In an article by  By India Sturgis 7:00AM BST 18 Oct 2015 She writes that:

…Bussell has had two operations on her ankle, torn her hamstring and snapped the anterior cruciate ligament in her knee. Last year she had her hip resurfaced…

“I had the resurfacing because I was too young to have a replacement. A lot of retired ballerinas have [hip replacements] but they usually wait until they are in their 60s, not 40s. I just think, look, how lucky are we that we can have titanium put in our bodies and it do wonders,” she says.

Darcey Bussell has much to celebrate this year. She turned 50 a fortnight ago according to The National Lifestyle:

…Four years ago, Bussell had hip resurfacing surgery, a procedure typically carried out on patients in their 60s and above, but not unusual for dancers at a much younger age because of the unnatural stress placed on their bodies during their careers.
