Osteochondrolesion???

I had an MRI done on my elbow. I have pitched for a few years and was alerted that I had an osteochondrolesion and also tendonitis… I was wondering what an osteochondrolesion is and what the treatment is. I was also wondering if tendonitis, commonly known as tennis elbow, was curable and what is needed to fix it.

Any help would be greatly appreciated…

THANKS!!!
