Description
Summary:The management of patellae with a severe bony deficiency during revision total knee arthroplasty is a challenging problem. However, using a technique of augmentation with transcortical wiring of an onlay-type prosthesis allowed the authors to revise adefi cient patellae successfully. After making the decision to revise the existing patellar component, the procedure was found to betechnically straightforward. Furthermore, the procedure does not require sophisticated instruments, only an onlay-type prosthesis,cement and wires. This technique entails fi xing wires to the three pegs of the patellar component, passing the wires through drillholes in the anterior cortex and, after compression of a cemented prosthesis, augmenting the fi xation by twisting the wires anteriorly. We believe that stable fi xation and painless articulation will be obtained with the described technique for defi cient patellae. KCI Citation Count: 0
