Knee pain is one of the most common complaints that I see in my line of work. Unfortunately, as obesity rates around the world continue to rise, knee replacement surgeries are increasing at an alarmingly high rate.

Presentation / Chief Complaint - A 45 year old male patient presents in April, 2007 with bilateral knee pain, stiffness, and right greater than left knee edema aggravated by climbing stairs and walking. Status became acutely severe whenever walking up more than one half a flight of stairs, or one half of a city block.
