Anterior cruciate ligament (ACL) injuries are the most frequently occurring knee
injuries in alpine skiing and represent a significant challenge for both
professional athletes and recreational participants. Women with their
combination of biomechanical and hormonal risks, as well as novice skiers with
their skill-related influences, are particularly vulnerable to ACL injury. These
injuries account for 15–21% of all knee traumas in the sport, often stemming from
noncontact mechanisms like twisting falls or improper weight distribution
during dynamic maneuvers. The injury risk can be amplified by the interaction
between intrinsic factors, such as sex, age, anatomical characteristics,
neuromuscular imbalances, and extrinsic elements, including equipment setup
and environmental conditions. Females exhibit a threefold higher risk than
males, influenced by hormonal and biomechanical differences, while side-to-side
knee laxity and neuromuscular asymmetries heighten susceptibility in
competitive athletes. Equipment, mainly worn ski boot soles or misadjusted
bindings, contributes to accidents by compromising ski-boot-binding
functionality. Preventative strategies targeting neuromuscular training, proper
equipment maintenance, and education about environmental adaptations show
promise in mitigating the risk of injury due to environmental factors like icy or
grippy snow and cold temperatures. However, reinjury remains a concern,
especially for adolescents returning to sport within two years post-ACL
reconstruction. Through reviewing 28 studies, this paper creates an overview of
the multifactorial cause of ACL injuries in skiing to indicate the need for
individually tailored prevention strategies and to stimulate further research
regarding risk-reducing interventions in skiing.
