Personal factors linked with increased risk of knee OA in the military population

In an active military population, the incidence of primary and secondary knee osteoarthritis correlated with chronological age, race, rank and branch of service, according to results.

Using the Defense Medical Epidemiology Database, researchers performed a retrospective review of 21,318 cases of osteoarthritis (OA) of the knee among U.S. military, active-duty service members between 2005 and 2014. There were 19,504 cases of primary OA and 1,814 cases of secondary OA.

Results showed an increase in the adjusted incidence rates by 45% in primary OA from 0.51 in 2005 to 0.74 in 2014, and by 100% in secondary OA from 0.03 in 2005 to 0.06 in 2014. Researchers noted increasing age was a significant risk factor for primary and secondary OA.

The Frequency, Severity, and Economic Consequences of Musculoskeletal Injuries to Firefighters. The most common work-related injuries among firefighters are musculoskeletal disorders (MSDs). The strict physical demands of the job and limited modified work opportunities suggest that MSDs are potentially more disruptive and costly to firefighters than to others. Rand Corporation

While the risk of OA increased among women aged 35 years to 39 years, according to results, incidence rate ratios decreased among women service members in the age groups younger than 20 years; 20 years to 24 years; and 25 years to 29 years. An increased risk for knee OA was also associated with black race, senior military rank and Army, Marines and Air Force services, researchers found.
