Two-layer Suturing of Achilles Tendon Ruptures

The purpose of the present study is to measure whether a new technique of double row suturing of a ruptured Achilles tendon will result in a normalization of the length of the Soleus part (primary outcome) and of the superficial Gastrocnemius part of the tendon (secondary outcome) one-week post-operative. Results will be compared to that of a participants group that underwent the same operation but with a standard operative technique and the same rehabilitation regime recently completed (NCT04263493).The investigators hypothesize that the new suturing technique will result in an elongation of the Soleus part of the Achilles tendon (primary outcome) by 8.9 mm or less relative to the uninjured contralateral side one week (primary endpoint) after surgery compared to retrospective data from a recently completed randomized controlled trial
