After having one of the best rated surgeons on Long Island perform my knee surgery, I went two years with further pain, especially on walking up & downstairs. After complaining to my surgeon for 2 years, he told me that there was nothing more that he could do for me and that maybe I should see another doctor for consult. I finally visited Dr. King, who ordered special MRI exams and in turn referred me to Dr. Geoffrey Westrich, who immediately diagnosed my problem. He set me up to do a revision of my knee due to the fact that the original surgery omitted the resurfacing of the patella. Today I can walk up & down stairs, and have less pain each day. I can stand several hours at a time and even do a light jog for exercise.
