I went to see Dr. DiFelice after having my activities slowed to a halt. He said I was on the cusp of a full knee replacement. After evaluating me, he decided to go ahead with a partial replacement I placed my trust in the expertise and judgment of Dr. DiFelice and have never regretted it. After a short recovery I have lived the past year pain free. I will always be grateful to Dr. DiFelice and the wonderful care I received while at HSS.
