CHRONIC PAIN
In conclusion, the STAR care pathway, a clinically important and cost-effective intervention over one year for people with ongoing pain at three months after TKR, remains cost-effective at the longer-term follow-up of around four years. The magnitude of the longer-term benefits of the care pathway are less certain due to attrition of trial participants; however, there is a suggestion of some degree of sustained effects at four years in terms of clinical effectiveness, and clear evidence of sustained cost-effectiveness.The STAR care pathway is currently the only evidence-based intervention for people with chronic pain after TKR. Implementation in usual care is needed to improve care and optimise outcomes.
