BACKGROUND: Little is known about the evolution of anterior cruciate ligament injury rates among elite alpine skiers.
PURPOSE: To evaluate epidemiologic aspects of anterior cruciate ligament injuries among competitive alpine skiers during the last 25 years.
STUDY DESIGN: Descriptive epidemiology study.
METHODS: Data were collected from elite French national teams (379 athletes: 188 women and 191 men) from 1980 to 2005.
RESULTS: Fifty-three of the female skiers (28.2%) and 52 of the male skiers (27.2%) sustained at least 1 anterior cruciate ligament injury. The overall anterior cruciate ligament injury incidence was 8.5 per 100 skier-seasons. The primary anterior cruciate ligament injury rate was 5.7 per 100 skier-seasons. The prevalence of reinjury (same knee) was 19%. The prevalence of a bilateral injury (injury of the other knee) was 30.5%. At least 1 additionalanterior cruciate ligament surgery (mean, 2.4 procedures) was required for 39% of the injured athletes. Men and women were similar with regard to primary anterior cruciate ligament injury rate (P = .21), career remaining after the injury (P = .44), and skiing specialty (P = .5). There were more anterior cruciate ligament injuries (primary, bilateral, re-injuries) among athletes ranking in the world Top 30 (P<.001). Anterior cruciate ligament-injured athletes had a career length of 7.5 years, whereas athletes with no anterior cruciate ligament injury had a career of 4.5 years (P<.001). Finally, injury rates remained constant over time.
CONCLUSION: Anterior cruciate ligament injury rates (primary injury, bilateral injury, reinjury) among national competitive alpine skiers are high and have not declined in the last 25 years. Finding a way to prevent anterior cruciate ligament injury in this population is a very important goal.
