I need some help understanding my MRI results of my knee?

The medial condyle of the knee is more prone to osteoarthritic changes than the lateral. So the finding is not surprising. It simply means that you have early arthritic changes in your knee, perhaps this is a knee that you injured in your life and this is accelerating the degeneration. The edema could be caused by a trauma. There isn't much you can to but to take care of your knees. You would not be a good candidate to play basketball.
