A recent study has found that knee ligament injuries are more common in men than women, despite indications that women’s knees are more prone to anterior cruciate ligament (ACL) tears and surgical repairs.
The study, issued in the American Journal of Sports medicine, used a countrywide database of patients across Sweden to find out how many people had knee ligament injuries and how many had surgical repairs in a period of seven years from 2002 to 2009.
The researchers studied the entire population of Sweden and not just athletes or people from certain regions.
The anterior cruciate ligament is the main stabilizing ligament in the knee, which often injured during sports, such as football, skiing and basketball, engaging quick turns or pivoting movements.
Some 56,659 Swedish tore a knee ligament during the research period, working out to an average of 78 tears for every 100,000 people.
The study found that men had 60 percent of the tears, and that men also accounted for 59 percent of the surgical repairs.
Women experienced ACL injuries between the ages of 11 and 20, while men had such injuries when they were between 21 and 30, the study also showed.
Richard Nordenvall, a researcher from the Karolinska University Hospital, said that the new study counted the entire population of the country while earlier studies only studied at-risk populations.
"In those studies, women are more prone to get injured. The difference with this study is that we studied the general population," he added.
Considering the age groups and the injury rates, the researchers also found that men still had more knee troubles. The figures were about 144 tears for every 100,000 women aged 11 and 20, versus 225 tears for every 100,000 men between 21 to 30 years old.
