Resumen Antecedentes y objetivos El objetivo de este estudio es evaluar que factores pueden influir en la supervivencia de la artroscopia de cadera a medio plazo en el contexto de patologia degenerativa. Material y metodos Llevamos a cabo un estudio retrospectivo de 40 casos de una serie de 102 pacientes intervenidos de artroscopia de cadera en nuestro centro, desde agosto de 2007 a octubre de 2011. Al final del seguimiento, todos los pacientes cumplimentaron tres escalas funcionales: Hip Outcome Score-Activites of Daily Life (HOS-ADL), Hip Outcome Score-Sport (HOS-S) y Harris Hip Score modificado (HHSm). Resultados Finalmente se incluyo un total de 39 pacientes (40 caderas), con una edad media de 43,1 anos y un tiempo de seguimiento medio de 6 anos (43-130 meses). Los pacientes intervenidos con una edad inferior a 50 anos obtuvieron mejor puntuacion en las escalas HOS-S (25,2 puntos) y HHS-m (84,1 puntos) en comparacion con aquellos intervenidos a partir de dicha edad (HOS-S [25,2 puntos]; HHS-m [84,1 puntos]). El tiempo de evolucion tambien influyo significativamente en el resultado de nuestros pacientes, siendo mejor en aquellos en los que este era menor a 12 meses (26,6 meses), en comparacion con aquellos en los que era mayor (21,3 meses). Por otro lado, aquellos que presentaban una intervencion quirurgica lumbar previa obtuvieron peores resultados de HOS-ADL (49,3 puntos), respecto a aquellos que no presentaban este antecedente (56,5 puntos). El Patient acceptable symptom state (PASS) fue superado por 23 pacientes (57,5%), 22 pacientes (55%) y 25 pacientes (62,5%) en las escalas HHSm, HOS-ADL y HOS-S respectivamente. Ningun paciente presento ninguna complicacion mayor. Cuatro pacientes presentaron complicaciones menores. La supervivencia media obtenida fue de 97,1 meses (IC 95%, 85,1-109,1 meses), asociado con un 81% de pacientes (IC 95%, 69%-93%) que no preciso rescate quirurgico a los 10 anos. Conclusiones Creemos que los datos obtenidos en nuestra serie sugieren que la artroscopia de cadera en el contexto de patologia degenerativa es una intervencion quirurgica segura con un resultado funcional fiable a corto-medio plazo. Por otro lado, dicha indicacion deberia hacerse con mayor precaucion en pacientes sometidos previamente a cirugia lumbar. Nivel de evidencia Nivel IV. Serie de casos.

Background and purpose The purpose of this study is to identify which variables may have a significant impact in mid-term survivorship following hip arthroscopy. Methods This a single-centre single-surgeon retrospective study including 102 patients who underwent a hip arthroscopy procedure between August 2007 and October 2011. Each subject completed three questionnaires at final follow- up: “Hip "Outcome Score-Activities of Daily Living" (HOS-ADL), "Hip Outcome Score-Sport" (HOS-S) and " Modified Harris Hip Score “(m-HHS). Results Thirty-nine patients (40 hips) were finally included in our study. Mean age was 43.1 ± 9.9 years with a three-year minimum follow-up (75.43 ± 25.2 months). Younger patients and those with a shorter duration of symptoms obtained significantly higher HOS-S and m-HSS scores. Patients who had undergone previous lumbar spinal surgery obtained significantly worse HOS-ADL scores. Patient acceptable symptom state (PASS) was achieved in 23 patients (57.5%) for m-HHS, 22 patients (55%) for HOS-ADL and 25 patients for HOS-S scores. No major complication was observed. Only four patients had minor complications. Mean survival time was 97.1 months (95% CI, 85.1–109.1 months), with a survival at 8 years of 69% (95% CI, 53%–85%). Conclusions Our findings suggest that hip arthroscopy is a safe procedure with acceptable functional outcomes after a long follow-up. Care should be taken when treating patients with prior lumbar surgery. Level of evidence Level IV. Case series.
