Do I have Osteochondrtis Dissecans

Patient: My leg does not hurt whatsoever but a piece of my bone came loose and is floating far away from where it came off in my knee. I got an MRI done one day ago but the doctor has not called me back. Do I have OCD?

Symptoms: Small Bone Lump at top of my knee, came from bottom of knee, absolutely no pain

Doctor: Thank you for writing to us.OCD is a disease in which articular cartilage has cracks in it. It is the cartilage whic h has damage in it. Without even seeing the MRI, I cannot decide if you have OCD or not.Please rewrite the question and send it to us again. We are here to help you.
