Gregory Ancona, a patient of Dr. Daniel W. Green at the Hospital for Special Surgery

Gregory Ancona’s story, in their own words

After meeting with Dr. Green we decided I needed surgery. I had knee surgery in April 2019 to treat the osteochondritis dissecans in my left knee. Thanks to Dr. Green and the staff at HSS, I was back playing middle school soccer five months after surgery.
