Ellie was in an accident that left her with an artificial knee. Her other knee is still natural and very important to her, but 30 years ago, that knee was injured in a car accident, and she had to have arthroscopy on it at that time. Now, 30 years later, her natural knee has deteriorated. Her orthopedist told her that she is not a candidate for partial knee replacement, that she has to have full knee replacement on that knee. Ellie came to Rowen. She was skeptical of ozone, but she wanted to try it. She was quite surprised that the first ozone injection resulted in her knee pain going away. She is very happy.
