Outcome of 4-strand semitendinosus-gracilis anterior ligament reconstruction in women: A matched-cohort study. / Resultados a 3 años tras técnica de reconstrucción anatómica semitendinoso-recto interno 4 fascículos del ligamento cruzado anterior en las mujeres: estudio de casos y controles.

INTRODUCTION: Women carry out a greater risk of anterior cruciate ligament (ACL) rupture. However, outcomes following ACL reconstruction remain unclear. The aim of this study was to analyze the outcomes in women following ACL reconstruction and compare these outcomes with men. MATERIAL AND METHODS: Retrospective study of a prospective database of patients treated with ACL reconstruction between January 2017 and December 2018. Outcome measures included Tegner activity scale, Lysholm scale, EVA scale, and IKDC evaluation form. Clinical significance was measured with minimally clinical important difference, and patient acceptable symptom state. RESULTS: A total of 33 women were matched with 99 men. The mean follow-up was 36 months. Women showed significant improvement from preoperative PROs to the latest follow-up, with no differences between groups. In patients under 25 years old, there was less significant IKDC subjective score in women compared to men. There were no significant differences in frequency of patients achieving MCID and PASS in women compared with men. CONCLUSIONS: At 3-year following 4-strand semitendinosus-gracilis anterior ligament reconstruction, women showed significant improvements in PROs, with no differences compared to men.

Psychological readiness to return to sports after anterior cruciate ligament reconstruction in amateur sport. / Preparación psicológica para la reincorporación deportiva tras cirugía reconstructiva del ligamento cruzado anterior en el deportista aficionado.

INTRODUCTION: Return to sports (RTS) is maybe the main expectation for the patient after anterior cruciate ligament reconstruction (ACLR). The aim of this study was to analyze the psychological readiness to RTS in a cohort of amateur sports after ACLR. MATERIAL AND METHODS: Retrospective study of a prospective database of patients treated with ACLR performed between January and December 2017. Psychological readiness to RTS after ACLR was evaluated with the short version of the Anterior Cruciate Ligament Return to Sport After Injury (ACL-RSI) scale. RESULTS: A total of 43 patients met the inclusion criteria. The mean age of the patients was 24.7 years. The mean follow-up was 32.5 months. All patients practiced any type of sports at final follow-up. The mean ACL-RSI score was 71.5. Fear of reinjury was mentioned by 14 patients (32.5%). Twenty-four patients (55.8%) pointed out that they did not practice sport at the pre-injury level. The mean ACL-RSI score was statistically significant lower in this group of patients (59.7 vs 87.3; P<.001). CONCLUSIONS: Fear of reinjury keeps after ACLR. Patients that they did not practice sport at the pre-injury level show lower scores in ACL-RSI for RTS.

[Results of arthroscopic treatment of rotator cuff rupture in patients over 60 years of age]. / Resultados del tratamiento artroscópico de la rotura del manguito rotador en pacientes mayores de 60 años.

INTRODUCTION: Increasing life expectancies in population increase the number of patients with rotator cuff tears. The purpose of this study was to evaluate clinical outcomes after arthroscopy rotator cuff repair in patients over 60 years old. We hypothesized that shoulder arthroscopy would allow significant improvements in clinical outcomes without serious complications. MATERIAL AND METHODS: We screened from our shoulder arthroscopy database patients older than 60 years old, with rotator cuff tear, and minimun 2-year follow-up. The patients were evaluated using Constant scores for clinical outcomes and Quick-DASH score for quality of life. RESULTS: In total, 42 patients were enrolled in the study with a mean age of 66.7 years old (range 60 to 83). A double-row repair was indicated in 25 patients (59.5%), and single-row repair in 17 patients (40.5%). As associated injuries we found proximal biceps pathology in 31 patients (48.4%), subscapularis tears in 24 patients (37.5%), and SLAP tears in 3 patients (7.1%). Mean follow-up was 32.4 months. Constant scores improved from 48.3 preoperatively to 87.2 at final follow-up. Quick-DASH decreased from 52.5 preoperatively to 11.0 at final follow-up. DISCUSSION: Arthroscopy cuff repair in patients older than 60 years old provides satisfactory clinical outcomes without morbidity at medium follow-up.

