What Are the Indications for Hinged Implants in Revision Total Knee Arthroplasty?

<p dir="ltr">What are the indications for a hinged implants in revision total knee arthroplasty?</p><p dir="ltr">Response/Recommendation: The three most commonly reported indications for using hinged-design implants in revision total knee arthroplasty (rTKA) are infection, instability, and aseptic loosening. However, these conditions rarely present in isolation and are often accompanied by additional factors such as pain, stiffness/arthrofibrosis, periprosthetic fracture, dislocation/subluxation, malalignment/malposition, mechanical failure, bone loss, patellar complications, and the need for revision of a previously implanted hinged prosthesis. Therefore, hinged implants should be considered in cases where major bone loss or compromised soft tissue and ligamentous integrity renders semiconstrained devices prone to failure.</p><h2>Other Information</h2><p dir="ltr">Published in: The Journal of Arthroplasty<br>License: <a href="http://creativecommons.org/licenses/by/4.0/" target="_blank">http://creativecommons.org/licenses/by/4.0/</a><br>See article on publisher's website: <a href="https://dx.doi.org/10.1016/j.arth.2024.10.126" target="_blank">https://dx.doi.org/10.1016/j.arth.2024.10.126</a></p>
