Basketball players place high loads on their knee joints that can lead to chronic knee injuries. In this study, we used advanced MRI methods and a cluster analysis to longitudinally study cartilage structure and potential early degenerative changes in Division 1 (D1) basketball players and swimmers. Pre-season and post-season quantitative results indicate an increase in T2 and T1p relaxation times in the central compartment of the femoral cartilage in the basketball players compared to the swimmers. The results of this study suggest that microstructural changes in knee cartilage can occur in one season of D1 college play.
