STAR - Support and Treatment After Replacement

Many people have total knee replacement operations because of the pain caused by osteoarthritis. Unfortunately, around 20% of these people (one in five) will have moderate or severe long-term pain after their operation.

This means that roughly 15,000 people in the UK every year will have long-term pain after knee replacement surgery.

A set of development projects were supported by the National Institute for Health Research through a Programme Development Grant in 2013-14. That work provided the background to a 5-year programme of research into long-term pain after knee replacement.

The STAR Programme

The STAR programme began in September 2015 and has six parts.

  1. Working out what happens after surgery that might indicate whether someone will get long-term pain afterwards, through study of published research (systematic reviews) as well as looking in detail at existing research data 

    Systematic reviews have been completed in the areas of:
    - identifying treatments that work for long-term pain after surgery 
    - risk factors present after knee replacement that might affect long term pain
    - treatments after knee replacement for preventing long-term pain

    A further two systematic reviews on  treatments before and around the time of knee replacement for preventing long-term pain have been registered, completed and await publication.

  2. Finding out what happens to people living with long-term pain, including how much it costs them and the health services to have this type of pain (a cohort study and analysis of data from the National Joint Registry (NJR) with linkage of other healthcare information) 

    Large datasets from the NJR alongside data from NHS Digital are being used during this study. The personal identifiers of patients who had knee replacement surgery and consented for their details to be stored in the NJR have been securely transferred to NHS Digital.  NHS Digital links the data to information it collects and extract details of all hospital admissions (HES) for the study cohort and Patient Recorded Outcome Measures (PROMS).  NHS Digital securely transfers the linked data to the University of Oxford as pseudonymised data (i.e. all identifiers are removed and replaced with a unique patient ID).  The NJR securely transfers pseudonymised information from its records to the University of Oxford using the same unique ID so that the data can be linked by the University of Oxford and processed in such a way that researchers cannot identify patients.  
    Access patient information, and the NJR study website, here.

  3. Finalising best ways to care for people with long-term pain, which has now been published here

  4. Testing out best ways to provide care for people with long-term pain, in a large project in eight hospital sites (a randomised controlled trial) (registered in September 2016 with the ISRCTN; protocol published in Trials). As part of trial processes, we  developed a clickable bodymap that can be used by other bona fide researchers working in the field of pain.  We have also published a paper about recruitment into trials (see here).  

  5. Finding out why some people do not use healthcare services for their long-term pain after knee replacement (a qualitative study)

  6. Putting research findings into practice (using implementation science)

The study was developed in collaboration with the University of Bristol’s Musculoskeletal Research Unit’s patient involvement group, PEP-R, and in collaboration with Versus Arthritis. The study has benefited greatly from user involvement.

NIHR New Media competition winners
In March 2016 we made a short film. Later that year, it was announced that this film had won a special prize for demonstrating "the positive impact of embedding patient and public involvement into a research project".

We will provide links to findings from the programme on this website in due course.
