Patients have asked many questions about hip replacements. Below is a list of the most frequently asked questions along with their answers.
This guide provides additional information. If there are any other questions that you need answered, please ask your surgeon or Orthopaedic Nurse Clinician. 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 ball of the upper end of the thigh bone (femur) and another layer within your hip socket. This cartilage serves as a cushion and allows for smooth motion of the hip. Arthritis is a wearing away of this cartilage. Eventually, it wears down to bone. Rubbing of bone against bone causes discomfort, swelling and stiffness.

What is a hip replacement?
A total hip replacement is an operation that removes the arthritic ball of the upper thigh bone (femur), as well as damaged cartilage from the hip socket. The ball is generally replaced with a metal ball attached to a stem that is fixed solidly inside the femur. The stem may be glued to the bone with acrylic cement (methylmethacrylate), or the stem may be fixed to the bone with a rough metal surface that the bone should stick to. The socket is usually replaced with a plastic liner that is fixed inside a metal shell. The metal shell of the socket is usually fixed tightly to the bone without glue. Occasionally, screws may be used to hold the socket shell in place. The artificial ball and socket relieves the bones from rub bing and, therefore, the pain is usually relieved.

What are the results of hip replacement?
Results will vary depending on the quality of the surrounding tissue, the severity of the arthritis at the time of surgery, the patient’s activity level, and the patient’s adherence to the doctor’s orders. Ninety to ninety-five 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 orthopaedic 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?
All implants have a limited life expectancy depending on an individual’s age, weight, activity level, and medical condition(s). A joint implant’s longevity will vary in every patient. It is important to remember that an implant is a mechanical device subject to wear and tear that may lead to mechanical failure. While it is important to follow all of your surgeon’s recommendations after surgery, there is no guarantee that your particular implant will last for any specific length of time.

Why might I require a revision?
Just as your original joint wears out, a replacement joint will wear out over time as well. The most common reasons for revision are loosening of the artificial surface from the bone and infection. Dislocation of the hip after surgery is a risk. Your surgeon will explain the possible complications associated with hip replacement.

What are the possible complications associated with joint replacement?
While uncommon, complications can occur during and after surgery. Some complications include infection, blood clots, implant breakage, dislocation, and premature wear–any of which may necessitate implant removal/replacement surgery. Other complications include unequal leg length, nerve injury, foot drop, adverse reactions to anesthesia, stroke, heart attack and death. While these devices are generally successful in attaining reduced pain and restored function, they cannot be expected to withstand the activity levels and loads of normal, healthy bone and joint tissue. Although implant surgery is extremely successful in most cases, some patients still experience pain and stiffness. No implant will last forever; factors such as a patient’s post-surgical activities and weight can affect longevity. Be sure to discuss these and other risks with your surgeon.

Should I exercise before the surgery?
Yes. You should either consult your physician, an outpatient physical therapist, or follow the exercises listed in The Playbook. Exercises should begin as soon as possible.

When will I be able to walk?
When you get to the floor after surgery, the nursing staff will assist you in walking. Physical therapy will begin working with you the next morning and you will be walking with a walker later that day.

How long will I be in the hospital?
Most hip replacement patients will be hospitalized for one to three days after their surgery. There are several goals that you must achieve before you can be discharged.

What if I live alone?
You may return home and receive help from a relative or a friend. You may also have a home health nurse and physical therapist assist you at home for two or three weeks, if needed. There is a possibility that you will require additional care, such as the services provided at Health South Rehabilitation. This will be discussed during your discharge planning.

How do I make arrangements for surgery?
After your surgeon has scheduled your surgery, the Joint Center Secretary will contact you. The Orthopaedic Nurse Clinician will guide you through the program and make arrangements for both pre-op and post-op care. Both roles are described in The Playbook along with phone numbers for both.

How long does the surgery take?
We reserve approximately two to two-and-a-half hours for surgery. Some of this time is used by the operating room staff to prepare for the surgery. You will be away from your family for approximately four hours.

Do I need to be put to sleep for this surgery?
You will have regional anesthesia. There are different types of regional anesthesia including spinal block, epidural block, and peripheral nerve block. The goal of regional anesthesia is to provide a numb leg during surgery along with IV sedation, as needed; you will breathe on your own. Another option is general anesthesia. General anesthesia is what most consider “being put to sleep.” You will discuss specific options for anesthesia at your pre-op screening visit with a nurse and anesthesiologist.

