I use implants that have excellent track record. I do not use implants that are in a post marketing phase or in the research phase of the life. Occasionally a patient requests certain company. I caution them that there are many companies pushing to consumer products but I only use implants that have a good record of accomplishment irrespective of direct patient to consumer marketing by joint replacement companies.
Joint replacement surgery is doing the same procedure repeatedly in a consistent manner and I do not change the implant company that I use based on individual patient requests. I use the implant company I know well and that has provided good results in my hands. Implant companies have used celebrities to promote hip replacements. The results of companies pushing their own product as compared to their competitors has not been substantiated on scientific basis for the most part.
Several implant companies have several models and designs that defer from each other. Some designs are better for the unique anatomical fit of the patient. I look carefully at the bony anatomy of the patient and the templating of the hip Xray that is done preoperatively. My implant choices occasionally change depending on the individual bony anatomy of the patient.
For the patients getting robotic hip replacement surgery, the implants used have to be compatible with robotic platform. Some implants that are not compatible with robotic platform cannot be used if the patient is getting a robotic hip replacement. For the most common type of hip replacement surgery there is very little difference in the implants offered by most manufacturers. I personally do not get paid by any company to promote or use any of his products.
