Had debilitating knee pain. Knee had bad arthritis and no meniscus. As a result, I couldn't train. I practice karate, Iaido, and weight training. With the knee pain and limited mobility, my activity was extremely limited. Since my total knee replacement, I am back to training and feeling like I'm 30 again. Best decision I ever made. HSS was the best place to get it done. Dr. DiFelice is fabulous. He is a great surgeon and very personable. He was responsive to all my concerns. Made it an easy decision.
