Rationale for Hip
replacement & resurfacing
 Goal of any joint replacement is to
prevent bones without cartilage
from grinding against each other.
 Rubbing of raw bony surfaces
causes pain.
 Replacing the joint with a
prosthesis abolishes friction and
allows smooth & easy movement,
removing pain.

resurfacing
 To allow the patient to return to
many of their normal activities
without pain and greater freedom
of movement
 To prevent further morbidity

primary THA.
 Hip resurfacing extends continuum
of care in young patients with hip
disease
