Dr. Bose, firstly I want to thank you again for the "miracle" of the new knees. After the initial recovery I have been Pain free. Before it was a struggle to walk one block, and tennis was becoming more difficult and increasing painful (a constant 7). Now I can walk comfortably for any reasonable distance, and have become a "butterfly on the court".
Mrs Al Saeed Nada Ali Kadhim, from Iraq had
Rheumatoid arthritis on both her knees for 20 years.
