La cirugía artroscópica de cadera en deportistas varones menores de 40 años con choque femoroacetabular: resultado a corto plazo / Hip arthroscopy in males younger than 40 with femoroacetabular impingement: short-term outcomes

Introducción y objetivos. El choque femoroacetabular es el mecanismo más común descrito en la literatura que conduce a la lesión del labrum y del cartílago articular en la cadera no displásica. Nuestro objetivo fue determinar los resultados clínicos y radiológicos de la cirugía artroscópica de cadera como tratamiento del choque femoroacetabular en pacientes jóvenes con alta demanda funcional. Material y métodos. Estudio prospectivo de 41 pacientes menores de 40 años tratados mediante cirugía artroscópica de cadera por choque femoroacetabular. Para valoración clínica se utilizaron la escala modificada de Harris, cuestionarios de valoración HOS e IHOT12. Se realizó una valoración radiológica para determinar altura articular y ángulo alfa. Resultados. La edad media de los pacientes fue de 32,7 años. Se detectó lesión del labrum en el 78% y del cartílago acetabular en el 56% de los casos. El seguimiento medio de los pacientes fue de 31,3 meses. Hubo una mejora significativa en la puntuación media en los cuestionarios de valoración clínica. Radiológicamente no se modificó la altura media del espacio articular, con reducción significativa a valores normales del ángulo alfa. Todos los pacientes se reincorporaron a su actividad deportiva habitual previa. Discusión. La cirugía artroscópica de cadera ha permitido la mejoría clínica de los pacientes con corrección de la deformidad ósea, lesión labral y cartilaginosa, y reincorporación de los pacientes a sus actividades deportivas previas a la cirugía. Es fundamental un mayor seguimiento para confirmar la estabilidad de los resultados clínicos y radiológicos obtenidos (AU)

Introduction and objectives. Femoroacetabular impingement is probably the most common mechanism that leads to the development of early cartilage and labral damage in the non-dysplastic hip. The objective was to evaluate the outcomes of hip arthroscopy as a treatment for femoroacetabular impingement in patients with high level of function. Material and methods. A prospective study was performed on 41 patients younger than 40 years old undergoing hip arthroscopy for femoroacetabular impingement. Modified Harris Hip Score and HOS and IHOT questionnaires were used for clinical assessment. Radiological evaluation was made for joint space and alpha angle. Results. The mean age of patients was 32.7 years. Labrum injury was detected in 78%, and acetabular cartilage injury in 56% of cases. The average follow-up was 31.3 months. There was a significantly improvement in the mean score in the clinical questionnaires. Radiologically there was no change in the mean joint space, with significantly reduction to normal values of the alpha angle. All patients returned to sports at their pre-injury level of function. Discussion. Hip arthroscopy resulted in improvement in hip functional outcomes with correction of the underlying osseous deformity and treatment of the associated labral and cartilage pathology, with the return of patients to their pre-injury sports. Further follow-up is essential to confirm the stability of the clinical and radiological outcomes (AU)

INTRODUCTION AND OBJECTIVES: Femoroacetabular impingement is probably the most common mechanism that leads to the development of early cartilage and labral damage in the non-dysplastic hip. The objective was to evaluate the outcomes of hip arthroscopy as a treatment for femoroacetabular impingement in patients with high level of function. MATERIAL AND METHODS: A prospective study was performed on 41 patients younger than 40 years old undergoing hip arthroscopy for femoroacetabular impingement. Modified Harris Hip Score and HOS and IHOT questionnaires were used for clinical assessment. Radiological evaluation was made for joint space and alpha angle.

DISCUSSION: Hip arthroscopy resulted in improvement in hip functional outcomes with correction of the underlying osseous deformity and treatment of the associated labral and cartilage pathology, with the return of patients to their pre-injury sports. Further follow-up is essential to confirm the stability of the clinical and radiological outcomes.
