Hip surgery risks
The complication rate following hip replacement surgery is low. Serious complications, such as joint infection, occur in less than 2% of patients. Major medical complications, such as heart attack or stroke, occur even less frequently. However, chronic illnesses may increase the potential for complications. Although uncommon, when these complications occur they can prolong or limit full recovery.
Infection may occur superficially in the wound or deep around the prosthesis. It may happen within days or weeks of surgery. It may even occur years later.
Minor infections of the wound are generally treated with antibiotics. Major or deep infections may require more surgery and removal of the prosthesis. Any infection in your body can spread to your joint replacement.
Blood clots in the leg veins or pelvis are one of the most common complications of hip replacement surgery. These clots can be life-threatening if they break free and travel to your lungs.
We will outline a prevention program which may include blood thinning medications, support stockings, inflatable leg coverings, ankle pump exercises, and early mobilization.
Sometimes after a hip replacement, one leg may feel longer or shorter than the other. Your orthopaedic surgeon will make every effort to make your leg lengths even but may lengthen or shorten your leg slightly in order to maximize the stability and biomechanics of the hip. Some patients may feel more comfortable with a shoe lift after surgery.
Hip implant dislocation occurs when the ball comes out of the socket.
The risk for dislocation is greatest in the first few months after surgery while the tissues are healing. Dislocation is uncommon. If the ball does come out of the socket, a closed reduction usually can put it back into place without the need for more surgery. In situations in which the hip continues to dislocate, further surgery may be necessary.
Loosening and Implant Wear
Over the years, the hip prosthesis may wear out or loosen. This is most often due to everyday activity. It can also result from a biological thinning of the bone called osteolysis. If loosening is painful, a second surgery called a revision may be necessary.
Nerve and blood vessel injury, bleeding, fracture, and stiffness can occur. A small number of patients continue to experience pain after surgery.
Preparing for surgery
If you decide to have hip replacement surgery, we may ask you to have a complete physical examination by your primary care doctor before your surgical procedure. This is needed to make sure you are healthy enough to have the surgery and complete the recovery process. Many patients with chronic medical conditions, like heart disease, may also be evaluated by a specialist, such a cardiologist, before the surgery.
Several tests, such as blood and urine samples, an electrocardiogram (EKG), and chest x-rays, may be needed to help plan your surgery.
Preparing Your Skin
Your skin should not have any infections or irritations before surgery. If either is present, contact your orthopaedic surgeon for treatment to improve your skin before surgery.
Tell your orthopaedic surgeon about the medications you are taking. He or she or your primary care doctor will advise you which medications you should stop taking and which you can continue to take before surgery.
If you are overweight, your doctor may ask you to lose some weight before surgery to minimize the stress on your new hip and possibly decrease the risks of surgery.
Although infections after hip replacement are not common, an infection can occur if bacteria enter your bloodstream. Because bacteria can enter the bloodstream during dental procedures, major dental procedures (such as tooth extractions and periodontal work) should be completed before your hip replacement surgery. Routine cleaning of your teeth should be delayed for several weeks after surgery.
Individuals with a history of recent or frequent urinary infections should have a urological evaluation before surgery. Older men with prostate disease should consider completing required treatment before having surgery.
Although you will be able to walk with a cane, crutches, or a walker soon after surgery, you may need some help for several weeks with such tasks as cooking, shopping, bathing, and laundry.
If you live alone, a social worker or a discharge planner at the hospital can help you make advance arrangements to have someone assist you at your home.
Several modifications can make your home easier to navigate during your recovery. The following items may help with daily activities:
- Securely fastened safety bars or handrails in your shower or bath
- Secure handrails along all stairways
- A stable chair for your early recovery with a firm seat cushion (that allows your knees to remain lower than your hips), a firm back, and two arms
- A raised toilet seat
- A stable shower bench or chair for bathing
- A long-handled sponge and shower hose
- A dressing stick, a sock aid, and a long-handled shoehorn for putting on and taking off shoes and socks without excessively bending your new hip
- A reacher that will allow you to grab objects without excessive bending of your hips
- Firm pillows for your chairs, sofas, and car that enable you to sit with your knees lower than your hips
- Removal of all loose carpets and electrical cords from the areas where you walk in your home
Avoiding problems after surgery
Recognizing the signs of a blood clot
Follow instructions carefully to reduce the risk of blood clots developing during the first several weeks of your recovery. We may recommend that you continue taking the blood thinning medication you started in the hospital. Notify your doctor immediately if you develop any of the following warning signs.
Warning signs of blood clots. The warning signs of possible blood clot in your leg include:
- Pain in your calf and leg that is unrelated to your incision
- Tenderness or redness of your calf
- New or increasing swelling of your thigh, calf, ankle, or foot
Warning signs of pulmonary embolism. The warning signs that a blood clot has traveled to your lung include:
- Sudden shortness of breath
- Sudden onset of chest pain
- Localized chest pain with coughing
