What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Summary

This study compares two surgical approaches for chronic lateral ankle instability: the standard Brostrom repair and a version augmented with a bioinductive implant called BioBrace. The goal is to see if adding the implant improves pain, function, and return to activity. The trial enrolls adults aged 18–65 with chronic ankle instability who have not had prior ankle surgery.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Brostrom repair with BioBrace bioinductive implant
What this could lead to
If successful, this could show that adding a bioinductive implant to standard ankle ligament repair leads to better pain relief and faster return to activity.
What could go wrong
This is a relatively small, early-stage study, and the implant may not provide meaningful benefit over standard surgery. There is also a risk of complications such as infection or implant failure.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 75 people

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Age 18-65 years * Chronic lateral ankle instability (\>3 months) confirmed by clinical examination (positive anterior drawer test or talar tilt \>10°) and imaging (stress X-ray or MRI). * No prior ankle surgery on the affected limb. * Willingness to follow postoperative visits and rehabilitation protocols and filling out the patient reported outcome measures (PROMs) forms. Exclusion Criteria: * BMI\>40 * Significant secondary procedures done at the time of repair, including micro-fracture, or any other treatment of osteochondral lesions of the talus or tibia. * Concomitant deltoid ligament insufficiency. * Any worker's compensation case or any subject with a history of infection of the ankle predating the ankle repair. Current orthopedic issues, not related to the ankle, that prevented the patient from performing the functional tests. * Concomitant osteochondral lesions, significant degenerative changes, or severe varus/valgus deformity, neuromuscular disorders or non-adherence concerns. * Pregnant * Diagnosis of Ehlers-Danlos Syndrome or other connective tissue / hyperlaxity disorder. * Prior revision ankle ligament surgery on the affected limb (any revision Broström or lateral ligament reconstruction).
