To examine how proximal and distal patellar tendon micromorphology relates to body anthropometrics and lower-limb range of motion in elite volleyball athletes.
Assessed 132 elite volleyball athletes for proximal and distal patellar tendon thickness and collagen organization (peak spatial frequency radius, PSFR) via ultrasound.
Measured body mass, height, waist-to-hip ratio, ankle dorsiflexion, hip rotation, hip extension, and single-leg squat performance.
Athletes with patellar tendinopathy (51.5%) had significantly lower proximal tendon PSFR compared to asymptomatic athletes (1.59 ± 0.32 vs. 1.73 ± 0.31, p = 0.025), with proximal PSFR decreasing with years of play (p = 0.002).
Distal tendon PSFR correlated positively with ankle dorsiflexion (p = 0.039) and hip internal rotation (p = 0.031), but correlated negatively with body weight (p = 0.008), height (p = 0.030), and waist-to-hip ratio (p = 0.022).
