Abstract
Realizamos un estudio retrospectivo descriptivo con un tamaño muestral de 121 pacientes sometidos a recambio protésico mediante la prótesis Legión® en nuestra área hospitalaria Vírgen del Rocío, Sevilla, desde mayo de 2008 hasta marzo de 2011. En este estudio reflejamos los datos epidemiológicos y los detalles técnicos realizados, evaluando el dolor postoperatorio, la movilidad y los resultados funcionales mediante el uso de escalas de valoración funcional y estudios radiográficos seriados. El seguimiento medio fue de 19 meses, con una edad media de 71 años y un 87% mujeres. Obtuvimos un media de 20,41º de balance articular ganados, corrección de deformidades previas consiguiendo restaurar el eje tibiofemoral al valgo anatómico; solventamos las pérdidas óseas previas al rescate y conseguimos realizar un adecuado balance de la interlínea articular. Un 66% de los pacientes permanecían sin dolor postoperatorio, siendo en el 33% restante de características leves-moderadas. Con respecto al dolor en la punta del vástago, no hemos encontrado relación significativa con el ángulo de incidencia del vástago sobre la cortical ni con el tipo de cementación. Obtuvimos una tasa del 74% de intervenciones sin complicaciones, siendo éstas una rotura del tendón rotuliano en un paciente, un caso de fractura periprotésica, dos arrancamientos iatrogénicos de TTA y siete infecciones (4 de ellas diagnosticadas previamente).
We carried out a descriptive, retrospective study with a sample side of 121 patients with Legión® prosthesis replacement in our Vírgen del Rocío hospital area, in the city of Seville, from May of 2008 until March of 2011. This study included epidemiological data as well as technical information about the process performed, including post-operative pain, mobility and functional results using a functional assessment scale and series of radiological studies. Average follow-up was 19 months, with a mean age of 71 years and 87% women. We obtained an average of 20.41º for articular balance obtained, correction of prior deformities by restoring the tibia-femoral axis to the anatomic e balance articular angle; we resolved bone loss prior to replacement and carried out an adequate balance of the inter-lineal joint. 66% of the patients continued with no post-operative pain, with the other 33% reporting slight to moderate pain. With regards to pain at the point of the stem, we have found no significant relationship with the incidence angle of the stem on the cortical or with the type of cement. We observed a 74% rate of intervention without complications, with complications being rupture of the patellar tendon in one patient, one case of peri-prosthesis fracture, two iatrogenic avulsion fractures of the anterior tibial tuberosity and seven infections (4 were diagnosed previously).
