The procedure involves replacing the socket portion of the hip with an artificial cup and the ball portion with a metal stem (pin). The ball portion of the hip joint is excised in this procedure.
Total hip arthroplasty is recommended for patients with arthritis of the hip joint who have advanced symptoms which are interfering with the activities of daily living.
There are many types of artificial joints available, primarily differentiated by the type of fixation used to secure them in the hip and the type of bearing surface used at the joint. They can be broadly divided in t o cemented and un-cemented, depending on whether bone cement is used to secure them. Both cemented and un-cemented joint replacements can have metal-metal, metal-plastic (polyethylene) or ceramic-ceramic bearing surfaces (the two sides of the replacement which move against each other).
The procedure takes about 60 minutes.
You will be in the hospital for about 4-5 days. This can vary depending upon your progress while in the hospital. You will be sent home only when you are deemed fit by the multidisciplinary team looking after you.
The complications include infection (<1%), dislocation (<2%), DVT (blood clot) and pulmonary embolism (blood clot travelling to your lungs). There are many other complications which can occur but incidences are very low. Your physician should be able to discuss these in detail.
You will be given injections to prevent blood clots during your stay in the hospital. You will be encouraged to mobilise early to prevent such clots. What care do you take to prevent infection? You will be given antibiotics prior to surgery. All the routine aseptic precautions will be taken to prevent infection during surgery.
You can go back to non-impact activities such as cy cling, swimming, doubles tennis or golf.
