Objective

Supracondylar femur periprosthetic fractures about a total knee arthroplasty (TKA) are a catastrophic and challenging complication of TKA and unfortunately are increasing in incidence. Fixation of these fractures can be challenging due to altered anatomy for the TKA and the presence of the metallic femoral component and have a relatively high complication rate. As a result, some surgeons elect to treat these fractures with a distal femur replacement total knee arthroplasty (DFR). The purpose of this study is to prospectively evaluate periprosthetic femur fractures treated with ORIF or DFR and compare various outcomes measures (Get up and go times, KOOS Jr score)

Description

Supracondylar femur periprosthetic fractures about a total knee arthroplasty (TKA) are a catastrophic and challenging complication of TKA and unfortunately are increasing in incidence. Fixation of these fractures can be challenging due to altered anatomy for the TKA and the presence of the metallic femoral component and have a relatively high complication rate. As a result, some surgeons elect to treat these fractures with a distal femur replacement total knee arthroplasty (DFR). Several small retrospective studies have compared outcomes with mixed results. To the authors' knowledge there are no prospective studies evaluating the outcomes after treatment of periprosthetic distal femur fractures. The purpose of this study is to prospectively evaluate periprosthetic femur fractures treated with ORIF or DFR and compare various outcomes measures (Get up and go times, KOOS Jr score).

    Get screened to confirm eligibility

    You may be asked to take part in prescreening to make sure you are eligible for a study. The prescreening process ensures it is safe for you to participate. During the prescreening process, you will be asked some questions and you may also be asked to schedule tests or procedures to confirm your eligibility.

  3. Step
    3

    Provide your consent to participate

    If you are eligible and want to join the clinical trial or study, a member of the research team will ask for your consent to participate. To give consent, you will be asked to read and sign a consent form for the study. This consent form explains the study's purpose, procedures, risks, benefits and provides other important information, such as the study team's contact information.
