Total Joint

Joint replacement surgery used to mean spending the better part of a week lying in a hospital bed, and going home with an expensive bill. But patients in the Ankeny and surrounding areas have a better choice.

Ankeny Medical Park Surgery Center and DMOS Physicians offer same-day total joint replacement surgery for shoulders, hips and knees. This innovative outpatient procedure represents the greatest advancement in total joint surgeries in over 15 years. DMOS’ expert surgeons and staff and Surgery Center facilities serve as a safe, non-hospital option for patients who are healthy enough for the procedure.

“What is Total Knee Replacement surgery?”

The knee joint is composed of three parts: the end of the femur (thigh bone), the top of the tibia (shin bone), and the patella (knee cap). In a normal knee, these three bones are covered with a smooth cartilage that cushions the bones and enables them to move easily. In the arthritic knee, the cartilage layers are destroyed resulting in bone rubbing against bone which causes pain, muscle weakness and limited motion. Total knee replacement surgery involves the resurfacing of the knee joint. Metal components are cemented to the ends of the bones and a plastic liner is inserted between them. The kneecap is also resurfaced with a plastic liner. When in place, these components move together to allow normal motion of the knee joint. Bow leg or knock knee deformity can usually be corrected by the new alignment.

“What is Total Hip Replacement surgery?”

Your hip joint is composed of two parts:  the round head of the femur (the ball) and the acetabulum (the cup or socket in your pelvis). In a normal hip joint these two bones are coated with smooth articular cartilage that allows them to move against each other without friction or pain. In an arthritic hip, the cartilage layers are destroyed, and bone rubs against bone causing pain and limiting motion.  Hip replacement surgery replaces your arthritic hip joint with an artificial joint composed of a ball component and a socket component.  The metal ball is attached to a stem that fits into your thigh bone. This component can be cemented or non-cemented depending on your age and the condition of your bone. A plastic liner with an outer metal sheet is secured into your pelvis.  A combination of a cemented ball and a non-cemented socket also may be used. Your orthopedic surgeon will choose the type of components that best meets your individual needs.  Once in place, the artificial ball and socket functions in essentially the same manner as your natural hip.
