چکیده انگلیسی

Objectivesthe aim of this study was to evaluate the surgical technique and determine the initial results, with a minimum follow-up of two years, from total knee arthroplasty revisions in which trabecular metal cones made of tantalum were used at the Knee Surgery Center of the National Institute of Traumatology and Orthopedics (INTO) or at the authors’ private clinic between July 2008 and December 2010.Methodsten patients were included in the study prospectively, through clinical and radiographic evaluations.Resultsseven patients presented evolution without complications relating to the tantalum cones used. Five of these patients said that they did not have any pain and all of them were able to walk without needing crutches. In all the cases, we observed that osseointegration of the tantalum cones had occurred. No migration or loosening of the implants was observed, nor was osteolysis.Conclusionuse of trabecular metal cones made of tantalum for treating AORI type II or II bone defects was capable of providing efficient structural support to the prosthetic revision implants, in evaluations with a short follow-up.

ResumoObjetivosavaliar a técnica cirúrgica e determinar os resultados iniciais, com seguimento mínimo de dois anos, das revisões de artroplastia total do joelho nas quais cones de metal trabecular tântalo foram empregados pelo Centro de Cirurgia do Joelho do Instituto Nacional de Traumatologia e Ortopedia (Into) ou na clínica privada dos autores de julho de 2008 a dezembro 2010.Métodosforam incluídos no estudo 10 pacientes, prospectivamente em avaliação clínica e radiográfica.Resultadossete pacientes apresentaram evolução sem complicações relacionadas ao uso de cones de tântalo, cinco negam dor e todos deambulam sem necessidade de muletas. Em todos os casos, verificamos osteointegração dos cones de tântalo e não foi observada migração ou soltura de implantes, assim como osteólise.Conclusãoo uso de cones de metal trabecular tântalo para tratamento de defeitos ósseos tipo II ou III Aori apresenta-se capaz de prover suporte estrutural eficiente aos implantes protéticos de revisão em avaliação de curto seguimento.