Estudio de cohortes comparativo del abordaje Superpath con abordaje convencional posterior en cirugía protésica primaria de cadera no cementada: curva de aprendizaje y resultados a corto plazo / Comparative cohort study of the SuperPath approach and the conventional posterior approach in primary cementless hip replacement surgery

Antecedentes y objetivo: En la actualidad no existe un consenso sobre cuál es el mejor abordaje de cadera para implantar una prótesis. Sin embargo, sí existe una tendencia a reducir al máximo la lesión sobre los tejidos periarticulares, lo cual puede influir en los resultados a corto plazo. El abordaje Superpath permite el acceso a la articulación manteniendo la integridad de los rotadores externos. El objetivo de nuestro estudio fue comparar los resultados a corto plazo del abordaje Superpath con el abordaje convencional posterior. Materiales y métodos: Estudio prospectivo de cohorte de 30 pacientes intervenidos mediante abordaje Superpath pareados por sexo, edad, índice de masa corporal y valoración clínica, con 60 pacientes intervenidos mediante abordaje convencional posterior. La valoración clínica se realizó mediante la escala de Harris, Merle d'Aubigné, Womac para el dolor y la función, SF-12 físico y mental, HOS-AVD e IHOT-12. Radiológicamente se determinó el ángulo de inclinación acetabular, alineación del vástago femoral e integración de los implantes. Resultados: No hubo diferencias significativas entre ambas cohortes con respecto a las variables preoperatorias. El tiempo quirúrgico, el descenso medio de Hb y Hto y la pérdida sanguínea fue mayor en la cohorte Superpath. La estancia hospitalaria fue similar. Los cuestionarios de valoración clínica mostraron incrementos significativos entre los valores preoperatorios y a los 12 meses en ambas cohortes. El cuestionario IHOT-12 a los 3 meses, el cuestionario SF-12 físico y el cuestionario SF-12 mental a los 12 meses, mostró mayores puntuaciones en la cohorte Superpath, siendo las diferencias significativas. Radiológicamente no se detectaron diferencias entre ambas cohortes. Conclusiones: La curva de aprendizaje del abordaje Superpath presenta unos resultados clínicos y radiológicos similares al abordaje posterior durante el primer año tras la prótesis total de cadera. A destacar la necesidad de un mayor tiempo quirúrgico y un mayor sangrado en los pacientes

Background and objectives: There is no current consensus on the most suitable hip approach. However, there is a trend to reduce damage to soft tissue, which may have an influence on early outcomes. The SuperPath approach accesses the capsule maintaining integrity of the external rotators. The purpose of this study was to compare the SuperPath approach with the conventional posterior approach, in terms of early outcomes and radiological results. Material and methods: A cohort of 30 patients operated using the SuperPath approach was prospectively matched for age, gender, body mass index and hip function with 60 patients operated using a conventional posterior approach. Clinical evaluation was performed by the Harris score, Merle d'Aubigné score, reduced Western Ontario and McMasters Universities (WOMAC), Short-Form 12 (SF12), IHOT-ADV and IHOT-12 questionnaires. Radiological evaluation was also performed. Results: Preoperatively, no significant differences were detected between cohorts. Skin-to-skin operation time and blood loss was higher in the SuperPath cohort. Length of stay was similar between cohorts. Clinical evaluation improved significantly from the preoperative values to the 1-year follow-up. At 3 months the SuperPath cohort showed better results for IHOT-12, and at 12 months for SF. Radiologically, there were no differences between cohorts. Conclusion: This prospective randomized study reveals that the learning curve for the SuperPath approach provides similar outcomes to the conventional posterior approach within the first year after surgery. The Superpath approach was associated with longer skin-to-skin operation time, and greater blood loss

Arthroscopic hip surgery with a microfracture procedure of acetabular full-thickness chondral damage. Cohort study with a 3-year follow-up. / Tratamiento artroscópico mediante microfracturas de la lesión cartilaginosa acetabular de espesor completo. Estudio de cohortes con seguimiento medio a 3 años.

INTRODUCTION AND PURPOSE: Management of injuries to the articular cartilage is complex and challenging. Our purpose was to assess outcomes of a cohort of patients who underwent hip arthroscopy with full-thickness chondral damage treated with microfracture and compare these outcomes with those from a similar cohort of patients who did not. MATERIAL AND METHODS: We prospectively gathered the data of 31 hips treated with microfracture from January 2009 to January 2016. In the cohort of hips without chondral damage there were 49 hips. All patients were assessed pre- and postoperatively with 4 patient-reported outcome instruments. RESULTS: The mean follow-up was 36.2 months in the cohort of patients with full-thickness chondral damage, and 36.6 months in the cohort of patients without chondral damage. Both groups demonstrated significant improvement in all patient-reported outcome instruments between preoperative and final follow-up. There was no statistically significant difference between both cohorts at final follow-up. DISCUSSION: This study showed that patients undergoing microfracture during hip arthroscopy had significant improvement in all patient-reported outcome instruments during follow-up. The greatest improvement was noted at 6 months postoperatively. Both groups showed no significant difference in final patient-reported outcome instruments scores.

