For years, my right knee was increasingly painful. I could not walk a block comfortably, I limped, my leg would not straighten. I was so hampered that I contemplated giving up my daily yoga and Pilates classes. I tried all of the exercises, all of the injections, but nothing relieved the severe arthritis. My heart in my throat, I scheduled the surgery with Dr. Su. I cannot believe the difference. Three nights at HSS, five at Burke, and I was walking without a cane. I drove on day 17 and it was my right knee. I can walk for miles, resumed all of my exercise, and last week walked six miles with my daughter in the California hills, all with no pain whatsoever. I am so grateful to Dr. Su and the HSS staff.
