Serious knee injuries are on the decline in the National Football League, according to an injury reporting service provided by Durham-based technology company Quintiles.
The ACL injuries – short for anterior cruciate ligament – are closely monitored because some expected them to increase after the NFL banned hits to the head and neck area.
But the Quintiles Outcome service reported 30 ACL injuries through the first 13 weeks of the season. That’s down from 39 last year, 35 in 2011, 37 in 2010 and 31 in 2009.
The figures come from a memo obtained by the Associated Press.
Never miss a local story.
ACL problems are the most severe knee injuries, the AP said.
Quintiles teamed up with the NFL in 2011 to update the league’s Injury Surveillance System. Quintiles Outcome also provides the NFL with epidemiological and biostatistical analysis of injury data.
