Lower Extremity Injuries in Elite Snowsport Athletes: A Retrospective Survey

<b>Background/Objectives</b>: Lower extremity injuries represent a major health concern in elite snowsport disciplines, where high mechanical loads, complex movement patterns, and demanding environmental conditions substantially increase injury risk. Understanding injury incidence and burden in this population is essential for developing sport- and sex-specific prevention strategies. This retrospective study determined lower extremity injury incidence and burden among elite snowsport athletes. <b>Methods</b>: Ninety-nine Turkish National Snowsport Teams Training Camp athletes (34 females; 65 males) consented to a review of their medical records for injury incidence. Overall, sex- and sport-specific injury incidence (number/10,000 h) and burden (weeks missing/10,000 h) were calculated. <b>Results</b>: Overall, medial tibial stress syndrome (MTSS) was the highest burden (9.5 ± 38.7), and ankle sprain (1.7 ± 0.4) was the highest-incident injury. However, injury incidence and burden patterns differed by sex and sport. Notably, medial tibial stress syndrome (MTSS) showed comparable incidence in female and male athletes but resulted in a substantial injury burden in both sexes, reflecting prolonged time-loss from training and competition and indicating a meaningful negative impact on athletic performance. Specifically, the highest-burden injury for women was anterior cruciate ligament (ACL) rupture (16.2 ± 64.5), and for men the most common injury was MTSS (9.7 ± 40.7). For cross-country skiers, MTSS had the highest burden and incidence. For all other sports, and across sexes, ankle sprain was the highest incidence injury-women (1.3 ± 3.0), men (2.0 ± 4.5), biathletes (2.3 ± 5.7), Alpine skiers (2.8 ± 4.5), ski jumpers (1.6 ± 3.1), and snowboarders (3.2 ± 4.7)-plus the highest-burden injury for biathletes (6.9 ± 14.3) and ski jumpers (6.0 ± 14.0). The highest burden injury for Alpine skiers was ACL damage (34.3 ± 87.2), and for snowboarders it was knee collateral ligament injury (27.8 ± 78.6). Moreover, patellar tendinitis, hamstring strains, calf strains, Achilles ruptures, anterior tibial pain, meniscus tears, and hip injuries were frequently observed in injury patterns. <b>Conclusions</b>: Ankle sprains were the most frequent lower extremity injury in elite snowsport athletes, whereas medial tibial stress syndrome (MTSS) and anterior cruciate ligament (ACL) injuries accounted for the greatest injury burden. Injury incidence and burden differed by sex and snowsport discipline.
