ABSTRACT

Resumen: Introducción: La luxación tibiofibular proximal (LTFP) es una lesión poco frecuente y no diagnosticada. De no ser tratada a tiempo, puede generar una sintomatología crónica de dolor e inestabilidad. La escasa evidencia disponible no entrega un protocolo de enfrentamiento ni consenso respecto a su manejo. Con el objetivo de asistir al enfrentamiento de esta lesión, se presenta una revisión de la literatura de una LTFP con reducción espontánea. Caso clínico: Hombre de 22 años consulta por dolor intenso en su rodilla derecha, posterior a caída en cuatrimoto. Al examen físico con aumento de volumen doloroso en cara lateral de la rodilla y pierna proximal, con movilidad completa y estable. Radiografías son informadas sin alteraciones. Se mantiene la sospecha clínica de LTFP, se continúa estudio con resonancia magnética (RM), la que es sugerente de LTFP. Dentro de las 24 horas de evolución, el paciente indica haber sentido un clank espontáneo en su rodilla afectada con cese completo de sintomatología. Se sigue al paciente por tres meses con RM de control, manteniendo una rodilla asintomática; examen físico y funcionalidad normal. Conclusión: El diagnóstico de las LTFP requiere un adecuado uso de imágenes. Su manejo consiste en una reducción cerrada de urgencia y de no lograrse, una reducción abierta, reparación y fijación interna. El pronóstico de las reducciones espontáneas es incierto, por lo que deben ser seguidas de forma seriada y en caso de recidiva, manejadas quirúrgicamente según el tiempo de evolución.


Abstract: Introduction: Proximal tibiofibular joint dislocations (PTFJD) are uncommon and underdiagnosed injuries. Urgent reduction is mandatory to avoid chronic disfunction. The scarcely available literature does not present a unified management guideline. An acute PTFJD case report with spontaneous reduction and a review of the literature is presented, aiming to assist the diagnosis and management of this pathology. Case report: A 22-years old male presented to the emergency department with high intensity right knee pain after falling in a four-wheel motorcycle. The physical exam revealed a prominent painful mass on the lateral aspect of his knee and proximal leg. His range of motion and knee stability were unremarkable. X-rays were informed negative for musculoskeletal injuries. According to a sustained suspicion of PTFJD, the study was continued with a magnetic resonance imaging (MRI), which suggested PTFJD. During the following 24 hours, the patient referred he was entirely asymptomatic after feeling a loud «clank¼. He has been followed for three months with MRI, and remains asymptomatic with full functions. Conclusion: PTFJD diagnosis requires appropriate images. Urgent close reduction is mandatory; if unsuccessful, open reduction, primary repair and internal fixation are indicated. The prognosis of spontaneous reduction remains uncertain and requires a serial clinical evaluation. In the case of recurrence, the appropriate surgical management is indicated according to the elapsed time from the injury.

ABSTRACT

Las lesiones meniscales en niños son cada día más frecuentes. La preservación meniscal es una prioridad en este grupo de pacientes, sin embargo, existen pocos artículos que muestran los resultados de suturas meniscales en niños. OBJETIVO: El objetivo de este estudio es identificar factores de riesgo de falla en pacientes sometidos a una sutura meniscal en niños menores de 18 años. MÉTODO: Estudio retrospectivo de 35 pacientes sometidos a una sutura meniscal, con una edad promedio de 16 años (13­18) y un seguimiento de 71 meses de media (16­115). Se evaluaron 6 variables: tipo, localización y tamaño de la lesión, edad, técnica quirúrgica y asociación a rotura de ligamento cruzado anterior (LCA). Los pacientes que presentaron falla de la sutura meniscal fueron identificados y sometidos a una regresión logística usando un modelo Stata V.14.0. RESULTADOS: 9 pacientes (24.3%) presentaron una falla en su cirugía durante el seguimiento. Lesiones iniciales mayores a 16 mm mostraron una tasa de re-rotura de un 73% independiente de la técnica quirúrgica. En lesiones menores a 16 mm, se obtuvo un 78% de reparaciones exitosas. No se encontró relación entre la re-rotura meniscal y lesión de LCA, tipo y localización de la lesión, técnica quirúrgica y edad de los pacientes. CONCLUSIÓN: Este estudio muestra que la reparación meniscal en niños tiene buenos resultados con una tasa de éxito promedio de un 75%. El riesgo de falla de sutura meniscal se correlacionó con el tamaño inicial de la lesión con un 73% de fallo en lesiones mayores a 16 mm independientemente del tipo de cirugía.


