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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tests whether a wearable sensor that monitors home exercises helps people recover after total knee replacement. Researchers randomly assign 250 adults to either use the sensor or receive standard unsupervised home exercises. The study compares knee function, pain, and quality of life at six months and checks whether the sensor approach is cost-effective.

What this could mean

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

Active substance
a wearable sensor that tracks home-based rehabilitation exercises after knee replacement
What this could lead to
If the sensor helps, it could give patients a way to do guided rehabilitation at home and reduce the need for frequent physiotherapy visits.
What could go wrong
The sensor may not improve recovery more than standard care, and some patients may find the technology hard to use or unreliable. The trial measures outcomes at six months, so longer-term benefits remain uncertain.

Started

May 2022

Expected to finish

Sep 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.

Inclusion Criteria: * • Primary total knee replacement patients * Participant is aged 18 years of age or over * Participant is able and willing to provide written informed consent * Participant with ability to work with smart devices * Participant having own device (Apple iPhone or iPad or Android tablet or smartphone - minimum requirement: IOS - 12.4 or later/Android - 6.5 or later) * Internet connection at patient's home - either Wifi or mobile internet (min. 3G) Exclusion Criteria: * • Participants who are unwilling or mentally and/or physically unable to adhere to study procedures * Participants with dementia or other cognitive impairment which would prevent them from using the sensor/app * Presence of a previous joint replacement in the same knee * Surgical treatment of involved knee within the past 6 months (excluding arthroscopy) * Previous orthopaedic surgery for trauma or arthritis of the knee joint (such as a previous fracture fixation or osteotomy) * Active cancer (currently diagnosed and under treatment) * Unable to complete all trial procedures (e.g. attend follow up visits, complete questionnaires) * Unable to provide informed consent (cognitive disorder such as dementia, psychiatric illness)
