Passive stiffness of the ankle and plantar flexor muscle performance after Achilles tendon repair: a cross-sectional study

Highlights • The surgical ankle presented lower stiffness values than the non-surgical ankle in the same subject.• The surgical ankle presented lower stiffness than the non-surgical group.• The SU group had greater absolute asymmetry of ankle stiffness.• The SU group had greater absolute asymmetry of plantar flexor muscle work.
