The prevalence of cartilage lesions is much higher in athletes like football players than the general population. This pilot study is to determine whether dGEMRIC can be used to assess potential differences in cartilage GAG concentration due to the cumulative effects of playing college level football. It demonstrates that dGEMRIC is capable of evaluating GAG content in different regions as well as the apparent differences related to cumulative years of playing football.
