What factors have influenced the rise in knee replacements?
Interview: Peter Cram, M.D., M.B.A., Director, Division of General Medicine, University of Iowa Carver College of Medicine.
Total knee replacement has become one of the most common and most expensive surgeries in the U.S. Peter Cram, M.D., MBA, director of the Division of General Medicine at the University of Iowa Carver College of Medicine, ascribes the growth in knee replacements to the desire of older Americans to remain active and Medicare’s generous coverage of the procedure. Another factor: Artificial knee replacements last 10 to 20 years, which may necessitate an additional replacement during a patient’s lifetime. Cram says the growth in knee replacements cannot be attributed to increased levels of obesity.
