Medical Study Reveals Knee Replacement Surgery Has Physical As Well As Financial Benefits

An Active Labor Day Weekend Reminds Many of Your Viewers About Their “Bad Knees”

The Good News? More Than 600,000 Knee Replacements Annually; Lifetime Benefit Averages $10,000-$30,000 Per Patient

Rosemont, Ill. – Researchers have found the benefits for working-age knee replacement patients far outweigh the actual cost of the surgery and rehabilitation, compared to non-surgical treatments for osteoarthritis of the knee. The direct costs for knee replacement surgery and rehabilitation of a Medicare patient averaged $20,704 with those costs offset by an average indirect savings of $39,697. The end result is a lifetime net benefit ranging from $10,000 - $30,000 per patient – not to mention keeping those patients active and employed.

The new study published this month in the Journal of Bone and Joint Surgery (JBJS) demonstrates the importance of maintaining access to knee replacement surgery for those suffering from osteoarthritis.

“Most of the societal savings come from the patient’s ability to maintain employment and increase earnings over a longer time in the workforce. We also found benefits from fewer missed worked days and lower disability payments,” said study author and health care economist Lane Koenig, Ph.D. “This methodology application has opened the door for a broader set of health care services to be evaluated using a societal perspective, which is truly exciting.”

More than 90 percent of people who have total knee replacement surgery experience a dramatic reduction of knee pain and a significant improvement in the ability to perform common activities of daily living, allowing them to return to work and tremendously enhance their quality of life . The study, “The Direct and Indirect Costs to Society of Treatment for End-Stage Knee Osteoarthritis,” shows how knee replacement surgery can be a valuable and cost-effective treatment for patients with end-stage osteoarthritis, estimating lifetime societal savings of about $12 billion from the more than 600,000 total knee replacement surgeries performed in the U.S. in 2009.

“The demographic profile of a knee replacement patient is changing,” said John R. Tongue, MD, American Academy of Orthopaedic Surgeons (AAOS) past-president. “Half the patients getting knee replacements now are younger than 65 years of age and most of them are still in the workforce.”

There is a desire among the aging population to stay active and remain in the workforce. The combination of the aging population and the rising epidemic of obesity can lead to an increasing demand for joint replacement. The demand for total knee replacement is expected to exceed 3 million by the year 2030 according to the Agency for Healthcare Research and Quality.

Dr. Tongue added, “We know that when a knee replacement is done on patients at the appropriate time, it adds tremendous value to their lives. It gets them back to work and back to their families. It improves their quality of life and allows them to be productive and active again. But until now, that value has been hard to quantify. This study allows patients to see the big picture effect on their daily lives and in the long term.”

To conduct the study, researchers reviewed literature and Medicare claims data. The collected data were applied to a Markov Decision Model which they used to estimate the total societal savings. This new methodological model, published this year in Cost Effectiveness and Resource Allocation, allowed researchers to calculate indirect economic and societal impacts for orthopaedic procedures. This methodology was then applied to the economic impact of total knee replacements.

The full JBJS study “The Direct and Indirect Costs to Society of Treatment for End-Stage Knee Osteoarthritis,” identifying a quantifiable view of the value of knee replacement surgery compares costs for direct medical care, long-term medical care, home modification and long-term nursing home use for both surgical and non-surgical treatments among patients age 65 and older.

AAOS commissioned KNG Health Consulting, LLC and its partner, IHS Global Inc., to prepare this study.
