NEW YORK (Reuters Health) - Women skiers are more likely than men to injure a knee while skiing, and a new study shows they are about twice as likely to have that injury occur to their non-dominant leg, often the left one.

.

The study did not go so far as to explain these inequalities, but Dr. Robert Johnson, a sports medicine physician at the University of Vermont College of Medicine said it could be caused "by a whole herd of issues."

.

"Anatomy, strength patterns, muscle patterns, wider pelvis...it all adds up. It's not just one factor," said Johnson, who was not involved in the research.

.

Earlier studies have shown that women are twice as likely as men to hurt a knee during downhill ski crashes, and three times as likely to tear the knee's anterior cruciate ligament, or ACL.

.

Gerhard Ruedl, lead author of the new study and a researcher at the University of Innsbruck in Austria, said he was interested in looking at whether women's knee troubles had to do with leg dominance.

.

The dominant leg is the one that a person prefers to kick with.

Men were just about equally likely to have injured their left knee as their right, although 87 percent of them were right-leg dominant.

.

Most women, 91 percent, were also right-leg dominant, but twice as many injured their left ACL as their right.

.

Ruedl said women have greater body asymmetry than men with regard to strength and proprioception, the sense of how the body -- in this case, the knee -- is positioned.

.

"Studies show that strength and proprioception is greater in the dominant compared to the non-dominant leg," Ruedl told Reuters Health by email.

.

This could perhaps make women more vulnerable to the strain that is put on the non-dominant knee as a skier turns.

.

"During a carving turn the greatest pressure is on the inside edge of the downhill (outside) ski," he said. "Our results showed that most skiers injured their ACL during a right turn where the left leg (= mostly the non-dominant leg) is the outside leg."
