Joint Replacement
Hip Replacement Surgery
An arthritic joint is prepared by removing worn and damaged joint surfaces, and replacing or resurfacing the joint surfaces with a metal and plastic artificial joint.
Following your anesthetic, the surgeon will trim the damaged parts of the femur ball and socket. Bone cuts are made with precision so that proper leg alignment and length of the leg is maintained. A shortened leg can also be corrected by the surgery.

The type of hip components chosen by your surgeon are based on your age, activity level, and bone quality. The components may be cemented into position with a polymer plastic bone cement. Alternatively, the components may be press-fit components, in which your bone will gradually attach to the prosthesis over a period of several months.
Periodic media reports and attorney solicitation advertisements raise concerns regarding “recalls” of artificial joint systems. The majority of artificial joint “recalls” in the past ten years have involved newer prosthetic designs. These are systems that have only a short track record of durability or survivorship studies. The Sonora orthopedic surgeons select artificial joint systems that have a long track record of success and durability. Please feel free to discuss this with your surgeon.
