Achilles Tendon Elongation and Gait Pattern After Rupture.

The objective of this study is to determine if Achilles tendon elongation and gait pattern differ between patients treated using an individualized treatment algorithm and patients treated as usual (two control groups; patients treated operatively and non-operatively). The individualized treatment algorithm is based on ultrasonographic status of tendon overlap and Copenhagen Achilles Length Measure (1). Patients are allocated for operative treatment if there the tendon overlap is less than 25 % or the tendon is elongated with 7% or more compared to the healthy, contralateral achilles tendon.
