Removing a well-fixed femoral sleeve during revision total knee arthroplasty
نویسندگان
چکیده
The following surgical technique describes a case of a 51-year-old man with severe juvenile rheumatoid arthritis that required a 2-stage revision of an infected revision total knee implant. The patient had previously been implanted with a revision rotating platform, constrained condylar device which gained excellent fixation through the use of diaphyseal-engaging stems, and a well-ingrown, fully porous-coated femoral metaphyseal sleeve. To avoid intraoperative complications while removing the femoral sleeve, a novel technique for femoral sleeve extraction was used. Using this technique, the femoral sleeve was successfully removed without intraoperative fracture or substantial bone loss.

Coupling failure between stem and femoral component in a constrained revision total knee arthroplasty.
Knee revision using constrained implants is associated with greater stresses on the implant and interface surfaces. The present report describes a case of failure of the screw coupling between the stem and the femoral component. The cause of the failure is surmised with outline of the treatment in this case with extensive femoral bone loss. Revision implant stability was augmented with the use ...
متن کاملHybrid total knee arthroplasty: 10- to 16-year follow-up.
A cementless femoral component may allow for a smaller surgical incision when a minimally invasive approach is used during primary total knee arthroplasty. Fixation by cement is the gold standard for total knee arthroplasty. The results of cementless total knee arthroplasty are mixed. Cementless femoral components have done well. Although some tibial components have performed well at long-term ...
متن کاملPartial 2-Stage Revision in Chronic Hip Arthroplasty Infections: A Review
Background: Periprosthetic hip infections (PHIs) are troublesome complications of hip arthroplasties. The gold standard procedure for treating chronic PHI is a 2-stage approach. Recently, however, more conservative approaches have been developed to spare the osseointegrated components and avoid sequestra, bone loss, devascularization, and difficult reconstructions. The partial ...
متن کاملRemoval of solidly fixed implants during revision hip and knee arthroplasty.
The removal of solidly fixed implants during revision hip and knee arthroplasty is a technically challenging procedure with the potential for a large amount of bone loss during component removal. This bone loss may compromise the subsequent reconstruction. Careful preoperative planning is essential before undertaking removal of solidly fixed implants. The surgeon should determine the type and s...

Adverse local tissue reaction associated with total hip replacement may occur when mechanically assisted crevice corrosion occurs at metal-metal modular junctions in which at least one of the components is fabricated from cobalt-chromium alloy. Complete removal of components may be associated with significant morbidity; when components are well fixed and in acceptable position, it may be approp...
