Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 60 years
  • All sexes
  • No healthy volunteers
  • Adult

Who may be able to join

  • patients aged 18 to 60 years with an acute closed single-legged complete ATR who underwent open surgery with our suture technique.

Who cannot join

  • patients with prior Achilles tendon rupture or other situations that affected their lower limb functions or tendon healing (e.g., autoimmune disease, diabetes mellitus, systemic corticosteroid treatment).
  • an inability to complete our suture technique (e.g., the distance from the rupture site to the Achilles tendon insertion was less than 3.5 cm) .
  • those without rehabilitation or follow-up outcomes.

About this study

This study is a prospective randomized controlled clinical study. After the novel Achilles tendon rupture repaired , patients were randomly divided into 4 groups according to immobilisation duration of 0, 2, 4, and 6 weeks, respectively. All patients underwent the same suture technique with a similar rehabilitation protocol and were examined clinically at 2, 4, 6, 8, 10, 12, 14, 16, 24, and 48 weeks to study the difference in efficacy among the groups.

Read the detailed description

This prospective randomized controlled clinical study is designed to compare the treatment outcomes of different immobilisation duration by dividing the patients into four groups according to immobilisation duration of 0, 2, 4, and 6 weeks after a similar suture technique. The primary outcome was the time of return to light sports activity (LSA). Secondary outcomes included range of motion (ROM) and single-legged heel rise height (SHRH). Data on operation time, complications, visual analogue pain scale (VAS), American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot score, and Achilles tendon Total Rupture score (ATRS) were also collected. Demographic baseline data were analysed using one-way analysis of variance; outcome parameters were analysed using Kruskal-Wallis H test, and complications were analysed using Fisher's exact test. Statistical significance was considered at P ≤ 0.05.

The inclusion criteria were patients aged 18 to 60 years with an acute closed single-legged complete ATR who underwent open surgery with our suture technique.

The excluded criteria were patients with prior ATR and those without rehabilitation or follow-up outcomes. Other situations that affected patients' lower limb functions or tendon healing (e.g. autoimmune disease, diabetes mellitus, systemic corticosteroid treatment) were also excluded.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The time of return to light sports activity

    When the patients are able to do jogging or rapid walk after the surgery, the time will be recorded

    Measured: From operation to 1-year follow-up after the surgery

Secondary outcomes (2)
  1. Range of motion (ROM) recovery time

    The recovery time will be recorded when the ROM is similar to that of the uninjured side.

    Measured: From operation to 1-year follow-up after the surgery

  2. Recovery time of the single-legged heel rise height (SHRH)

    The heel rise height is measured as the distance from the ground to the heel when the patient lift the heel while keeping the knee straight. The recovery time is noted when the SHRH is similar to that of the opposite leg.

    Measured: From operation to 1-year follow-up after the surgery

Questions about this trial

What is this clinical trial studying?

A study testing immobilisation duration in people with Achilles Tendon Rupture, run by Peking University Third Hospital at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 9 Jul 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The time of return to light sports activity (time frame: From operation to 1-year follow-up after the surgery). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Jul 2021.