Meniscal tears are uncommon in the pediatric population, with an increasing number. Currently meniscal preservation is a priority when treating these injuries. However, only a few studies have reported the clinical outcomes of arthroscopic meniscal repair in children and its risk factors of failure. OBJECTIVE: Identify risk factors related to meniscal suture failure in patients under 18 years who underwent a meniscal repair. METHODS: Retrospective study of 35 patients with an average age of 16 years (13 - 18) who underwent arthroscopic meniscal repair with a mean follow up of 71.1 months (16­115). We evaluate 6 variables: type, location and size of meniscal tear, age, surgical technique and anterior cruciate ligament (ACL) association. Patients with re-rupture were identified and statistical analysis was performed through a logistic regression model using Stata V.14.0. RESULTS: 9 patients (24.3%) presented a suture failure during follow-up. Average time for re-rupture was 16 months (4­60 months). With an initial tear size of 16 mm or bigger, 73% of the meniscal repair will fail despite surgery technique. With an initial tear size smaller than 16 mm, 78% of will heal. No association was found between meniscal re-rupture and ACL rupture, type and location of tear, surgical technique and age. Conclusion: In our study meniscal repairs in pediatric population had good overall results with a global healing rate of 75.7%. The risk of suture failure was related to the initial size of meniscal tear: when meniscal tear is bigger than 16 mm, 73% of them will fail despite surgery.

ABSTRACT

Objetivo. Evaluar los resultados clínicos en pacientes con inestabilidad femoropatelar sometidos a reconstrucción del ligamento patelofemoral medial (LPFM) con auto y aloinjerto. Pacientes y metodología. Evaluación clínica retrospectiva de 28 pacientes con inestabilidad femoropatelar sometidos a cirugía de reconstrucción LPFM; se analizaron un grupo de 13 pacientes (13 rodillas) en que se utilizó autoinjerto obtenido de los tendones isquiotibiales y otro grupo de 15 pacientes (16 rodillas) con aloinjerto. El grupo total correspondió a 13 hombres y 15 mujeres con edades entre 15-38 años. Se estudió la morbilidad asociada al injerto y técnica quirúrgica, se realizó evaluación clínica con escala de Kujala, pre y postoperatoria y se evaluaron sus complicaciones. El seguimiento fue mayor a 12 meses. Resultados. No encontramos episodios de reluxación ni complicaciones asociadas al injerto en ninguno de los grupos. El puntaje promedio postoperatorio de la escala de Kujala en el grupo de autoinjerto fue de 89,2 y en el grupo de aloinjerto fue de 92,6 (p > 0,05). En el grupo de autoinjertos un paciente fue reoperado por mala posición del material de osteosíntesis y en el grupo de aloinjertos un paciente presentó una fractura de rótula no desplazada provocada por los túneles óseos realizados y otro paciente requirió movilización bajo anestesia por déficit de flexión. Conclusión. No encontramos diferencias significativas entre ambos grupos y los resultados clínicos fueron similares (AU)


Objective. The purpose of the study was to evaluate the functional results after medial patellofemoral ligament (MPFL) reconstruction in patients using auto- and allograft. Patients and Methods. A retrospective study was conducted on 28 patients with recurrent patellar dislocation, with 13 patients (13 knees) undergoing MPFL reconstruction with hamstring autograft, and 15 patients (16 knees) with reconstruction surgery with allograft. The total group included 13 males and 15 females, with an age range of 15 to 38 years. The graft-related morbidity was studied and a clinical assessment was performed using the pre- and postoperative Kujala score. Associated complications were reported for each group. All the patients had more than 12 months of follow up. Results. No recurrent dislocations or graft related complications were reported in either group. The post-operative Kujala subjective knee score was 89.2 in the autograft group, and 92.6 in the allograft group (p > .05). One patient in the allograft group received a revision surgery due to poor positioning of anchors. Another patient in the allograft group had non-displaced patella fracture related to the bone tunnels and another patient had flexion deficit and needed mobilization under anesthesia. Conclusion. There were no significant differences between both groups, and the results were comparable (AU)

PATIENTS AND METHODS: A retrospective study was conducted on 28 patients with recurrent patellar dislocation, with 13 patients (13 knees) undergoing MPFL reconstruction with hamstring autograft, and 15 patients (16 knees) with reconstruction surgery with allograft. The total group included 13 males and 15 females, with an age range of 15 to 38 years. The graft-related morbidity was studied and a clinical assessment was performed using the pre- and postoperative Kujala score. Associated complications were reported for each group. All the patients had more than 12 months of follow up. RESULTS: No recurrent dislocations or graft related complications were reported in either group. The post-operative Kujala subjective knee score was 89.2 in the autograft group, and 92.6 in the allograft group (p >.05). One patient in the allograft group received a revision surgery due to poor positioning of anchors. Another patient in the allograft group had non-displaced patella fracture related to the bone tunnels and another patient had flexion deficit and needed mobilization under anesthesia. CONCLUSION: There were no significant differences between both groups, and the results were comparable.
