"Over the past 25 years, thousands of clinical research publications have confirmed the effectiveness of arthroscopic knee surgery in reliving knee pain for millions of Americans.
"Osteoarthritis of the knee constitutes only a small segment of those who have arthroscopic knee surgery, and for the much larger group with torn cartilage and ligaments, arthroscopic surgery remains effective, less invasive and more cost-effective treatment than was available during its advent." The letter was signed by Vernon T. Tolo, MD, president of AAOS, and Peter Fowler, MD, president of the American Orthopaedic Society for Sports Medicine.
