RESUMEN
INTRODUCTION@#The use of periarticular (PA) tranexamic acid (TXA) and its efficacy in comparison with intra-articular (IA) TXA have not been well explored in the literature. This retrospective cohort study aimed to compare the effects of IA and PA TXA with analgesic components in reducing blood loss and improving immediate postoperative pain relief and functional outcomes in patients after unilateral primary total knee arthroplasty (TKA).@*METHODS@#A total of 63 patients underwent TKA, and they were divided into the IA TXA delivery group ( n = 42) and PA TXA delivery group ( n = 21). All patients were administered 1 g of TXA. They also received pericapsular infiltration consisting of 0.5 mL of adrenaline, 0.4 mL of morphine, 1 g of vancomycin, 1 mL of ketorolac and 15 mL of ropivacaine. Outcomes for blood loss and surrogate markers for immediate functional recovery were measured.@*RESULTS@#Of the 63 patients, 54% were female and 46% male. The mean drop in postoperative haemoglobin levels in the PA and IA groups was 2.0 g/dL and 1.6 g/dL, respectively, and this was not statistically significant ( P = 0.10). The mean haematocrit drop in the PA and IA groups was 6.1% and 5.3%, respectively, and this was also not statistically significant ( P = 0.58). The postoperative day (POD) 1 and discharge day flexion angles, POD 1 and POD 2 visual analogue scale (VAS) scores, gait distance on discharge and length of hospitalisation stay were largely similar in the two groups.@*CONCLUSION@#Our study showed that both IA and PA TXA with analgesic components were equally efficient in reducing blood loss and improving immediate postoperative pain relief and functional outcomes.

Abstract Objective We studied the microbiological profile of periprosthetic knee infections treated in a Brazilian tertiary hospital. Methods The study included all patients undergoing revision surgery for total knee arthroplasty (RTKA) between November 2019 and December 2021, with a diagnosis of periprosthetic infection confirmed per the 2018 International Consensus Meeting (ICM) criteria. Results Sixty-two patients had a periprosthetic joint infection (PJI) per the 2018 ICM criteria. Cultures were monomicrobial in 79% and polymicrobial in 21% of cases. The most frequent bacterium in microbiological tissue and synovial fluid cultures was Staphylococcus aureus, observed in 26% of PJI patients. Periprosthetic joint infection with negative cultures occurred in 23% of patients. Conclusion Our results show the following: i) a high prevalence of Staphylococcus as an etiological agent for knee PJI; ii) a high incidence of polymicrobial infections in early infections; iii) the occurrence of PJI with negative cultures in approximately one fourth of the subjects.

Abstract Objective The present study aims to evaluate the effectiveness of the periarticular hip infiltration technique in the postoperative period of total hip arthroplasty. Methods This is a randomized double-blind controlled clinical trial in patients with femoral neck fractures or hip osteoarthritis submitted to a total hip arthroplasty at our institution. The periarticular infiltration technique consisted of the administration of an anesthetic (levobupivacaine) and a steroid (dexamethasone) agent in the nociceptor-rich tissues of the hip after orthopedic implants placement. The control group received an injection of 0.9% saline into the same tissues. Pain, range of motion, and use of opioid analgesic agents after 24 and 48hours of the procedure were evaluated, as well as the presence of adverse effects, time to resume walking, and total hospitalization time. Results The study evaluated 34 patients. The experimental group required fewer opioid agents between 24 and 48 hours. The reduction in pain scores was greater in the placebo group. Conclusion Periarticular anesthetic infiltration as a method of postoperative analgesia for total hip arthroplasty reduced the rates of opioid intake between 24 and 48hours. It provided no benefits regarding pain, mobility, length of stay, or complications.
Resumo Objetivo Este estudo tem como objetivo avaliar a eficácia da técnica de infiltração periarticular do quadril no pós-operatório de artroplastia total do quadril.