Rigidez postraumática de codo: resultados a corto plazo de la artrólisis artroscópica / Post-traumatic elbow stiffness: arthroscopic release, short-term results

Resumen: Antecedentes: La «artrólisis¼ abierta ha sido el tratamiento estándar en la rigidez de codo, con buenos resultados; sin embargo, las complicaciones asociadas y los avances en la cirugía artroscópica han permitido incorporar esta técnica quirúrgica. Material y métodos: Entre Enero de 2014 y Marzo de 2016, seis pacientes con rigidez postraumática de codo fueron intervenidos mediante cirugía artroscópica por el mismo equipo quirúrgico. Se registró pre- y postoperatoriamente, el nivel de dolor según escala analógica visual numérica, rango de movilidad articular del codo con el uso de un goniómetro y cuestionario Mayo Elbow Performance Index. Resultados: El seguimiento medio de los pacientes fue de 14.5 meses. El valor medio en la escala analógica visual disminuyó de 4.5 a 0.3 puntos. El rango medio de movilidad del codo se incrementó de 55.3o a 130o, con una ganancia media de 75o. La puntuación media en el cuestionario MEPI pasó de 46.6 puntos a 95 puntos, con una ganancia media de 48.4 puntos. Como procedimientos asociados a la «artrólisis¼ artroscópica se realizó extracción del material de síntesis en las tres fracturas de olécranon. No hubo ningún caso de osificación heterotópica, infección superficial o neuropatía cubital. Ningún paciente precisó reintervención quirúrgica para una nueva «artrólisis¼ artroscópica o abierta. Conclusiones: La liberación artroscópica en la rigidez postraumática de codo es una técnica efectiva a corto plazo para recuperar la movilidad.

Abstract: Background: Open «arthrolysis¼ has been the standard treatment for elbow stiffness, with good results. However, the associated complications of open arthrolysis and the advancements in arthroscopic surgery have allowed including the latter as an additional approach. Material and methods: Between January 2014 and March 2016, 6 patients with posttraumatic elbow stiffness underwent arthroscopic surgery by the same surgical team. Pre- and post-operative assessment included pain with a numerical visual analogue scale, elbow joint range of motion with a goniometer and the Mayo Elbow Performance Index questionnaire. Results: Mean patient follow-up was 14.5 months. The mean VAS score decreased from 4.5 to 0.3. The mean elbow range of motion increased from 55.3o to 130o, with a mean gain of 75o. The mean MEPI questionnaire score went from 46.6 to 95, with a mean gain of 48.4 points. The procedures associated with arthroscopic «arthrolysis¼ included removal of the synthesis material from the 3 olecranon fractures. No cases of heterotopic ossification, superficial infection or ulnar neuropathy were reported. None of the patients required surgical reintervention to perform a new «arthrolysis¼, whether arthroscopic or open. Conclusions: Arthroscopic release to treat posttraumatic elbow stiffness is an effective technique to restore mobility in the short term.

Lesión cartilaginosa del reborde acetabular en estadios Tönnis 0 y 1: incidencia, grado, localización y factores preoperatorios asociados / Tönnis stage 0 and 1 acetabular rim cartilage injuries: incidence, grade, location and associated pre-surgical factors

Introducción y objetivo. La presencia de lesión cartilaginosa condiciona en gran medida el resultado funcional de cualquier articulación tras el tratamiento quirúrgico. Nuestro objetivo fue determinar la prevalencia, localización, grado y factores preoperatorios asociados a la lesión cartilaginosa del reborde acetabular en pacientes intervenidos mediante cirugía artroscópica de cadera. Material y métodos. Estudio prospectivo de los hallazgos intraoperatorios en 152 caderas de 122 pacientes consecutivos intervenidos mediante cirugía artroscópica de cadera por choque femoroacetabular entre enero de 2011 y mayo de 2016. Se determinó la prevalencia, localización, grado, y factores preoperatorios asociados a la lesión cartilaginosa del reborde acetabular. Resultados. La edad media de los pacientes fue de 36,8 años. El grado de degeneración articular era Tönnis 0 en 103 caderas y Tönnis 1 en 52 caderas. En 109 caderas (70,3%) se detectó lesión cartilaginosa del reborde acetabular. La localización de las lesiones fue superior y anterior. El análisis estadístico estableció como factores preoperatorios independientes para la presencia de lesión cartilaginosa del reborde acetabular un ángulo alfa igual o mayor de 55°, un tiempo de evolución de los síntomas hasta la artroscopia igual o mayor de 20 meses, y un nivel de actividad física en la escala de Tegner igual o mayor de 6. Discusión. A pesar de que los pacientes se clasificaron como Tönnis 0 y 1, y que la resonancia nuclear magnética de 3tesla informó de la presencia de lesión cartilaginosa en el 1,3% de los casos, existía una alta frecuencia de lesiones cartilaginosas del reborde acetabular. El conocimiento de los factores predictores preoperatorios asociados a la lesión cartilaginosa del reborde acetabular puede ayudar al cirujano ortopédico sobre la indicación de la cirugía artroscópica de cadera (AU)

