ABSTRACT

Introducción: la reconstrucción del Ligamento Cruzado Anterior (LCA) con isquiotibiales resistiría 1216 N, con una pérdida extensora de sólo un 3%. Nuestro objetivo es revisar nuestra experiencia con este procedimiento con el sistema Aperfix®. Material y métodos: Estudio observacional, descriptivo y retrospectivo. Tamaño muestral de 224 casos, seguimiento mínimo de 12 meses. Analizamos entre otros: filiación, movilidad, R.N.M., tiempo quirúrgico y escala Lysholm. Analizamos diferencias estadísticas entre el abordaje femoral desde el portal anteromedial o desde el túnel tibial, mediante los test t de Student, U de Mann Whitney y Chi Cuadrado, con S.P.S.S. 20.0. Resultados: Edad media de 36.5 ± 8.7 años, Lachmann previo en el 96.8% y Pívot Shift previo positivo en el 51.4%, lesiones meniscales asociadas en el 73.8%. Tiempo quirúrgico: 87.1± 18.9 minutos, Lachmann postquirúrgico en el 17.4% y Pívot Shift negativo en el 98.9%. Flexión final de 128.1 ± 5.2°, 95.8 ± 7 puntos de escala final de Lysholm. Complicaciones en el 11%. Altas por mejoría en el 98.9%. No hallamos diferencias significativas entre ambas formas de realización del túnel femoral. Sólo con respecto al tiempo quirúrgico, p=0.004, siendo éste algo mayor cuando se realizada desde el portal anteromedial. Conclusiones: En nuestra experiencia, la ligamentoplastia con el sistema Aperfix® mejora la escala Lysholm, con escasas complicaciones y buen resultado funcional. No hallamos grandes diferencias en cuanto a la realización del túnel femoral, sólo un mayor tiempo quirúrgico cuando se realiza desde el portal anteromedical.


Introduction: reconstruction of the anterior cruciate ligament (A.C.L.) with hamstring grafts would resist 1216 N, with an extensor loss of only 3%. Our goal is to review our experience with this procedure with the Aper x® system. Material and methods: Observational, descriptive and retrospective study. Sample size of 224 cases, minimum followup of 12 months. We analyzed among others: liation, mobility, M.R.I., surgical time and Lysholm’s scale. We analyzed statistical differences between femoral approach from anteromedial portal or from tibial tunnel, using the Student t, Mann Whitney U and Chi Square tests, with S.P.S.S. 20.0. Results: Mean age was 36.5 ± 8.7 years, Lachmann’s test previous surgery was positive in 96.8% and Pivot Shift in 51.4%. There were associated meniscal injuries in 73.8%. Surgical time was 87.1 ± 18.9 minutes. Post-surgical Lachmann’s test was positive at 17.4% and post-surgical Pivot Shift was negative at 98.9%. Final exion was 128.1 ± 5.2°, with 95.8 ± 7 points at Lysholm’s scale. There were complications in 11%. 98.9% of patients returned to their previous jobs. We did not nd signi cant differences between both forms of femoral tunneling. Only with respect to surgical time, p = 0.004, it was longer for cases operated by means of anteromedial portal. Conclusions: In our experience, ligamentoplasty with the Aper x® system improves Lysholm’s scale, with a few complications and good functional outcome. We do not nd great differences in performance of femoral tunnel, only a longer surgical time when it was performed from the anteromedial portal.
