52 year old male with aseptic loosening at 3 years

The patient was advised by the surgeon that the implant was rejected.. This is an example of bad cementing or polywear causing loosening.

Removal of debri, washing out the blood, dry field are mandatory before cement application. Pressuring, cement gun introduction and timing of implant introduction depends on the type of cement and room temp.
This was definitely not rejected

  1. I agree completely that the implant was not "rejected". (This diagnosis is specific for a group of Kerala Surgeons who do not want to accept their failures!!)

    It is very unlikely for a Charnley stem to fail this early. Remember that initial cementation techniques were very crude and Sir John had such good results with this stem.
    With a small 22.225 head it is very unlikely that Poly wear is a significant factor in this case. Moreover there is very little evidence of poly wear on x rays.

    The message to all the trainees reading this should be that early(less than 10 years)loosening is infection unless proven otherwise.
    Even with normal CRP/ESR and a negative aspirate I would still treat this as infected