Introduction and purpose. Articular cartilage lesions have a direct effect on the success of surgical treatment. The aim of this study was to determine the prevalence rate, location, grade, and factors associated with acetabular rim articular cartilage lesions in patients undergoing hip arthroscopy. Material and methods. A prospective study was conducted by analysing the intraoperative data of 152 hips in 122 patients treated with hip arthroscopy for femoroacetabular impingement from January 2011 to May 2016. The prevalence rate, location, and grade were calculated, as well as the pre-operative factors associated with acetabular rim articular cartilage lesions. Results. The mean age of the patients was 38.6 years. The Tönnis grade was 0 in 103 hips, and 1 in 52 hips. Acetabular rim articular cartilage lesions were present in 109 (70.3%) hips. The location of the lesions was superior-anterior. Independent risk factors for the presence of acetabular rim articular cartilage lesions were an alpha-angle equal or greater than 55°, duration of symptoms equal or greater than 20 months, and Tegner activity scale level equal or greater than 6. Discussion. Although patients were classified as Tönnis grade 0 and 1, and 3tesla MRI reported acetabular lesions in 1.3% of cases, there was a high frequency of acetabular rim cartilage lesions. Knowledge of the independent risk factors associated with acetabular rim articular cartilage lesions may assist the orthopaedic surgeon with the decision to perform hip arthroscopy (AU)

Resultados radiológicos de la osteotomía en chevron modificada por Johnson para la corrección del hallux valgus / Radiological results of Johnson's modified chevron osteotomy to address hallux valgus

Objetivo. El propósito del presente estudio fue valorar los resultados radiológicos tras la osteotomía en chevron del primer metatarsiano para el tratamiento del hallux valgus. Material y método. La muestra consta de 24 pacientes consecutivos (27 pies) de los que 21 fueron mujeres y 3 varones, con una edad media de 44,4 años. En todos los casos se realizaron radiografías en carga donde se midieron preoperatoriamente y al final del seguimiento los siguientes ángulos: metatarsofalángico (MTF), intermetatarsiano (M1-M2), de apertura del antepié (M1-M5) y articular metatarsal distal (DMAA). Asimismo, se midieron las longitudes relativas del primer metatarsiano y la posición de los sesamoideos todo ello mediante métodos estandarizados. Resultados. No hubo complicaciones de interés. El seguimiento medio fue de 23 meses (6 a 50). Con la intervención se mejoraron todos los ángulos de manera significativa (p = 0,01). El acortamiento del primer metatarsiano fue de 0,018 (1,8%). En cuanto al desplazamiento de los sesamoideos se consiguió una mejoría en la posición postoperatoria de los mismos con un 96,2% de resultados G-0 y G-1 (desplazamiento 0%-50%). Conclusiones. La osteotomía en chevron se ha mostrado eficaz para corregir las deformidades angulares asociadas al hallux valgus leve-moderado, incluido el DMAA, con un acortamiento mínimo del primer metatarsiano

Purpose. The purpose of this study was to asses the radiological results obtained further to chevron osteotomy of the first metatarsal for the treatment of hallux valgus. Materials and methods. The sample consists of 24 consecutive patients (27 feet) of whom 21 were female and 3 male, with a mean age of 44.4 years. In all cases weight-bearing radiographs were made on which the following angles were measured both preoperatively and at the end of follow-up: metatarsal-phalangeal (MTP), intermetatarsal (M1-M2), the M1-M5 angle and the distal metatarsal articular angle (DMAA). Likewise, the relative length of the first metatarsal and the position of the sesamoid bones were measured by means of standardized methods. Results. There were not any significant complications. Average follow-up was 3 months (range: 6-50). The procedure managed to improve all angles considerably (p= 0.01). Shortening of the first metatarsal was 0.018 (1.8%). As regards sesamoid displacement, a substantial improvement was obtained vis-à-vis the preoperative situation, with 96.2% of results in the G-0 and G-1 range (displacement 0%-50%). Conclusions. Chevron osteotomy has shown to be an effective method to correct hallux valgus-associated angle deformities in the mid-moderate range, including DMAA angle, which a minimal shortening of the first metatarsal
