Acute Achilles Tendon Rupture - Choice of Treatment Based on Ultrasound Findings (DUSTAR)

May 28, 2024 updated by: Katarina Nilsson Helander, Sahlgrenska University Hospital, Sweden

Diagnostic UltraSonography for the Choice of Treatment of Acute Achilles Tendon Rupture

Patients with acute achilles tendon rupture will go through an acute ultrasound. Based on the distance between the ends of the tendon the investigators will decide if the patient is going to be treated with or without surgery.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

16 years to 65 years (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Difference in functional outcome between patients treated surgically and non-surgically
Time Frame: 3 months
The primary outcome will be a comparison of function by the heel-rise work test developed by Silbernagel et al. This is a validated test which combines both the height of each heel-rise and the number of repetitions.
3 months
Difference in functional outcome between patients treated surgically and non-surgically
Time Frame: 6 months
The primary outcome will be a comparison of function by the heel-rise work test developed by Silbernagel et al. This is a validated set of tests measuring vertical jump, strength and endurance
6 months
Difference in functional outcome between patients treated surgically and non-surgically
Time Frame: 12 months
The primary outcome will be a comparison of function by the heel-rise work test developed by Silbernagel et al. This is a validated set of tests measuring vertical jump, strength and endurance
12 months
Difference in functional outcome between patients treated surgically and non-surgically
Time Frame: 24 months
The primary outcome will be a comparison of function by the heel-rise work test developed by Silbernagel et al. This is a validated set of tests measuring vertical jump, strength and endurance
24 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Ultrasonography (US)
Time Frame: 6 months
Achilles tendon length - measured using US extended field of view
6 months
Ultrasonography (US)
Time Frame: 12 months

3 months
Achilles Tendon Rupture Score (ATRS)
Time Frame: 6 months
Patient reported outcome measure (PROM) specific for achilles tendon rupture. Minimum value 0. Maximum value 100. Higher scores mean better outcome.
6 months
Achilles Tendon Rupture Score (ATRS)
Time Frame: 12 months
Patient reported outcome measure (PROM) specific for achilles tendon rupture. Minimum value 0. Maximum value 100. Higher scores mean better outcome.
12 months
Achilles Tendon Rupture Score (ATRS)
Time Frame: 24 months
Patient reported outcome measure (PROM) specific for achilles tendon rupture. Minimum value 0. Maximum value 100. Higher scores mean better outcome.

Physical Activity Scale (PAS)
Time Frame: 3 months
PROM to measure overall physical activity. Minimum value 1. Maximum value 6. Higher scores mean a better outcome.
