate magnetic resonance imaging (MRI) findings in young adults with symptomatic Osgood-Schlatter disease (OSD) and compare those in young adults without OSD.
MATERIALS AND METHODS
We compared MRI findings between young adults with OSD (OS group, n=30) and the equivalent number of young adults without OSD (control group). Visual analog scale scores and Kujala scores were evaluated and correlation analysis was performed in the OS group.
RESULTS
In the OS group, MRI revealed that the patellar tendon was attached to the tibia more widely, resulting in a reduced free tendon portion, and more proximally to the articular surface (p<0.001). The correlation analysis between MRI findings and clinical scores showed statistically significant correlations (p<0.01). In the OS group, 43% presented with patellar tendinopathy or bone marrow edema at the distal attachments.
CONCLUSIONS
Compared to the control group, the relatively small free portion and relatively proximal attachment of the patellar tendon were observed with MRI in the OS group. The free portion of the patellar tendon was positively correlated with the clinical scores. Patellar tendinopathy was also frequently encountered in the OS group.
