Clinical Trial Summary

Overall frame: The overall or "parent" DRAW-project is a large-scale project run in Denmark that aims to provide substantial level 1A evidence-data related to the question: Does rehabilitation after total hip and knee replacements work? In the DRAW project, the authors challenge the belief that physical rehabilitation is clinically important - and surely better than "no physical rehabilitation". To challenge this belief thoroughly, the DRAW project holds many individual work packages centered around the same question. These work packages will be conducted in collaboration with municipality rehabilitation centers in Denmark so that specific usual care strategies are reflected in the different trials and local clinical relevance is as well as implementation potential are increased.

Clinical Trial Description

The DRAW2-trial is a pragmatic, randomised controlled trial that aims to replicate the DRAW1-trial findings (clinicaltrials.gov: NCT03750448, trial protocol: https://f1000research.com/articles/10-146). Based on stakeholder input from Municipality Rehabilitation Bornholm, the DRAW1-trial was designed as a superiority trial to test the hypothesis that physical rehabilitation (telerehabilitation and home-based rehabilitation) is superior to no physical rehabilitation in a mixed population of patients after total hip and knee arthroplasty (THA and TKA, respectively). After DRAW1-trial inclusion was completed and the target sample size reached, an opportunity to continue the trial presented because additional funding was obtained. At the same time, Municipality Rehabilitation Bornholm asked for stratified data (THA/TKA) that could help guide their decision concerning a potential purchase of telerehabilitation equipment (more details on stakeholder input can be found in the trial protocol, https://f1000research.com/articles/10-146). To meet this new research objective of stratified analysis for THA and TKA, it was advised from the local ethical committee that a new and almost identical trial was registered, which would allow for a doubling of the sample simple size, so that adequately powered stratified analyses could be made. This new trial is named the DRAW2-trial. The DRAW2-trial will adhere to the published DRAW1-trial protocol (https://f1000research.com/articles/10-146) and only small logistic modifications to trial procedures have been made. Because some of the DRAW1-trial participants felt overwhelmed by the amount of information they received during the first and only study introduction (usually takes place 5-7 days after surgery), the study introduction in the DRAW2-trial can be divided into two separate consultations a few days apart whenever deemed appropriate by the consulting physiotherapist. The DRAW2 trial will be reported and published independently, including the same outcomes and outcome hierarchy as the DRAW1-trial. As such, it will be an independent replication trial. Research plan While the DRAW2-trial will focus on replication of the DRAW-1 trial findings, the opportunity to run a replication trial at the same trial site with little delay between the two trials will also enable us to address the questions outlined below, by subsequent pooling of data from the two trials. Question 1: Is physical rehabilitation superior to no physical rehabilitation after THA and TKA using two usual care strategies in Denmark (stratified analyses THA vs. TKA by pooling DRAW1 and 2 trial data)? Question 2: Is home-based rehabilitation as good as home-based telerehabilitation in a mixed population of THA and TKA using two usual care strategies in Denmark (equivalence analysis by pooling DRAW1 and 2 trial data)? Question 3: Is physical rehabilitation superior to no physical rehabilitation after THA in general (using DRAW1 and 2 THA trial data in an ongoing living systematic review? (https://www.crd.york.ac.uk/prospero/display_record.php?RecordID=203574). Question 3: Is physical rehabilitation superior to no physical rehabilitation after TKA in general (using DRAW1 and 2 TKA trial data in an ongoing living systematic review? (https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42018094785). ;
