    Over the last three decades, unicompartmental knee arthroplasty (UKA) has varied in its popularity. More recently the minimally invasive technique with improved instrumentation has resulted in a strong resurgence of interest in unicompartmental arthroplasty. Either in long term or short ones, UKA has shown excellent results specially if the surgeon follows the very delicate criteria for case selection. Even though it is a very demanding technique, the indications for UKA have expanded and only time will allow us to evaluate these changes. There is a significant learning curve in performing UKA through the minimally invasive technique. We report a case of recurrent dislocation of a mobile bearing polyethylene insert which required conversion to a total knee arthroplasty.Transcurridas las 煤ltimas tres d茅cadas, la artroplastia unicameral de rodilla (AUR) ha variado en popularidad y aceptaci贸n. Recientemente, la t茅cnica miniinvasiva con el avance de la nueva instrumentaci贸n, han logrado una fuerte reaparici贸n en el inter茅s de la artroplastia unicompartimental. Ya en largas o breves series, la AUR presenta excelentes resultados en especial si, el cirujano sigue escrupulosamente los criterios de selecci贸n de casos. Las indicaciones para la AUR han sido ampliadas y, 煤nicamente el tiempo nos facilitar谩 el poder evaluar estas variaciones. Hay una notoria curva de aprendizaje en la ejecuci贸n de la AUR a trav茅s de la t茅cnica miniinvasiva. Presentamos un caso de luxaci贸n recurrente de un platillo meniscal de polietileno m贸vil implantado, que precis贸 un recambio a una pr贸tesis total de rodilla
