Kneecap dislocation (also known as patellar dislocation) is most common in people who've had previous sporting injuries, but can also affect those with joint issues that lead them to dislocate easily, like EDS, hyper-mobility or other genetic problems. Supporting the joint with a kneecap dislocation brace allows for normal movement of the knee without the constant fear of the often painful and uncomfortable issue of kneecap dislocation.
