Hip Replacement FAQ
Patients have asked many questions about hip replacements. Below is a list of the most frequently asked questions along with their answers. This should help provide you with additional information. If there are any other questions that you need answered, please ask. We want you to be completely informed about this procedure.
What is arthritis and why does my hip hurt?
In the hip joint there is a layer of smooth cartilage on the upper end of the femur (thighbone) called the femoral head. The femoral head fits within a cup portion of the pelvis bone called the acetabulum. This cartilage serves as a cushion and allows for smooth motion of the hip. Arthritis is a wearing away of this smooth cartilage. Eventually it wears down to bone. Rubbing of bone against bone causes discomfort, swelling and stiffness.
What is a hip replacement?
A hip replacement is really a cartilage replacement with an artificial surface. The hip itself is not replaced, as commonly thought, but rather an artificial substitute for the cartilage that is inserted on the end of the bones. This is done with ball and stem on the femur and plastic cup fit into a metal shell in the acetabulum. This creates a new smooth cushion and a functioning joint that does not hurt.
What are the results of total hip replacement?
Ninety to ninety-five (90-95%) percent of patients achieve good to excellent results with relief of discomfort and significantly increased activity and mobility.
When should I have this type of surgery?
Your orthopedic surgeon will decide if you are a candidate for the surgery. This will be based on your history, exam, x-rays and response to conservative treatment. The decision will then be yours.
Am I too old for this surgery?
Age is not a problem, if you are in reasonable health and have the desire to continue living a productive, active life. You may be asked to see your personal physician for his/her opinion about your general health and readiness for surgery.
How long will my new hip last and can a second replacement be done?
We expect 80-95% of hip replacements to last more than 20-30 years. However, there is no guarantee and the age and activity level can be a factor. A second replacement may be performed if necessary.
Why do they fail?
The most common reason for failure is loosening of the artificial surface from the bone. Wearing of the plastic spacer may also result in the need for a new spacer.
What are the major risks?
Should I exercise before the surgery?
Yes. You should either consult an outpatient physical therapist or follow the exercises provided by the office. Exercises should begin as soon as possible.
Will I need blood?
Most patients do not require blood transfusions after hip replacement surgery. However, we use many pre-operative, intra-operative and post-operative techniques to reduce blood loss and the need for a transfusion. You will have several tests including blood work performed prior to the surgery. Your doctor will use these tests anticipate your potential need for blood products. If you do need blood following surgery, we recommend the blood from the blood bank. This blood is screened thoroughly for infectious disease and recommended by the American Red Cross as safer and more effective when compared to self donation.
How long am I incapacitated?
How long will I be in the hospital?
What if I live alone?
Many of our patients who live alone have arranged for continual home care through their family, local church, or social group, during the first three weeks after surgery. If you decide on private nursing services, we can provide a list of unendorsed service centers for you to review.
Will I need a second opinion prior to the surgery?
How do I make arrangements for surgery?
How long will the surgery take?
We reserve approximately two hours for surgery. Some of this time is taken by the operating room staff to prepare for the surgery.
