About this study
Official title: Inpatient Versus Outpatient Rehabilitation Following Total Knee Arthroplasty
The purpose of this study is to compare the effectiveness of inpatient and outpatient rehabilitation following total knee arthroplasty. No studies exist that have evaluated these two rehabilitation programmes in a specific orthopaedic patient population with a focus on motor performance. We hypothesized that patients participating in outpatient care tend to be physically more active than patients in the rehabilitation clinic, leading to the assumption that outpatient rehabilitation has superior functional outcomes compared to the inpatient standard-of-care therapy.

We hypothesized that patients participating in outpatient care tend to be physically more active than patients in the rehabilitation clinic, leading to the assumption that outpatient rehabilitation has superior functional outcomes compared to the inpatient standard-of-care therapy.

The record says: finished, as of the sponsor's last update on 23 May 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
physical activity (number of steps) (time frame: during the first seven days of rehabilitation and 3 months post surgery (posttest)). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02120313, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 May 2017; AzTrials last refreshed its copy on 7 Nov 2026.
