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 Results may not be published yet.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
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 study tests whether a short, digitally guided exercise program before total knee replacement is practical and helpful. Sixty adults with knee osteoarthritis will either do the 10-14 day program or receive usual care. The main goal is to see if people stick with it and find it acceptable, with early looks at recovery and function.

What this could mean

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

Active substance
exercise program
What this could lead to
If it works, this could show that a short pre-surgery exercise program helps people recover faster after knee replacement.
What could go wrong
This is a small feasibility study, so it may not prove the program actually improves outcomes. The results might not apply to all patients.

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 60 people

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

Expected to start

Jul 2026

An estimate. Start dates often move.

Expected to finish

May 2027

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.

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

Inclusion Criteria: Eligibility will be determined during the outpatient consultations at the Medical Center in Bad Vigaun. Patients will be screened against the following criteria: * Age ≥18 years at the time of enrolment. * Clinically diagnosed with advanced osteoarthritis and with a medical indication for elective TKR. * Either a scheduled surgery or a documented intention to undergo TKR within the recruitment period. * Elective surgery is scheduled for at least 14 days after enrolment to allow completion of the 10 to 14-day prehabilitation intervention. * Physical ability to safely perform the prescribed exercise program, as confirmed by the treating physician. * Willingness to participate in a digitally supported training intervention at either the center or home-based. * Sufficient digital literacy and access to internet-enabled devices (smartphone, tablet, or computer). * Adequate German language proficiency to follow exercise instructions and study procedures. Exclusion Criteria: Patients will be excluded if any of the following apply: * Pregnancy at the time of enrolment. * Emergency, revisional, or non-elective surgery. * Surgery scheduled less than 14 days after enrolment. * Severe physical impairment or medical contraindication to exercise training (e.g., unstable cardiovascular disease, uncontrolled hypertension, acute musculoskeletal injury). * Patients with contraindications outlined in the Medizinisches Leistungsprofil (MLP) 2.0 that preclude rehabilitation and/or surgery. * Participation in another clinical study that could interfere with the intervention or study outcomes.
