ABSTRACT
Objectives The aim of this is to investigate the changes in body mass index (BMI) following knee arthroplasty and to evaluate their impact on patient-reported outcomes and functional evaluations. Methods This observational study included 90 patients who underwent total knee arthroplasty (TKA) and were followed up for a median period of 2.6 years. BMI measurements were recorded before and after surgery, and patient-reported outcomes and functional evaluations were assessed using standardized scales and tests. Results Following TKA, BMI increased statistically significantly (Wilcoxon signed-rank test, p < 0.000). In addition, half of the patients experienced an increase in BMI, with 32% moving up in their BMI category. However, there were no clinically significant differences in patient-reported outcomes or functional evaluations between the group that gained BMI and the group that maintained or lost BMI. Conclusion This study reveals that patients tend to have increased BMI following TKA. However, these BMI changes do not significantly impact patient-reported outcomes or functional evaluations. It underscores the importance of patient education regarding healthy lifestyle habits, including diet and physical activity, to address postoperative weight gain effectively.
ABSTRACT
PURPOSE: The purpose of this study was to assess patient satisfaction and identify risk factors for dissatisfaction after anterior stabilised conventional total knee arthroplasty (TKA) without patellar resurfacing, using the Goodman score. METHODS: We conducted a cross-sectional study using data from our institutional database from 1 January 2018 to 1 March 2021. Patients who underwent TKA with the Vanguard® Cruciate Retaining Anterior Stabilized Knee System (Zimmer Biomet, Warsaw, Indiana, USA) without patellar replacement were included. Patients with other bearing surfaces (posterior stabilised or medial congruent) or diagnosed with infection or instability were excluded. Patients' reported outcomes, body mass index (BMI), passive range of motion, the timed up-and-go test, sit-up test, and algometry were assessed. Patients were also asked if they had anterior knee pain. Satisfaction was assessed using the Goodman scale, and logistic multivariate regression was used to identify variables associated with dissatisfaction and perceived improvement in quality of life. RESULTS: A total of 131 TKA patients were included in the study. The median satisfaction score was 100 (interquartile range [IQR], 87.5 to 100), with the 75-point threshold at the 90th percentile according to Section A of Goodman. Section B of Goodman showed that 113 TKA patients (86.26%) reported "great improvement" or "more than I ever dreamed." Multivariate logistic regression revealed that anterior knee pain (OR 5.16, 95% CI 1.24 to 21.39), the sit-up test (OR 0.63, 95% CI 0.49 to 0.81), and BMI (OR 0.84, 95% CI 0.70 to 0.99) were significantly associated with patient dissatisfaction and a worse perceived improvement in quality of life. The receiver operating characteristics curve for the models had areas under the curve of 0.83 (95% CI 0.69 to 0.97) and 0.82 (95% CI 0.70 to 0.94), respectively. CONCLUSION: Anterior stabilised TKA without patellar resurfacing can achieve 90% satisfaction and 86% improvement in quality of life. To improve these results, it is essential to prevent and treat anterior knee pain and enhance quadriceps strength. LEVEL OF EVIDENCE: Level III (retrospective cohort study).
ABSTRACT
INTRODUCCIÓN: la lesión de los vasos subclavios durante la cirugía de clavícula es una situación rara, de suceder podría resultar incluso mortal; conocer su ubicación es indispensable para minimizar ese riesgo.OBJETIVO: determinar la ubicación y la distancia de la AS y VS respecto a la clavícula. Secundariamente, identificar las características particulares que influencien la ubicación y la distancia. MATERIALES Y MÉTODO: estudio retrospectivo, AngioTAC de tórax y cuello entre 2012 y 2017; se midió la longitud de la clavícula, distancia y dirección de los vasos subclavios en cada tercio de la clavícula, como también la angulación entre una horizontal y el centro de los vasos subclavios. Resultados: 39 AngioTC, 78 hombros. Distancia AS/clavícula tercio proximal, medio y distal 32,8mm (20,3-46,3), 15,4mm (6,8-28,0) y 62,7mm (37,0-115,4) respectivamente. La distancia VS/clavícula tercio proximal, medio y distal fue: 7,4mm (1,0-19,2), 16,2mm (6,7-34,7) y 67,1mm (29,7-117,0) respectivamente. La ubicación de AS y VS con respecto a la clavícula es posterosuperior en el tercio proximal, posteroinferior en el tercio medio e inferior en el tercio distal. CONCLUSIÓN: En el tercio proximal la vena puede estar solo a 1mm de la clavícula y la arteria a 6mm en dirección antero-posterior, resultando esa zona la más peligrosa. En el tercio medio la distancia es mayor, pudiendo estar arteria y vena a solo 6mm, la dirección de brocado más peligrosa es antero-inferior con una inclinación promedio de 45° caudal. El tercio distal es el más seguro, los vasos están al menos a 30mm de distancia hacia caudal. Nivel de evidencia III.