Will the surgery be painful?
There will be pain or discomfort after surgery, but we will keep you as comfortable as possible. The regional nerve block will make you comfortable the day of surgery. As the nerve block wears off, you will be receiving pain medicine around the clock to prevent pain from becoming severe. The type of medication depends on the type of anesthesia used. Patients who have regional anesthesia, specifically a peripheral nerve block, may have a continuous infusion of numbing medicine given through the catheter to bathe most of the nerves that go to the hip. In addition, you will initially need some IV pain medication and later, oral pain medication to help ease your pain.

Who will be performing the surgery?
Your orthopaedic surgeon will do the surgery. An assistant often helps during the surgery; this may include residents and/or physician’s assistants.

How long and where will my incision be?
Total hip replacement incisions generally start on the outside of the buttock or front of thigh and extend down the thigh. They vary in length depending on the size of the patient, the degree of deformity, and the surgeon’s preference.

Will I need a walker or crutches or cane?
Yes. For about six weeks we do recommend that you use a rolling walker, a cane, or crutches. The Joint Center staff can arrange for them, if necessary.

Will I need any other equipment?
Yes. You will need a raised toilet seat. A three-in-one commode chair can be used at the bedside and over the toilet – it is important not to sit too low. A tub bench and grab bars in the tub or shower may also be necessary. This will be decided prior to discharge.

Where will I go after discharge from the hospital?
Most patients are able to go home after a one or two-day Hospital stay. Some may transfer to a rehab facility where the average stay is seven days. The Joint Center staff will help you with this decision and make the necessary arrangements. Your insurance company will explain your options, coverage, and payment regarding discharge plans. Some of your options will be home health with physical therapy, outpatient physical therapy, and inpatient rehab.

Will I need help at home?
Yes. For the first several days or weeks, depending on your progress, you will need someone to assist you with meal preparation, ambulating, and normal daily activities. If you go directly home from the hospital, the Joint Center staff will arrange for a home health care nurse to come to your house, as needed. Family or friends need to be available to help, if possible.  Preparing ahead of time can minimize the amount of help needed.

Will I need physical therapy when I go home?
You may require physical therapy. If so, you will either have outpatient or in-home physical therapy. Patients are encouraged to utilize outpatient physical therapy. The Orthopaedic Nurse Clinician will help you arrange for an outpatient physical therapy appointment. If you need in-home physical therapy, we will arrange for a physical therapist to provide therapy at your home. Following this, you may go to an outpatient facility three times a week to assist in your rehabilitation.

Occupational therapy may also be needed pending recommendations from your hospital stay. Occupational therapy may also be available for in home services.

How long until I can drive and get back to normal activities?
The ability to drive depends on whether surgery was on your right leg or your left leg and the type of car you have. If the surgery was on your left leg and you have an automatic transmission, you could be driving in two to four weeks, as long as you’re no longer taking narcotic pain medication. If the surgery was on your right leg, your driving could be restricted as long as six weeks. Getting “back to normal” will depend somewhat on your progress and may result in your being able to resume driving when you feel that you can safely control your vehicle. Consult with your surgeon or therapist for advice on your activity.

When will I be able to go back to work?
This is a decision that you will make with your physician. Following are some general guidelines:

  • Sedentary work/working from home – 7 to 10 days
  • Nursing – 6 to 12 weeks
  • Warehouse work – 3 months
  • Heavy labor – 3 to 6 months

How often will I be seen by my doctor following the surgery?
You will be seen daily during your hospital stay either by a resident or your staff physician. After discharge, your first post-operative visit will be in two to four weeks. The frequency of follow-up visits will depend on your progress.

Do you recommend any restrictions following this surgery?
Yes. In order to extend the life of your artificial joint, you should avoid high-impact activities, such as running, singles tennis and basketball. Injury-prone sports, such as downhill skiing are also dangerous for the new joint.

What physical/recreational activities may I participate in?
You are encouraged to participate in low-impact activities, such as walking, dancing, golfing, hiking, swimming, and gardening.

Will I notice anything different about my hip?
In many cases, patients who have had hip replacement think that the new joint feels completely natural. However, we always recommend avoiding extreme positions or high-impact physical activity. The leg with the new hip may be longer than it was before, either because of previous shortening due to the hip disease or because of a need to lengthen the hip to avoid dislocation. Most patients get used to the feeling in time. Some patients have aching in the thigh on weight-bearing for a few months after surgery.
