Abstract

Objective:

Examine potentially modifiable risk factors (MRFs) for female/woman/girl athletes’ lower-extremity injuries.

Design:

Systematic review with meta- or semiquantitative analyses and Grading of Recommendations, Assessment, Development and Evaluation.

Data sources:

MEDLINE, CINAHL, APA PsycINFO, Cochrane Systematic Review Database, CENTRAL, SPORTDiscus, EMBASE, ERIC searched 30 October or 23 November 2023.

Eligibility:

Primary data studies with comparison group(s) assessing the association of MRFs for sport-related lower-extremity injury(s) with ≥1 female/woman/girl per study group.

Results:

Across 195 studies (n=115; 58.9% female/woman/girl-specific estimates) including 1525662 participants (2.4%females/women/girls), eight injury outcomes were assessed (n=75 general lower-extremity, n=3 groin, n=6hip, n=17 thigh, n=88knee, n=17 lower-leg, n=27 ankle, n=9foot). Sixty-six MRF categories were identified. Substantial heterogeneity in MRFs and injury outcomes exists, with high risk of bias present in 37.4% of studies. Considering female/woman/girl specific estimates, we performed meta-analyses for 10 MRFs (body mass, x (BMI), weekly training distance, muscle strength, artificial turf, off-season plyometric training, readiness to return-to-sport, single-leg hop asymmetry, vertical drop jump peak knee flexion angle and ground reaction force) and semiquantitative analyses for 26 MRFs for a variety of injuries. Meta-analyses suggest no association between any lower-extremity strength outcome (g=0.01, 95% CI −0.11 to 0.14; I²=37.3%; very low certainty evidence) or artificial turf (Incidence Rate Ratio=0.97, 95% CI 0.88 to 1.07; I²=2.4%; low certainty evidence) and various lower-extremity injuries. Higher body mass (g=0.19, 95% CI 0.00 to 0.38; I²=71.7%) and/or BMI (g=0.22, 95% CI 0.09 to 0.36; I²=37.0%) are associated with several lower-extremity injuries (very low certainty evidence).

Conclusion:

This review synthesises a large body of exploratory research, exposes important knowledge gaps and provides a foundation for understanding MRFs for female/woman/girl athlete lower-extremity injuries. PROSPERO registration number PROSPERO CRD42024486715.
