Alpine skiing ranks among the most popular winter sports worldwide, with an estimated 400 million skier days in a typical year. Alpine skiing is performed in greater than 2000 downhill ski areas spread across 67 countries1 and is associated with about 800 000 injuries per year (2 injuries per 1000 skier days).2
Anterior cruciate ligament injuries in skiing are common
The knee joint is the most frequently affected anatomical location of all ski injuries (approximately 30%) and almost all skiers suffering from knee injuries that require hospitalisation are diagnosed with a tear of the anterior cruciate ligament (ACL).3 Based on an estimated hospitalisation rate of 50%, about 120 000 recreational alpine skiers worldwide may incur a new ACL injury annually. Measures that prevent only 1% of these injuries could reduce ACL injuries by 1200 per year.
Prevention programmes work!
Meta-analyses have evaluated the benefits of specific ACL injury prevention programmes (including plyometric, strengthening, agility, stretching and balance exercises) applied in various sports including soccer, basketball, handball and volleyball, and suggest an injury reduction potential of between 53% and 65% after successful implementation.4 …
