My 13 year old son has a bubble feeling in his knee. An MRI showed inflamed fluid and a bubble in the upper right part of his knee just below the knee cap. Our ortho doctor said it is a villonodular synovius (sp?). I was reading about the VS and what I read said it can lead to arthritis. Even in a 13 year old boy?
Welcome to Chat Doctor I have gone through your query and understand your concern. Yes you are correct it can lead to early osteoarthritis. Treatment of it is biopsy to confirm it. After confirmation your doctor can excise(removal of synovial) it. But it is said to reoccur in half the cases. Radiation therapy is useful to present recurrence. You can discuss with your doctor about it. Hope your query get answered. If you have any clarification then don't hesitate to write to us. I will be happy to help you. Wishing you a good health. Take care.
