[|Human|] I have had a hard long type lump at the side of my left knee for about ten years nagging pain on and off I did not have any injury and I don t do any kind of sports was told by a doctor a few years ago it might be a cyst in the cartilage I never went back they could not see anything on the xray but the lump seems to be moving from were it was to the top right of my knee please help
[|AI|]  So the lump is painful, moving, hard, for many years but without any injury and not detectable with x-ray! That I could conclude from your description; anyway, thanks for your information shared on Chat Doctor! Could you please repeat your x-ray in some other lab in the mid-flexed position and a lateral view report is necessary in this case; because I think I is definitely a cystic lesion like bursa, ganglion or some loose bodies etc...benign definitely and not to worry!a recurrent patellar dislocation is another possibility. Therefore do the test and revert us; regards,
