Abstract
Purpose

To review the clinical and radiological results of a series of rotating platform knee arthroplasties with a follow-up of 6-12 years.

Materials and methods

This is a retrospective study of 133 arthroplasties implanted in our hospital between 1994 and 2001 using the original surgical technique. We applied the Knee Score and the Function Score of the American Knee Society in order to carry out the corresponding clinical assessment and radiological study.

Results

Six (4.5%) prostheses were totally or partially revised (2 cases of infection, 1 rotating platform spin out, one loosening of the tibial component, 1 instability and unidentifiable pain). Another 9 (6.7%) were operated without withdrawing any components (4 cases of soft tissue friction, one extra-articular infection, one femoral fracture, one bone calcification resection, one patellar prosthetization and one patellar fracture). All complications occurred before the third year. There was no component wear or any significant levels of osteolysis. Mean Knee and Function scores were very high: 90.6 and 86.5 respectively.

Conclusions

Clinical-radiographic medium- to long-term results for this rotating platform prosthetic design are highly satisfactory, albeit at the expense of a slight increase in the number of early complications.

Resumen
Objetivo

revisar los resultados clínicos y radiológicos de una serie de artroplastias de rodilla con plataforma rotatoria con un seguimiento de 6 a 12 años.

Material y método

estudio retrospectivo de 133 artroplastias intervenidas en nuestro centro, entre 1994 y 2001, mediante la técnica quirúrgica original. Aplicamos el Knee Score y Function Score de la American Knee Society para su valoración clínica y el estudio radiológico correspondiente.

Resultados

en 6 (4,5%) prótesis se realizó recambio total o parcial, 2 por infección, otra por luxación de la plataforma rotatoria, una por aflojamiento del componente tibial, una por inestabilidad y otra por dolor de causa incierta. En otras 9 (6,7%) se intervino sin retirar los componentes: 4 por fricción de partes blandas, una infección extraarticular, una fractura de fémur, una resección de calcificación ósea, una protetización de rótula y una fractura de rótula. Todas las complicaciones tuvieron lugar antes del tercer año. No hubo desgaste de los componentes ni osteólisis importantes. La puntuación media para la rodilla y la función fue muy alta (90,6 y 86,5).

Conclusiones

los resultados clínico-radiográficos a medio-largo plazo de este diseño protésico con plataforma rotatoria son muy satisfactorios, aunque a costa de un discreto incremento de complicaciones precoces.
