Artroplastia total de rodilla no cementada

Abstract

Interest for uncemented total knee arthroplasty (TKA) has greatly increased in recent years. As the number of younger and more active patients treated with TKA continues to increase, consideration of better fixation as a means of improving implant longevity is required. This technique, less used than cemented knee replacement in the last decades, sees a revival thanks an advance in prosthetic design, instrumentation and operative technique. The related literature in some cases shows conflicting data on survival and on the revision’s rate, but in most cases a success rate comparable to cemented TKA is reported. Noncemented components offer the potential advantage of a biologic interface between the bone and implants, which could demonstrate the greatest advantage in long-term durable fixation in the follow-up of young patients undergoing arthroplasty. The optimal fixation in TKA is a subject of debate with the majority of surgeons favouring cemented fixation. Although longterm, high-quality studies are still needed, material advances in biologic fixation surfaces, such as trabecular metal and hydroxyapatite, may offer promising results 232 . 2019; 15 (4): 231-238 www.medigraphic.org.mx www.medigraphic.org.mx riales en las superficies de fijación biológica, como el metal trabecular y la hidroxiapatita, pueden ofrecer resultados prometedores para pacientes jóvenes y activos sometidos a artroplastia total de rodilla en comparación con las opciones cementadas tradicionales. Realizamos una revisión de la literatura que evalúa los avances de ATR no cementada y los resultados reportados.
