I climbed stairs, hiked around, walked several miles each day and carried my 40lbs pack around Vietnam. Johnny and I were very please with my new mobility. Johnny kept asking me throughout our trip “how’s you knee……how’s you knee” and each time I would say its doing great! Throughout our trip, we keep praising you guys and saying how grateful we were to have found such great doctors. So….thank you guys again for giving me a new lease on life!!!!!
