Revision Total Hip Arthroplasty Clinical Trial
Official title:
Effect of an Exercise Intervention Targeting Hip Strengthening in Patients Undergoing Revision Total Hip Replacement - a Multicenter, Randomized Controlled Trial (The Strong Hip Trial)
There is sparse evidence on revision total hip replacement (THR), regarding the effectiveness on pain and function, and no consensus exists on optimal rehabilitation after revision THR. Further, patients undergoing revision THR achieve worse clinical outcomes on hip pain and function compared to patients undergoing primary THR. The primary aim of this randomized controlled trial is to compare the clinical effectiveness of a partly tele-delivered exercise intervention targeting hip strengthening with the standard community-based rehabilitation (usual care) in patients undergoing revision THR. The investigators will test the hypothesis that the exercise intervention targeting hip strengthening is superior to standard community-based rehabilitation in improving physical function measured with the 30-second Chair Stand Test at 16-week follow-up.
There is sparse evidence on revision total hip replacement (THR), regarding the effectiveness on pain and function, and no consensus exists on optimal rehabilitation after revision THR. Revision THR is one of the more technically challenging orthopedic surgeries and patients undergoing revision THR report improvements in pain and function. Nevertheless, patients undergoing revision THR achieve worse clinical outcomes on hip pain and function compared to patients undergoing primary THR. This calls for research exploring different rehabilitation approaches, in order to improve clinical outcomes for patients after revision THR. This study aims to compare the clinical effectiveness of a partly tele-delivered exercise intervention targeting hip strengthening with the standard community-based rehabilitation (usual care) in patients undergoing revision THR. This randomized, controlled, assessor-blinded trial is a multicenter trial involving hospitals and municipality rehabilitation centers across Denmark. Eligible patients undergoing revision THR will be randomized into two groups: A partly remotely-delivered hip strengthening rehabilitation intervention (strength group) or usual care (control group). The exercise intervention targeting hip strengthening will partly follow the Neuromuscular Exercise (NEMEX) program as described by Eva Ageberg et al., and the intervention is further modified based on expert opinion from patients' experience with rehabilitation from a prior qualitative study. Usual care consists of rehabilitation in the municipalities, where it is up to the individual physiotherapist and the municipality to organize the rehabilitation, which is why both type, content, and duration may vary. The primary outcome will be change in functional performance measured by the 30-second Chair Stand Test. Outcomes will be measured at baseline, after 16 weeks of intervention, and at 12-month follow-up. The investigators hypothesize that the exercise intervention targeting hip strengthening is superior to usual care in improving physical function measured with the 30-second Chair Stand Test at 16-week follow-up. ;
