Development of Achilles Tendon Elongation and Its Effect on Physical Function the First Year After Rupture

Hvidovre University Hospital

Status: Completed

Conditions: Achilles Tendon Rupture

Study type: Observational

Funder types: Other

Identifiers

NCT03525314

Achilles HVH Cohort

Details and patient eligibility

About

The objective of this study is to examine how elongation of the Achilles tendon develops during the first year after rupture among patients with an Achilles tendon rupture, and how it affects physical function.

The aim is to define a cutoff of acceptable elongation dividing the patients who obtain normal physical function (Limb Symmetry Index > 90%) from those who do not.

Patients treated both operatively and non-operatively will be included.

Enrollment: 67 patients

Sex: All

Ages: 18 to 65 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Appointment in the Outpatients Department within 4 days of injury.
• Total Achilles tendon rupture.
• Initial treatment with split cast with the ankle in maximal plantar flexion must be started within 24 hours of injury.
• The patient must be expected to be able to attend rehabilitation and postexaminations.
• The patient must be able to speak and understand Danish.
• The patient must be able to give informed consent.

Exclusion criteria

• Rupture of the Achilles tendon either at the insertion on the calcaneus or at musculotendinous junction of the triceps surae.
• Previous rupture of the Achilles tendon in any of the two legs.
• Treated with Fluorquinolons or corticosteroids within the last 6 months.
• In medical treatment of diabetes.
• Suffers from rheumatic disease.
• Other conditions prior to the injury resulting in reduced function of any of the two legs.
