A new ce-mentless joint replacement technique, called biologic fixation, is now being used for joint replacement in younger, more active people, says the Arthritis Foundation.

In the past, joint replacement surgery involved the use of a special cement to hold the artificial joint in a person's bone cavity. This procedure was not recommended for younger people with active lifestyles, due to the possibility of the cement loosening and weakening the bond between joint and bone.The new technique allows the bone to grow and interlock with the surface of the artificial joint, for a more secure bond with less chance of loosening.
