    Hip Replacement is a surgery commonly performed in Orthopedic practice, wherein the hip joint is changed to a new modular bearing providing painless articulation.

    The common indications of a Hip Replacement surgery are:
    1. Hip Joint Arthritis- either degenerative or inflammatory pathology.
    2. Fracture Neck Femur (upper end of thigh bone)
    3. Malformed hip Joint- a disease of the childhood
    4. Loss of blood supply (Avascular Necrosis)

    The definite indication of Hip Replacement is – Painful hip joint with radiological evidence of   joint space obliteration. Only exclusion is Fracture Neck Femur; wherein a partial change of the bearing component may be performed.



    Will the pain go after surgery  ?

    After a hip replacement, the pain due to arthritis usually subsides in 4-6 weeks. Thereafter, there may be occasional reminders of pain after unaccustomed activity. If however, the pain re-appears after a prolonged pain free period; or the pain tends to worsen progressively, there is a definite cause for concern. This requires an urgent evaluation by the Orthopedic surgeon.

    1. How much time do I need to stay in Hospital; and how much time off work  ?

    As regards hospital stay, the usual duration is 1 week. The timing of going back to previous level of activity depends upon the type of Hip replacement – Cemented/ Un-cemented; and the quality of bone stock. Usually patients may resume office and sedentary work after 4-6 weeks.

    1.  What are the chances that I will need a repeat surgery in future  ?

    The typical longevity of a Hip replacement depends upon- quality of bone/ level of physical activity/ Age/ body weight/ technique of surgery. Most hip replacements survive an average of 15-20 years. However, a large number of variables affecting longevity prevents accurate survival analysis. Individual patient assessment should be done carefully, and the risk- benefit analysis should be explained to the patient before surgery.

    1. What precautions I need to take, and for how long   ?

    The most important of all, are the precautions to be taken by the patient himself. Dislocation of the new joint is a potential risk. extremeof movements should be avoided under all circumstances. The soft tissue healing takes approximately 6 weeks, however, if the hip joint is structurally unstable, or the soft tissue tension is not adequate, precautions need to be taken for a longer time.

    1. What are the different types of Hip Replacement Surgery ?

    Partial hip replacement involves a change of only the femoral head and neck region; acetabular socket is usually preserved. This is preferred in cases of Femoral neck fracture with healthy acetabular cartilage.

    Total Hip Replacement Surgery involves a change of both Femoral head & neck, and Acetabular socket. There are several bearing options which are available depending on the patient requirements.

    Common Bearing Options include, – Metal on Polyethylene/ Ceramic on Polyethylene/ Ceramic on Ceramic.
