Doctor: HelloThank you for posting your query on ATD.I have gone through your query and understand your concern. I think i t is nothing abnormal. As it appear only on extension of knee, it seems to me a normal variation of bone as it is not causing pain. However, you are advised x-ray to rule out any pathology. Hope your query get answered.Wishing you a good health.Take care.
