RESUMO

INTRODUCTION: Classically the results of any joint replacement surgery are evaluated at a minimum of 5 years. This period could be considered excessive to evaluate the functional results of this procedure. The objective of this study is to compare functional and quality of life results to 1 and five years of follow-up following a total knee replacement (TKR). MATERIAL AND METHODS: Prospective observational study. All patients visited one year after the implantation of TKR were included. All of these filled out the SF-36 questionnaire and the KSS valuation scale. Both were administered again at age five after surgery. RESULTS: 689 patients were initially included in the study (163 men [23.7%] and 526 women [76.3%]) with an average age of 72.2 years. At age 5,585 (84.9%) of these patients were re-analyzed. While the knee section of the KSS scale remained similar in these two periods, the function section of the KSS titration scale showed a slight worsening over time (p = 0.008). With respect to SF-36, the physical summation worsened at five years (p = 0.00) and the mental summation remained stable (n.s.) between the year and five years after surgery. DISCUSSION: Five years after a TKR, the physical exam does not vary from the year of surgery. However, the subjective evaluation measured by the function-KSS section and the physical SF-36, worsen slightly during this period. This could be due to aging patients.


INTRODUCCIÓN: Clásicamente los resultados de cualquier cirugía de reemplazo articular se evalúan en un mínimo de cinco años. Este período podría considerarse excesivo para evaluar los resultados funcionales de este procedimiento. El objetivo de este estudio es comparar los resultados funcionales y de calidad de vida a uno y cinco años de seguimiento tras una artroplastía total de rodilla (ATR). MATERIAL Y MÉTODOS: Estudio prospectivo observacional. Se incluyeron todos aquellos pacientes visitados un año después de la implantación de una ATR. Todos ellos rellenaron el cuestionario SF-36 y la escala de valoración KSS. Ambos fueron administrados nuevamente al cabo de cinco años de la cirugía. RESULTADOS: 689 pacientes fueron incluidos inicialmente en el estudio (163 hombres [23.7%] y 526 mujeres [76.3%]) con una edad media de 72.2 años. A los cinco años, 585 (84.9%) de estos pacientes fueron analizados de nuevo. Mientras que la sección rodilla de la escala KSS se mantenía similar en estos dos períodos, la sección función de la escala de valoración KSS mostraba un leve empeoramiento con el tiempo (p = 0.008). Con respecto al SF-36, el sumatorio físico empeoraba a los cinco años (p = 0.00) y el sumatorio mental se mantenía estable (n.s.) entre un año y cinco años tras la cirugía. DISCUSIÓN: Después de cinco años de una ATR, el examen físico no varía con respecto al año de la cirugía. Sin embargo, la evaluación subjetiva medida mediante la sección función-KSS y el SF-36 físico empeoran ligeramente durante este período. Esto podría ser debido al envejecimiento de los pacientes.

RESUMO

BACKGROUND: The purpose of this study was to analyze the clinical and radiological evolution of the total knee revision arthroplasty with cemented stems in patients over 75 years. MATERIAL AND METHODS: A retrospective analysis was performed in all the subjects who underwent revision of total knee arthroplasty with cemented stems between 2008 and 2014 in our center. Twenty-seven individuals over 75 years met the inclusion criteria. We assessed the Knee Society Score and range of motion for clinical outcome. We evaluated the implant stability with radiographs through radiolucent lines according to the modified radiological scale of the Knee Society; we registered the complications and prosthetic survival. RESULTS: With an average age of our participants of 82.6 ± 4.4 years and a follow-up of 43 ± 14.4 months, we did not find any mechanical failure of the components. The functional average score was 115 ± 32 in the total KSS, of which 77 ± 17.5 points were in the KSS knee and 42 ± 24 in the KSS function. The average range of motion was 98º ± 17. Radiologically, 18 patients presented radiolucent lines, but only three needed follow-up using the modified Knee Society radiographic scoring system. CONCLUSIONS: The results revealed that cemented stems are a good method for fixation in the revision of total knee arthroplasty in people over 75 years. We observed acceptable medium-term clinical results with a low risk of radiological failure, despite the high number of radiolucencies.

RESUMO

Resumen: Antecedentes: Analizar la evolución funcional y radiológica de los pacientes mayores de 75 años intervenidos de cirugía de revisión de rodilla con vástagos cementados. Material y métodos: Mediante análisis retrospectivo, hemos revisado a 27 individuos mayores de 75 años a quienes se les ha implantado una prótesis total de rodilla de revisión con vástagos cementados en nuestro centro entre 2008-2014. Durante el seguimiento, se realizó un análisis clínico mediante la escala Knee Society Score y de movilidad de la rodilla, un análisis radiológico de la estabilidad de los implantes por medio de la escala radiológica modificada de la Knee Society, el registro de las complicaciones y la supervivencia protésica. Resultados: Con una edad media de los participantes de 82.6 ± 4.4 años y un seguimiento medio de 43 ± 14.4 meses, no hemos observado ningún caso de aflojamiento mecánico de los componentes. La valoración funcional ha sido de 115 ± 32 puntos en la escala total KSS, de los cuales 77 ± 17.5 puntos pertenecen al KSS rodilla y 42 ± 24 puntos al KSS función. El rango medio de movilidad fue de 98o ± 17. A nivel radiológico, 18 sujetos mostraron radiolucencias periprotésicas; según los criterios de la escala radiológica de la Knee Society, solo tres requirieron seguimiento clínico-radiológico estricto. Conclusiones: La cementación de los vástagos en prótesis totales de rodilla de revisión se trata de un buen sistema de fijación en personas mayores de 75 años, con elevada supervivencia del implante, buen resultado funcional y bajo porcentaje de aflojamiento radiológico a pesar de la aparición frecuente de radiolucencias.

RESUMO

Isolated long bone fractures are unusual and may be missed in the initial X-rays, especially when they are minimally displaced. The delayed treatment of these fractures may cause various complications, such as delayed bone healing or seudoarthrosis, which are difficult to manage. Our clinical case shows delayed healing in a long bone fracture and how the radiologic course may assist in the therapeutic management of this complication.
