Hip arthroscopy for femoroacetabular impingement with 10-year minimum follow-up. / Artroscopia de cadera como tratamiento del choque femoroacetabular con seguimiento mínimo de 10 años.

PURPOSE: To determine outcomes after hip arthroscopy (HA) for femoroacetabular impingement (FAI) at a minimun 10-year follow up and identified risk factors for revision surgery. METHODS: Retrospective study of a prospective database of patients undergoing HA between January 2010 and December 2011. Rim chondral injuries were evaluated using the acetabular labral articular disruptions system (ALAD). Clinical and radiological data was obtained. Cumulative survival was estimated by Kaplan-Meier and a multivariate Cox proportional hazards model. RESULTS: Seventy-four patients were included in the study. Mean follow-up was 132 months. There was statistically significant improvement from preoperative PROs at latest follow-up. Seventeen patients (23.9%) underwent revision surgery. Odds ratio for revision surgery was 8.08 in a patient above 40 years old, 7.57 in a patient Tönnis greater than 1, and 4.25 in a patient ALAD 2-3. Cumulative survivorship rate at 10 years was 77.8%, with a 45.4% for patients with Tönnis grade greater than 1 in front of 85.2% for patients with Tönnis grade of 1 or less (P<.001). Risk factor for revision surgery was preoperative degree of osteoarthrosis (P=.02). CONCLUSION: Cumulative survivorship rate at 10 years was 45.4% for patients with Tönnis grade greater than 1 in front of 85.2% for patients with Tönnis grade of 1 or less (P<.001). Age, chondral injuries, and degree of osteoarthrosis would increase the risk for revision surgery.

Past and projected temporal trends in arthroscopic hip surgery in Spain between 1998 and 2018. / Tendencias temporales pasadas y proyectadas en la cirugía artroscópica de cadera en España entre 1998 y 2018.

OBJECTIVE: Describe the population incidence of hip arthroscopy from 1998 to 2018 and to project the trends for the year 2030, as well as to describe the variations in the population incidence between the autonomous communities. MATERIAL AND METHOD: A retrospective review of the minimum basic data set from 1998 to 2018 was carried out. Temporal evolution was analyzed and the variables associated with the indication (age, sex, regions) were identified. For each region, the crude rate per 100,000 inhabitants was calculated. The 2019-2030 projection was made using linear regression. RESULTS: In Spain between 1998 and 2018 a total of 10,663 arthroscopic hip surgeries were carried out. The population incidence in 1998 was 0.14 CAC per 100,000 inhabitants, while in 2018 it was 4.09. For the year 2030 an increase of 156.9% in the number of arthroscopic hip surgeries is expected (P<.001). On average, 57.7% of all procedures (95% CI 55.2-60.2) were done in men and the highest incidence was found in ages ≤44 years. The geographical variation was 81%, being up to 15.4 times the difference in incidence per 100,000 inhabitants between some regions. CONCLUSIONS: The number of hip arthroscopies in Spain has been increasing in the 1998-2018 period and this growing trend is expected to continue until 2030. In Spain, hip arthroscopic procedures are performed more frequently in male patients and in under 45 years old. The variability of the population incidence between the autonomous communities is high.

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.

[Scientific and research activity and degree of satisfaction of residents of Orthopedic Surgery and Traumatology in different hospitals of the health network in Spain]. / Actividad científica e investigadora y grado de satisfacción de residentes de Cirugía Ortopédica y Traumatología en diferentes hospitales de la red sanitaria en España.

INTRODUCTION: Healthcare pressure has changed the acquisition of knowledge during residency training. The aim of this study was to analyze the clinical and research training, and level of satisfaction, during orthopedic and traumatology residency in different hospitals of the Spanish National Health Service. MATERIAL AND METHODS: An online survey was distributed between 06/25/2020 and 07/31/2020. Demographic, institution, clinical and research variables were analyzed. Satisfaction was graded in a scale from 0 to 5. RESULTS: 120 residents answered the survey, having a mean age of 27 years and being 58% male. Distribution of residents by year was 26 R5 (21.7%), 24 R4 (20.0%), 45 R3 (37.5%), 25 R2 (20.9%). Only 37.5% answered that they did not have any clinical activity the next day after medical guard, and 45% answered that they performed clinical activity outside of working hours. A total of 56.7% answered that their orthopedic training program did not include research training. No resident had specific time assigned to research activities. Mean satisfaction value was 2.4 points. CONCLUSIONS: Clinical activity shows aspects incompatible with current legislation. Orthopedic programs need improvements with regard to research training. A significant percentage of residents are unsatisfied with their training.

INTRODUCCIÓN: La presión asistencial ha provocado un desequilibrio hacia la vertiente clínica con respecto a la científica. El propósito del trabajo fue analizar la actividad asistencial e investigadora y el grado de satisfacción en los residentes de cirugía ortopédica y traumatología, en diferentes hospitales de la red sanitaria en España. MATERIAL Y MÉTODOS: Encuesta de ámbito estatal realizada en el período del 25/06/2020 al 31/07/2020. Se analizaron variables demográficas y del servicio, de labores asistencial e investigadora. Se determinó la satisfacción del residente en escala continua de cero a 5. RESULTADOS: 120 médicos haciendo residencia respondieron a la encuesta, rondando una edad media de 27 años y predominio de varones en 58%. La distribución por año de dichos residentes fue de 26 R5 (21.7%), 24 R4 (20.0%), 45 R3 (37.5%), 25 R2 (20.9%). Sólo 37.5% indicaron carecer de labor de tipo asistencial asignada el día siguiente de la guardia y 45% respondieron que realizaban algún papel asistencial fuera del horario laboral del hospital. De esos interrogados, 56.7% contestaron que su plan individual de formación no contemplaba la praxis científica ajustada a su año de residencia como un objetivo a cumplir. Ninguno de ellos tenía tiempo asignado con periodicidad semanal para acciones de investigación. El valor medio del nivel de satisfacción de estos médicos fue de 2.4 puntos. CONCLUSIONES: La actividad asistencial presenta aspectos incompatibles con la legislación actual. Los planes individuales de adiestramiento precisan mejoras con respecto a la ocupación investigadora. Un porcentaje no despreciable de estos estudiantes de posgrado no estaban satisfechos con su plan personal de especialización.

Comparative cohort study of the SuperPath approach and the conventional posterior approach in primary cementless hip replacement surgery. / 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.

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.

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

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.

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

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.
