I had something similar..
My knee would be swolen for a month or two.. I noticed a great deal of stiffness.. sometimes my knee would pop while walking,standing.. I would fall and or start to trip alot... then one day I fell so hard and landed on the knee that was giving me the trouble and my employer sent me to the doctor. Test were ran and it was determined that I had a large benign tumor under my knee cap. The medical term for what my condition is, is PVNS (short) or Pigmented Villonodular Synovitis(long). There is a bunch of information out there to read which might be very helpful.
Does your father have any of the symptoms that I mentioned?
