Osteoarthritis is widespread and costly – both to individuals and to the nation.

There is limited osteoarthritis (OA)-specific cost data and the majority of cost estimates reflect the total cost of all forms of arthritis.  However, OA, which affects an estimated 32.8 million adults, is the most common form of the more than 100 different rheumatic conditions that comprise arthritis.2  The number of adults with OA is expected to increase as baby boomers age, because older adults have a higher prevalence of arthritis and OA.3  By 2040, the number of adults with arthritis is projected to increase to 78.4 million, most of whom will have OA.3  It is estimated that two-thirds of adults with obesity will develop knee OA at some point in their life, so rates of OA will increase with the obesity epidemic.15

How the Cost of OA Affects the Nation

OA has a significant economic impact due to the effects of disability, comorbid disease, and the expense of treatment.4 

Economic Impact

The United States Bone and Joint Initiative (USBJI) highlights the enormous economic impact of OA in their Burden of Musculoskeletal Diseases5 report:

  • 33% of reported lost work days for medical conditions was due to arthritis-related conditions (172.1 million total work days lost).
  • Mean health care expenditures for arthritis-related conditions increased 192% from 1996 to 2011. For those with OA, per-person medical costs attributed to OA averaged $2,017 per-year between 2008 to 2011.
  • In 2010, there were 21.7 million ambulatory care visits and over 6.7 million inpatient hospitalizations for people with OA.
  • In 2010 and 2011, there were an estimated 1.3 to 1.4 million joint replacements performed, the majority for people with OA.
  • Despite a decline in length of hospital stay (mean of 9 days in 1992 to 3.5 days in 2010), USBJI reports that “total hospitalization charges for both knee replacements have more than quadrupled (in constant 2011 dollars) from $8.1 billion in 1998 to $38.5 billion in 2011.”
  • Medical expenditures attributed to OA averaged $62.1 billion nationally in each year between 2008 and 2011.

Social Impact

  • OA disproportionately affects women and minorities. More women than men have OA, particularly after age 50. Documented disparities include significantly greater adverse effects (activity limitation, work limitation, and severe pain) due to OA among African American compared to non-Hispanic white populations, despite equivalent OA prevalence between the two groups. Of increased concern, African Americans receive 39% fewer total knee replacements than whites despite similar levels of severe OA.16

How the Cost of Arthritis Affects the States

When broken down by state, information from 2003 shows total costs of arthritis ranged from $226 million in the District of Columbia to $12.1 billion in California.6

The states with the highest cost attributable to arthritis:

  1. California, $12.1 billion
  2. New York, $8.7 billion
  3. Texas, $8.7 billion
  4. Florida, $7.6 billion
  5. Pennsylvania, $6.5 billion
  6. Ohio, $5.7 billion
  7. Michigan, $5.5 billion
  8. North Carolina, $4.1 billion
  9. Georgia, $3.9 billion
  10. New Jersey, $3.5 billion

How the Cost of OA Affects the Employer

While OA is more common among employees in certain occupations such as mining, construction, agriculture, and sectors of the service industry, OA can interfere with the ability to be productive while on any job.7,8

  • Between 2010 and 2012, 3.8 million adults in the US with doctor-diagnosed arthritis reported they were unable to work due to their health, and 2.1 million adults reported they were limited in the kind or amount of work they could do.5  As the most common form of arthritis, it is likely that OA accounts for a large portion of those with work limitations.
  • Total national arthritis-attributable lost wages were $164 billion in 2013.6  That amounts to $4,040 less pay for an adult with arthritis compared with an adult without arthritis.15  
  • OA severely limits productivity. Approximately 30% of adults age 18 to 64y with doctor-diagnosed arthritis report an arthritis-attributable work limitation,including working less or not working at all. Much of this is due to OA.
