Total Knee Arthroplasty Using Hinge Joints

This article discusses some of the considerations in planning a revision total knee arthroplasty (RTKA). Total knee arthroplasty (TKA) involves replacing all parts of the knee joint to restore functionality and function. TKA is one of the most common and reliable surgical treatments for knee disorders. However, some patients require revision total knee arthroplasty (RTKA) after TKA for a variety of reasons, including mechanical wear, implant loosening, subsidence, infection, instability, periprosthetic fracture, and stiffness. Unfortunately, the overall outcome of RTKA is not as satisfactory as that of primary TKA due to many factors, including success rates and risk factors. Our approach to improving RTKA outcomes includes the use of linked, rotating-hinge revision prostheses, as well as the treatment of patients with metaphyseal bone loss. In preoperative planning of RTKA, we use the classification of bone defects, options for restoring the joint line, which allows for individual selection of the type (kind) and components of a modular revision endoprosthesis. A clinical example also allows for substantiation of the choice of the type (kind) of endoprosthesis, namely a revision endoprosthesis with a rotating hinge.
