Abstract Summary
As a part of “Non-operative treatment of Achilles tendon Rupture in Central Finland: a prospective cohort study – NoARC” results from the first 12 patients who completed biomechanical assessments 1 year after active, structured, and functional non-surgical treatment of acute Achilles tendon (AT) rupture are reported. Deficits in plantarflexion strength (30%), MG fascicle length (24%) and MG muscle area (18%) explained 86% of variance in preferred gait speed. Tendon was 110% thicker and individual subtendon lengths (soleus, medial and lateral gastrocnemius) were 11-50% longer in the injured leg. Considerable structural and functional asymmetry is present 1 year after AT rupture and non-surgical treatment.
