| description abstract | Abstract. It is crucial to further analyze the causes of hip and knee replacement failure to better enhance the success and minimize the shortcomings of joint replacement in patient outcomes. The purpose of this study is to collect samples of failed hip and knee orthopedic implants from surgeons and analyze the features of those implants to find possible reasons for implant failure so that these causes can be successfully prevented and/or mitigated. Twelve implants were collected and cleaned according to a standard protocol. The implants were analyzed using visual observation and an optical microscope, and initial reports are presented in this study. The preliminary findings suggest that a combination of factors, including material, design, patient, and surgical factors, may contribute to the failure of total hip and knee arthroplasties. Mechanical trauma to the implants may be a contributing factor to hip and knee implant failure, as scratch marks and abrasions were common in the implants collected. The study has several limitations, which are clearly stated in the article. Further research is needed to investigate these factors in more detail, using a larger number of implants and a wider population of surgeons, and to develop strategies to improve the success of these procedures. | |
