Community based Rehabilitation after Knee Arthroplasty(CORKA). A prospective individually randomised two arm randomised controlled trial

Start Date: 1 Aug 2014 End Date: 31 Oct 2016

Project summary

The existing literature demonstrates that predicting who will do well after knee replacement is a complex construct and not a simplistic linear relationship between factors such as age or pre-surgical function. A number of studies have investigated the influence of preoperative predictors on postoperative outcome of knee replacement. However, no screening algorithm that can accurately identify and predict who is at a risk of poor postoperative outcome associated with rehabilitation is currently in existence. The CORKA study will investigate the effect of a multicomponent community based rehabilitation programme on patients that are at risk of a poor outcome after knee replacement surgery identified by a screening algorithm. 
Once the patient has had knee surgery they will be re-checked for eligibility and re-confirm consent. They will then be randomised to one of two groups, either Usual care or a Community Rehabilitation programme led by rehabilitation assistants.
The study design is a prospective individually randomised controlled trial with blinded outcome assessment at baseline, 6 and 12 months. It will also include a qualitative study to ask participants and staff their views and experiences of the study and a health economic analysis that will be collected from Participant diaries and questionnaires at the 3 time points.
