Popis: Purpose To determine the relationships among calf muscle function, tendon length and gait biomechanics in patients surgically treated for chronic Achilles tendon rupture. Methods Twenty-one patients with chronic Achilles tendon rupture (mean age 62 ± 13 years) were evaluated by heel-rise endurance test, Achilles Tendon Resting Angle (ATRA), ultrasound measurement of tendon length and three-dimensional gait analysis. A bivariate two-sided correlation test was performed on all variables in all patients. Results Better performance across all parameters of the heel-rise endurance test correlated with faster walking speed (r = 0.52–0.55), greater peak ankle power (r = 0.56–0.64), shorter stance phase (r = −0.52 to −0.76) and less peak ankle dorsiflexion angle (r = −0.49 to −0.64) during gait. Greater ATRA correlated with longer stance time (r = 0.47), greater peak ankle dorsiflexion angle (r = 0.48), less heel-rise repetitions (r = −0.52) and less heel-rise total work LSI (r = −0.44 to −0.59). Conclusion Greater calf muscle endurance, especially heel-rise total work, is moderately correlated (r = 0.49–0.76) to better ankle biomechanics during gait in patients surgically treated for CATR. The heel-rise endurance test may be a clinical proxy for power development in the ankle joint during gait. Level of evidence IV.
