Achilles tendon cross-sectional area at 12 weeks post-rupture relates to 1-year heel-rise height

摘要: Achilles tendon rupture leads to long-term plantar flexor deficits, but some patients recover functional performance better than others. Early indicators of healing could be helpful in establishing patient prognosis and making individualized decisions regarding rehabilitation progression. The purpose this study was investigate relationships between early morphology mechanical properties heel-rise jumping function individuals after rupture. Individuals were assessed at 4, 8, 12, 24, 52 weeks post-injury. Tendon cross-sectional area, length, measured using ultrasound. Heel-rise jump tests performed 24 52 weeks. Correlation regression analysis used identify structural variables the first 12 weeks outcomes 52 weeks, determine whether addition characteristics 24 weeks strengthened Functional with  3 cm elongation a Mann–Whitney U test. Twenty-two participants [mean (SD) age = 40 (11) years, 17 male] included. area strongest predictor height (R2 = 0.280, p = 0.014) work symmetry (R2 = 0.316, p = 0.008) Jumping not significantly related any measures 12 weeks.

Ultrasound-based structure recovery seem relate later testing. Clinically, assessing has potential as biomarker predict risk negative outcome. II.
