“I'm sitting at my computer on a glorious sunny October afternoon having just returned from a three-mile hike in the Santa Monica mountains with my husband and our dog. This wouldn't be unusual except for the fact that just six weeks ago you replaced my left knee!”

— Celia on her total knee replacement

“Since you replaced both of my hips five years ago, I’ve been able to enjoy experiences that would have been difficult if not impossible for me: Traveling on an unforgettable trip to Italy and Germany; taking long walks on the beach in my neighborhood and shooting hoops in the backyard.”

“Not being able to put on my right sock, walk up stairs or hills, carry my grandchildren, and play golf and tennis had caused me to have a sedentary, unhealthy lifestyle. My surgery and post experience are 100% of my hopes, I now feel again that I am younger than my 65 years..”

— Robert on his total hip replacement
