Two large, new studies being presented this week at the annual meeting of the American Academy of Orthopaedic Surgeons (AAOS), in New Orleans, are offering new information on the best hip replacement options for younger patients with worn-out hips.

Total hip replacements have been performed on older patients for long enough now that doctors say the results are usually predictable, but less is known about the best ways to replace hip joints in patients who are younger, a group that is increasingly driving demand for these procedures.

In fact, one 2009 study projected that people younger than age 65 could account for more than half of all hip replacement patients as early as next year.