BACKGROUND: injury to the subclavian vessels during clavicle surgery is a rare situation, if it happens it could even be fatal; knowing their location is essential to minimize that risk. OBJECTIVE: determine location and distance of the AS and VS with respect to the clavicle. Secondarily identify particular characteristics that influence location and distance. MATERIAL AND METHODS: retrospective study, AngioTAC of thorax and neck between 2012 and 2017; it was measured the length of the clavicle, distance and direction of the subclavian vessels in each third of the clavicle and angulation between a horizontal and the center of the subclavian vessels were measured. Results: 39 AngioTC, 78 shoulders. AS / clavicle third proximal, middle and distal distance 32.8mm (20.3-46.3), 15.4mm (6.8-28.0) and 62.7mm (37.0-115.4) respectively. Distance VS / clavicle third proximal, middle and distal was: 7.4mm (1.0-19.2), 16.2mm (6.7-34.7) and 67.1mm (29.7-117.0) respectively. The location of AS and VS with respect to the clavicle is posterosuperior in the proximal third, posteroinferior in the middle third and inferior in the distal third. CONCLUSION: In the proximal third the vein can be only 1mm from the clavicle and the artery to 6mm in the anterior-posterior direction, this zone is the most dangerous. In the middle third the distance is greater, artery and vein can be only to 6mm, the most dangerous drilling direction is antero-inferior with an average inclination of 45° caudal. The distal third is the safest, the vessels are at least 30mm away from the vessels. Level of evidence III.

INTRODUCTION: Among the possibilities for the management of osteoarthritis, different pharmacological alternatives have been proposed, being diacerein one of them due to its anti-inflammatory effect. However, diacerein clinical utility is not clear. METHODS: To answer this question, we used Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We extracted data from the systematic reviews, reanalyzed data of primary studies, conducted a meta-analysis and generated a summary of findings table using the GRADE approach. RESULTS AND CONCLUSION: We concluded diacerein may lead to a slight reduction in pain and probably not improve functionality among patients with knee osteoarthritis and can frequently present diarrhea as an adverse effect.

INTRODUCCIÓN: Dentro de las opciones para el manejo de la artrosis se han planteado distintas alternativas farmacológicas, entre ellas la diacereína, por su efecto antiinflamatorio. Sin embargo, su real utilidad clínica no está clara. MÉTODOS: Para responder esta pregunta utilizamos Epistemonikos, la mayor base de datos de revisiones sistemáticas en salud a nivel mundial, la cual es mantenida mediante búsquedas en múltiples fuentes de información, incluyendo MEDLINE, EMBASE, Cochrane, entre otras. Extrajimos los datos desde las revisiones identificadas, reanalizamos los datos de los estudios primarios, realizamos un metanálisis, preparamos tablas de resumen de los resultados utilizando el método GRADE. RESULTADOS Y CONCLUSIONES: Identificamos cinco revisiones sistemáticas que en conjunto incluyen nueve estudios primarios, de los cuales, todos son ensayos aleatorizados. Concluimos que la diacereína probablemente produce una leve disminución del dolor en pacientes con artrosis, pero no mejoraría la funcionalidad y tiene como efecto adverso frecuente la aparición de diarrea.
