THR: Total Hip Replacement Surgery

    About the Treatment

    Total hip replacement can be defined as the process of surgically replacing the damaged or infected cartilage and bone of the hip joint using the artificial material. The hip joint is also termed as the ball and socket joint. The cup-shaped part of the pelvis referred to as the acetabulum is the termed as the 'socket' of the hip joint.

  • Complete physical examination of the affected area and its surroundings.
  • The affected area will be evaluated using X-ray & MRI studies which will help the surgeon to determine the extent of damage and abnormalities.
  • Blood tests will be done to rule out any chances of infection. If any infection is detected, then treatment is given to cure the infection before the surgery is scheduled.
  • Patient's entire medication is reviewed. Blood-thinning medications such as warfarin (Coumadin) and anti-inflammatory medications such as aspirin may have to be adjusted or discontinued prior to surgery.
  • Hyper allergy or uncontrollable blood loss should be informed to the doctor before surgery.
  • Losing the extra weight helps you speed up the recovery after the surgery

  • The surgical procedure takes a few hours.
  • General or spinal anesthesia is administered.
  • Incision is made over the hip, and layers of tissues are moved to gain access to hip joint
  • The damaged part of the hip joint is removed, and replaced with a new artificial implant to bring back the alignment and function of your hip.
  • Incision is sutured
  • Different types of designs and material are used in an artificial hip joint. There are two basic components available in all, the ball component and the socket component.
  • The use of prosthetic components will include the "press fit" process where the components will be pushed into the problem area to allow the bone to grow onto the components or they may be cemented together with the bone. The decision to execute the press fit or the cementing process depends on a number of factors, like the strength and quality of the patient's bone. Also, a combination of a cemented stem and a non-cemented socket might be used.
  • The best type of prosthesis will be suggested by your orthopaedic surgeon.

  • After the surgery, the hospital stay will be 3-4 days.
  • Regular exercises will have to be done & the physiotherapist monitors the improvement in the new joint.
  • The patient may be asked to wear compression stockings to keep the pressure on the hip.
  • The operated area needs to be kept clean & protected from infection
  • Stitches and staples will be removed after two weeks of the surgery.
  • Physiotherapy and medication should be continued as advised by surgeon
  • Any untoward incident like fever, redness, or pain at or near the incision point must be reported to the doctor immediately.
  • Other post-operative care like taking small steps while walking, sitting with your legs open and avoiding crossing them over each other, using raised chairs and toilet seats for easing the pressure on the hips, etc. should be followed.
  • Your may be provided with a simple breathing apparatus termed as a spirometer to encourage deep breaths.
  • Usually, one can resume work after 6 to 12 weeks of the surgery.

  • Excessive internal bleeding or at incision point
  • Infection at the incision
  • Occurrence of blood clots in lungs (pulmonary embolism) or legs
  • Prosthesis loosening or wearing out
  • Fracture at the hip joint because of wrong placement or movement
  • Stiffness and chronic pain at the operated area
  • In cases of faulty placements, the hip joint may fail to function in the way it is expected to and may need to go through another surgery
  • During the operation, nerves and blood vessels around the area might be damaged, and this could lead to numbness and weakness in that area.
  • The risks of anaesthesia include potential heart, lung, kidney, and liver damage
  • Change in the length of leg
