No Association Between Anatomic Factors and Non-Contact ACL Injury Risk in 217 Female Team Sport Players: A...

Area of Science:

• Sports Medicine
• Orthopedics
• Biomechanics

Background:

• Non-contact anterior cruciate ligament (ACL) injuries are a significant concern in female athletes.
• Understanding injury risk factors is crucial for developing effective prevention strategies.

Purpose of the Study:

• To investigate the association between specific anatomical factors and the risk of non-contact ACL injuries.
• To examine static knee and pelvic alignment, leg length, pelvic width, and femoral and tibial condyle widths in relation to ACL injury risk.

Main Methods:

• Prospective cohort study involving 217 female team sport players (basketball, floorball, volleyball).
• Baseline physical examinations included measurements of anatomical variables.
• Players were followed for 2.5-4.5 years for new non-contact ACL injuries.
• Generalized linear mixed models were used for statistical analysis.

Main Results:

• Twenty new non-contact ACL injuries were recorded during the follow-up period.
• No significant association was found between any of the measured anatomical factors and the risk of ACL injury.
• This suggests that static anatomical measurements may not be predictive of non-contact ACL injuries in this population.

Conclusions:

• Anatomical factors, as measured in this study, do not appear to increase the risk of non-contact ACL injuries in female team sport players.
• The findings indicate a need to explore other potential risk factors beyond static anatomy for ACL injury prevention.
