Abstract
- Existing patellofemoral pain (PFP) literature has primarily been focused on quadriceps muscle volume, with limited attention given to the deep and superficial muscle volume of the lower limbs in individuals with unilateral and bilateral PFP. In this paper, we aim to fill this gap. To explore superficial and deep lower extremity muscle volume in women with unilateral or bilateral PFP compared with a normative database of pain-free women. Cross-sectional study. University imaging research center. Twenty women with PFP (10 unilateral and 10 bilateral) and 8 pain-free women from a normative database. We quantified lower extremity muscle volume via 3.0-T magnetic resonance imaging. Two separate 1-way analyses of variance were performed: (1) unilateral PFP (painful versus nonpainful limb) versus pain-free control groups and (2) bilateral PFP (more painful versus less painful limb) versus pain-free control groups. We observed no differences in age and body mass index across groups (P >.05). Compared with the pain-free group, the unilateral and bilateral PFP groups had bilaterally smaller volumes of the anterior (iliacus: P ≤.0004; d range, 2.12–2.65), medial (adductor brevis, adductor longus, gracilis, and pectineus: P ≤.02; d range, 1.25–2.48), posterior (obturator externus, obturator internus, and quadratus femoris: P <.05; d range, 1.17–4.82), and lateral (gluteus minimus: P ≤.03; d range, 1.16–2.09) hip muscles and knee extensors (rectus femoris: P ≤.003; d range, 1.67–2.16) and flexors (long and short head of the biceps femoris: P ≤.01, d range, 1.56–1.93). Women with unilateral and those with bilateral PFP displayed less volume of multiple superficial and deep muscles of the bilateral hips and knees than pain-free women. Interventions should bilaterally target lower limb muscles when treating PFP, and hypertrophy exercises for specific muscles should be explored to increase choices for intervention.
