Follow-Up of a Modular Rotating Hinge Knee System in Salvage Revision Total Knee Arthroplasty

Abstract We evaluated the clinical and radiographic outcomes of salvage knee revisions using a modern-generation, modular, rotating hinge total knee prosthesis in 24 cases with a minimum follow-up of 36 months (mean, 56 months). Indications for revision included aseptic loosening, combined with bone...

Description
Summary:Abstract We evaluated the clinical and radiographic outcomes of salvage knee revisions using a modern-generation, modular, rotating hinge total knee prosthesis in 24 cases with a minimum follow-up of 36 months (mean, 56 months). Indications for revision included aseptic loosening, combined with bone loss and gross collateral ligament instability in all cases. Patients were evaluated clinically and radiographically (Knee Society scores). Knee Society scores improved from 25 preoperatively to 91 postoperatively, and function scores improved from 35 to 85. No loosening of implants was observed. Nonprogressive radiolucent lines were identified around 2 tibial components. One patient required a revision due to patellofemoral subluxation.
