I started having knee pain in my 20's. Lived with it for 20 years before I had enough of the pain and made an appointment with Dr. Gonzalez Della Valle. Made the decision to have the surgery and it was the best decision I ever made. Changed my life. 7 years later and still no pain. The recovery was tough but so worth it. I mountain bike a few times a week and have no problems. HSS and Dr. Gonzalez Della Valle were awesome.
