Dr. MacGillivray performed ACL reconstruction surgery on my right knee. He also repaired a torn meniscus. Nine months after surgery I ran my best 10k. Within twelve months I was back to adventure races, golf, tennis and cycling. Since then, I've completed a 50 mile ultra and ran by best time in the NYC Marathon. Thanks to Dr. MacGillivray, my knee is stronger than ever as is my confidence to tackle the next challenge. Thanks Dr. MacGillivray and thanks HSS!
