This study measured knee frontal plane projection angle (FPPA) and sports safety and performance perceptions of female athletes during a single leg triple hop for distance for 3 conditions (standard knee sleeve, no device and distal thigh compression garment (DTCG)). The hypothesis was that the DTCG group would display superior dynamic knee valgus FPPA compared to the standard knee sleeve and no device groups.
Eighteen healthy college athletes participated in this prospective cohort study with a randomized device order. FPPA was measured during single leg triple hop for distance using two-dimensional biomechanical techniques to estimate dynamic knee valgus loading. A 10-cm visual analog scale survey collected data regarding subject perceived knee control, sports movement capability and overall satisfaction for each condition. Pearson correlations delineated knee valgus, safety and performance relationship perceptions (p < 0.05).
