Total Hip Replacement

Total hip replacement removes the worn ball at the top of the thighbone and the socket it turns in, and replaces both with artificial parts. It is done most often for hip arthritis that no longer responds to medication or physical therapy. The hospital stay is short, but rebuilding strength takes weeks to months.

What it is

The hip is a ball-and-socket joint: the rounded top of the thighbone sits in a cup in the pelvis, with a layer of cartilage letting the two glide against each other. When that cartilage wears away, bone grinds on bone. In a total replacement the surgeon removes the damaged ball and reshapes the socket, then fits an artificial cup into the pelvis and a stem down the inside of the thighbone with a new ball on top. The parts are made of metal, ceramic and plastic in various combinations, and are either cemented in place or made with a surface that bone grows into. "Total" is the word that separates this from a partial replacement, where only the ball is replaced and the patient's own socket is left alone.

Why it is done

  • To relieve hip pain from arthritis that keeps someone from walking, climbing stairs, or sleeping, once medication and physical therapy have stopped helping
  • To restore movement to a hip that has become too stiff for ordinary tasks like putting on shoes
  • To treat a hip damaged by a fracture, or by osteonecrosis, where the blood supply to the ball of the joint has failed
  • Less commonly, to deal with a tumor involving the joint

What to expect

The operation takes roughly one to three hours under general or regional anesthesia. Patients are usually up and moving with a walker the same day or the next, and many go home within a day or two — some centers do selected hip replacements as an outpatient procedure. Physical therapy starts early and continues for weeks. Light everyday activity typically returns over the first month or two, with strength and endurance improving for much longer. Artificial hips wear out eventually, and a younger or more active patient is more likely to need a second operation later in life.

Questions worth asking

  • Is this being booked as an inpatient admission or as an outpatient stay? The surgery is the same, but the two are billed very differently and insurers treat them differently.
  • Is the implant itself included in the hospital's charge, or listed as a separate device line?
  • Does the surgeon's fee include the follow-up visits during the recovery period, or are those billed on top?
  • Will physical therapy be at home, at an outpatient clinic, or in a rehabilitation facility — and how many visits does my plan allow?
