The ARC Study is UK-wide study investigating how different lifestyle and health factors may affect the outcomes of hip and knee replacements. Most patients are very satisfied after receiving a hip or knee replacement. However, a small number of patients are not happy with the outcome of their operation or experience complications.

We hope the results of this research will improve our understanding of why the operation is not as effective in some patients, and help to identify those patients who may be more likely to have a worse outcome. This will ensure that in the future we are providing the best treatment we can for patients with joint problems, and direct further research to make these operations even more successful.

The study will also establish a database of patients who may be interested in future trials, where we can test lifestyle changes or treatments to see if they improve outcomes.
