If you have had a total hip replacement surgery, there are certain precautions you need to take, especially if your surgery was done via a posterior approach. You may benefit from the skilled services of a physical therapist for total hip rehab. Your total hip rehab may take place in the hospital, at home, or in an outpatient clinic.

Why Should You Follow Total Hip Precautions?

After a total hip replacement with a posterior incision, three movements should be avoided to prevent dislocation of the hip prosthesis.

Not all patients need to comply with these restrictions, as they differ with the incision location and type of hip prosthesis. However, after many hip replacement surgeries with a posterior located incision, the "new" hip joint can have the tendency to dislocate. To prevent hip dislocation, the three motions to avoid immediately after total hip replacement include:

  1. Hip flexion past 90 degrees. This means that you should not bend your hip up too far or lift your knee too high. In general, your thigh must remain below the parallel line when compared to the floor. Sitting in a low chair or bending your knee and hip up to put on a sock may break this 90-degree rule and put you at risk for hip dislocation.
  2. Crossing your operated leg over your non-operative leg (adduction). When lying down, you should not cross one leg over the other to maintain this hip precaution. When sleeping, many people are required to use a special wedge called an abduction pillow to help keep their legs separated.
  1. Walking pigeon toed (internal rotation of the hip). After a posterior approach total hip replacement, you should not rotate your hip inwards, or you may risk a dislocation. This means that your toes should be kept straight ahead or slightly rotated outwards when sitting, standing, or lying. When walking, be sure not to rotate your body over your foot on the ground in such a way that causes internal rotation of your hip.

    The best way to maintain your total hip precautions is to work closely with your doctor and physical therapist. Your PT can write your hip precautions down so you have a constant reminder.

    Most patients who break their hip precautions do so while simply moving around. Sitting on a low chair or  relaxing with your legs crossed is breaking your hip precautions. Sometimes, exercises, like vigorous straight leg raises, may place your hip in a position where you will be breaking your precautions. Bottom line/ be careful.

    How Long Should You Follow Total Hip Precautions?

    Your doctor will tell you when you are at minimal risk for dislocation and you no longer need to follow your total hip precautions. Most often, people need to maintain total hip precautions for approximately 90 days after surgery. Some doctors may have you maintain you hip precautions for about 6 months, others may only have you watch your motion for 60 days. If you have any questions about your hip motions after your surgery, make sure you contact your doctor and ask about your total hip precautions.

    Remember that each and every person heals differently after total hip replacement surgery, Working with your physical therapist is the best way to ensure a safe and rapid recovery after your total hip replacement.
