What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
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 This study
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 Results may not be published yet.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

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This trial compares three methods of securing a new anterior cruciate ligament (ACL) graft to the shinbone during knee reconstruction surgery. Adults with a complete ACL tear who receive a hamstring tendon graft will be randomly assigned to one of the fixation techniques. The study uses imaging and knee function scores to see which method leads to better bone-to-graft healing, graft maturation, and overall knee stability.

What this could mean

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

Active substance
Three tibial fixation methods for ACL reconstruction: a bioabsorbable interference screw sized to the tunnel, a screw one millimeter larger, and a screw plus a cortical button.
What this could lead to
If one fixation method proves superior, it could refine ACL surgery to improve graft healing and knee stability, potentially reducing re-rupture rates.
What could go wrong
This is a single trial with a modest sample size, and results may not apply to all patients. Differences between methods might be small, and long-term outcomes beyond one year are not assessed.

Study facts

What this study's own registry entry says, in plain language.

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 111 people

The number the study aims to enrol. It can still change while the study runs.

Started

Jan 2023

Expected to finish

Dec 2026

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

18 to 55 years

Sex

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

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 years. Complete ACL rupture treated with arthroscopic ACL reconstruction using autologous hamstring tendons. Exclusion Criteria Age ≥55 years. Patients treated with allografts, bone-patellar tendon-bone grafts, or quadriceps tendon grafts. Malpositioned tunnels (evaluated by MRI at 6 months postop). Previous knee surgery. Femoral or tibial deformities. Multiligament injuries. Note: Soft tissue procedures (e.g., meniscal repair) are not exclusion criteria.
