Comments: I am close to 4 months out now and my new knee is awesome. After 9 Weeks from the date of the surgery, I hiked up the Grand Canyon's Bright Angel Trail from the rivers edge. This was an 8 mile hike with 4,000 feet elevation up, just up. My knee not only survived, it thrived. I could not have made it on my old knee. Whatever Dr. Delos did, he did it perfectly. I could not be happier with the whole process. Juliet, the surgical coordinator, was equally as awesome. All that I can say is Thank You!
