I'm a Surgical Technologist - or I was. I fell last May(2006) in the operating room onto my right knee - but in 'seated' jobs(wherevever the hospital wants to put me) and in January had a knee scope - have Patella Chondromalacia - Grade III - my OS talking about a possible Faulkerson's Procedure or Patella Femoral Joint Replacement. I haven't worked since 1/19/07. Don't know if I'm going to be able to do my job again. So that's why I say 'or I was'.
