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 This study
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 Results may not be published yet.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

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

Summary

This trial compares two types of platelet-rich plasma (PRP) injections for people with tennis elbow that hasn't improved with standard treatments. One injection uses PRP made from the patient's own bone marrow, while the other uses PRP from their blood. The study aims to see if the bone marrow version is feasible and may lead to better healing of tendon tears.

What this could mean

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

Active substance
a platelet-rich plasma (PRP) injection made from bone marrow or from blood
What this could lead to
If it works, this could offer a better treatment option for tennis elbow that hasn't healed with standard care, potentially avoiding surgery.
What could go wrong
This is a small pilot study, not designed to prove which treatment is better. The bone marrow PRP may not provide additional benefit and involves a more complex procedure.

Show the full entry requirements

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

Inclusion Criteria: * Diagnosis of chronic lateral epicondylitis with partial-thickness tendon tear of the common extensor tendon confirmed by ultrasound. * Symptoms persisting despite appropriate conservative treatment for at least 3 months. * Indication for platelet-rich plasma (PRP) injection established by the treating physician. * Ability to understand the study procedures and comply with follow-up requirements. * Written informed consent obtained prior to participation. * Affiliation to a health insurance system (as required by French regulations). Exclusion Criteria: * Full-thickness tear of the common extensor tendon. * Previous surgery of the affected elbow. * PRP injection in the affected elbow within the previous 6 months. * Corticosteroid injection in the affected elbow within the previous 3 months. * Current treatment with medications incompatible with PRP preparation according to study procedures. * Active infection at the injection site or systemic infection. * Known hematologic disorder affecting platelet function or coagulation. * Current anticoagulant therapy that cannot be interrupted according to study requirements. * Pregnancy or breastfeeding. * Participation in another interventional clinical trial that could interfere with study outcomes. * Any medical, psychiatric, or social condition that, in the investigator's opinion, could compromise participant safety or compliance with study procedures.
