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 Results may not be published yet.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.

Summary

This trial tests whether shockwave therapy can improve knee function, balance, and fear of movement in adolescents with patellar tendinopathy, a common overuse injury causing knee pain. Fifty teens with pain in one knee will receive low-energy shockwaves to the tendon and thigh muscle. Researchers will measure changes in knee range of motion, balance, and kinesiophobia, which is the fear of moving due to pain.

What this could mean

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

Active substance
Extracorporeal shockwave therapy, a device that delivers low-energy sound waves to the knee and thigh
What this could lead to
If it works, shockwave therapy could offer a non-drug option to reduce knee pain and fear of movement in teens, helping them return to sports and daily activities.
What could go wrong
This is a small, early-stage trial with no comparison group, so results may not apply to everyone. Shockwave can cause temporary pain or bruising, and the benefit may not last.

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

Inclusion Criteria: * Has patellar tendon pain, which limits (at least in part) the quality of normal daily. * Has clinical manifestation of PT (pain and impaired function) confirmed by a clinician. * Has symptoms only in one leg, the other one is asymptomatic. * Normal BMI. Exclusion Criteria: * Any contraindication for ESWT is present (according to the International Society for Medical Shockwave Treatment \[ISMST\] consensus at https://shockwavetherapy.org). * They were aware of any symptomatic mechanical tendon damage in the past (e.g. partial or complete rupture in relation to the injury), neurological, oncological, or systemic disease (e.g. neuropathy, lupus or rheumatic arthritis) coexists * They were already treated for PT elsewhere up to 3 months prior to the study (e.g. platelet- rich plasma therapy, physiotherapy incl. resistance training or ESWT).
