espanolObjetivo Descripcion de una nueva osteotomia coronal de la faceta externa de la rotula y valorar si los resultados del tratamiento del sindrome de compresion lateral de la rotula (SCLR) con nuestra osteotomia junto a la liberacion del retinaculo lateral externo son mejores que la liberacion aislada del retinaculo lateral. Material y metodos Estudio prospectivo con 2 anos de seguimiento, donde tratamos 70 pacientes diagnosticados de SCLR y distribuidos en 2 grupos: un primer grupo de 50 pacientes en los que se realizo la liberacion del retinaculo lateral asociada a osteotomia, y un segundo grupo de 20 pacientes en los que se realizo una liberacion aislada del retinaculo lateral. Se midio la escala funcional de Werner de forma preoperatoria y a los 3, 12 y 24 meses. Resultados Existen diferencias significativas en el estado funcional global postoperatorio entre grupos (mejor el grupo de osteotomia en todos los intervalos, p Conclusion Los resultados muestran que la tecnica de osteotomia rotuliana descrita asociado a la liberacion del retinaculo lateral mejora de forma significativa el dolor y la escala funcional de pacientes con SCLR a los 2 anos de seguimiento, en mayor grado que lo hace la liberacion aislada del retinaculo lateral, incluso en aquellos en los que existe evidencia de signos degenerativos. EnglishObjective To describe a novel coronal osteotomy of the external facet of the patella, and to evaluate if the outcomes of the treatment of lateral knee compartment syndrome (LKCS) with this osteotomy, combined with the release of the external lateral retinaculum, are better than the isolated lateral retinacular release. Material and methods A prospective study with a 2 year follow up that included 70 patients diagnosed with LKCS, distributed into 2 groups. The first group included 50 patients on whom the lateral retinacular release combined with osteotomy was performed, and a second group on whom an isolated retinacular release was performed. Measurements were made using the Werner functional scale before the surgery and at 3, 12, and 24 months follow-up. Results There were significant differences in the overall functional state between the two groups after the surgery (better in the osteotomy group at all the intervals, P Conclusion The results demonstrate that the described patellar osteotomy technique, combined with lateral retinacular release, significantly improves the pain and the functional scale score of patients with LKCS after 2 years of follow-up, to a greater extent than isolated lateral retinacular release, including those in which there was evidence of degenerative signs.
