ATRBFH: Two-layer Suturing of Achilles Tendon Ruptures
Study Details
Study Description
Brief Summary
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

Outcome Measures
Primary Outcome Measures
- Tendon length [One week after surgery.]
The distance between the distal muscle fibers of the Soleus muscle and the posterior most superior part of the calcaneus.
Secondary Outcome Measures
- Tendon length Soleus [One week after surgery.]
The distance (mm) between the distal muscle fibers of the gastrocnemius muscle and the posterior most superior part of the calcaneus.
- Tendon length Triceps Surae [6 months.]
The soleus and gastrocnemius tendon length (mm).
- Plantar flexion function [6 and 12 months.]
Heel-rise test
- Patient perception [12 months]
Achilles Tendon Total Rupture Score (ATRS). The ATRS consist of 10 items, with a total score range from 0 to 100, and a low score indicate more limitations in physical activity and worse symptoms.
- Vascularisation [6 months.]
Doppler flow (area in mm2)
- Muscle architecture fascicle length [6 months.]
Gastrocnemius and soleus muscle fascicle length (mm).
- Muscle architecture pennation angle [6 months.]
Gastrocnemius and soleus muscle pennation angle (°).
- Muscle cross sectional area [6 months.]
Gastrocnemius and soleus tendon and lower limb muscle cross-sectional area (mm2).
