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 Results may not be published yet.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.

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.

Summary

This study follows 20 adults aged 18 to 55 who had ACL reconstruction using a peroneus longus tendon graft from their ankle. Researchers will measure ankle strength, balance, walking patterns, and joint position sense at 6-8 weeks, 3 months, and 6 months after surgery, comparing the donor ankle to the other ankle. The goal is to understand how well and how quickly the ankle recovers, which could inform future surgical and rehabilitation decisions.

What this could mean

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

Active substance
Anterior cruciate ligament reconstruction using a peroneus longus tendon autograft
What this could lead to
If successful, this could help surgeons understand how well the ankle recovers after using this graft, potentially improving surgical choices and rehabilitation protocols.
What could go wrong
This is a small observational study (20 participants) without a control group, so results may not apply broadly. It only measures recovery, not the effectiveness of the surgery itself.
