Joint diseases

Introduction

A joint is where two bones meet, like at the knee or shoulder. Joint injuries can be caused by dislocations or strains that force them out of position. Inflammation (arthritis) and swelling (bursitis, fluid on a joint) are signs of damage. They can be painful, reducing movement and may require drug treatment or surgery.