Abstract Objective Due to the popularity of 3D technology, surgeons can create specific surgical guides and sterilize them in their institutions. The aim of the present study is to compare the efficacy of the autoclave and ethylene oxide (EO) sterilization methods for objects produced by 3D printing with polylactic acid (PLA) material. Methods Forty cubic-shaped objects were printed with PLA material. Twenty were solid and 20 were hollow (printed with little internal filling). Twenty objects (10 solid and 10 hollow) were sterilized in autoclave, forming Group 1. The others (10 solid and 10 hollow) were sterilized in EO, composing Group 2. After sterilization, they were stored and referred to culture. Hollow objects of both groups were broken during sowing, communicating the dead space with the culture medium. The results obtained were statistically analyzed (Fisher exact test and residue analysis). Results In group 1 (autoclave), there was bacterial growth in 50% of solid objects and in 30% of hollow objects. In group 2 (EO), growth occurred in 20% of hollow objects, with no bacterial growth in solid objects (100% of negative samples). The bacteria isolated in the positive cases was non-coagulase-producing Staphylococcus Gram positive. Conclusions Sterilization by both autoclave and EO was not effective for hollow printed objects. Solid objects sterilized by autoclave did not demonstrate 100% of negative samples and were not safe in the present assay. Complete absence of contamination occurred only with solid objects sterilized by EO, which is the combination recommended by the authors.
Resumo Objetivo Devido à popularidade da tecnologia 3D, cirurgiões podem criar guias cirúrgicos específicos e esterilizá-los nas suas instituições. O objetivo do presente estudo é comparar a eficácia dos métodos de esterilização por autoclave e óxido de etileno (OE) de objetos produzidos pela impressão 3D com material ácido polilático (PLA, na sigla em inglês). Métodos Quarenta objetos em formato cúbico foram impressos com material de PLA. Vinte eram sólidos e 20 eram ocos (impressos com pouco enchimento interno). Vinte objetos (10 sólidos e 10 ocos) foram esterilizados em autoclave, formando o Grupo 1. Os demais (10 sólidos e 10 ocos) foram esterilizados em OE, compondo o Grupo 2. Após a esterilização, os objetos foram armazenados e encaminhados para cultura. Objetos ocos de ambos os grupos foram quebrados durante a semeadura, comunicando o espaço morto com o meio de cultura. Os resultados obtidos foram analisados estatisticamente (teste exato de Fisher e análise de resíduo). Resultados No grupo 1 (autoclave) houve crescimento bacteriano em 50% dos objetos sólidos e em 30% dos objetos ocos. No grupo 2 (OE) o crescimento ocorreu em 20% dos objetos ocos, com ausência de crescimento bacteriano nos objetos sólidos (100% de amostras negativas). A bactéria isolada nos casos positivos foi Staphylococcus Gram positivo não produtor de coagulase. Conclusões A esterilização tanto em autoclave quanto pelo OE não foi eficaz para objetos impressos no formato oco. Objetos sólidos esterilizados em autoclave não demonstraram 100% de amostras negativas, não sendo seguro no presente ensaio. Ausência completa de contaminação ocorreu apenas com objetos sólidos esterilizados pelo OE, sendo a combinação recomendada pelos autores.

Introducción: La capsulitis adhesiva es una enfermedad que se caracteriza por el engrosamiento de la cápsula articular del hombro, lo que se traduce clínicamente en dolor y una pérdida progresiva de la movilidad. El tratamiento conservador es la primera opción. En este estudio, se evaluó el uso de corticoesteroides articulares para el manejo de este cuadro. Materiales y Métodos: Se llevó a cabo un estudio retrospectivo entre 2015 y 2020. Se evaluaron los registros de consulta externa de pacientes con diagnóstico de capsulitis adhesiva u hombro congelado, que recibieron tratamiento con corticoesteroides por vía oral o articular. Resultados: Se analizó a 19 pacientes, 8 recibieron tratamiento por vía oral y 11, por vía articular. Hubo una mejoría importante en ambos grupos, pero los pacientes que recibieron corticoesteroides articulares comunicaron una mejoría a largo plazo. Conclusiones: La administración de corticoesteroides tanto por vía oral como articular para tratar la capsulitis adhesiva fue eficaz; sin embargo, a largo plazo, los corticoesteroides articulares resultaron más eficaces. Nivel de Evidencia: III
Introduction: Adhesive capsulitis is a condition defined by thickening of the shoulder joint capsule, which clinically translates into discomfort and progressive loss of range of motion, with conservative therapy being the initial option. In this study, we evaluate the use of intra-articular corticosteroid injections for the treatment of this condition. Materials and Methods: A retrospective analysis was conducted between 2015 and 2020, assessing the outpatient records of patients diagnosed with adhesive capsulitis or frozen shoulder and treated with corticosteroids either orally or intra-articularly. Results: A total of 19 patients were analyzed, 8 received oral treatment and 11 received intra-articular injection, with both groups showing considerable improvement, with the difference that the patients in the articular corticosteroid group reported long-term improvement. Conclusion: Corticosteroids have been found to be effective in the treatment of adhesive capsulitis both orally and by intra-articular injection; however, intra-articular corticosteroids have proved to be more effective in the long term. Level of Evidence: III

OBJECTIVE@#To explore clinical effect of arthroscopic debridement combined with platelet-rich plasma (PRP) injection for Kellgren-Lawrence(K-L) gradeⅠ-Ⅲ knee osteoarthritis (KOA) .@*METHODS@#Totally 117 patients with KOA who underwent arthroscopic debridement combined with injection from November 2015 to January 2019 were retrospectively analyzed. According to different injection drugs, the patients were divided into sodium hyaluronate group(group A) and PRP group(group B). In group A, there were 60 patients, including 27 males and 33 females, aged from 49 to 67 years old with an average age of (54.1±4.8) years old;12 patients with gradeⅠ, 23 patients with gradeⅡand 25 patients with grade Ⅲ according to K-L clssification, 2 ml(20 g) sodium hyaluronate was injected into knee joint after intraoperative, 1, 2, 3 weeks after operation for 4 times. In group B, there were 57 patients, including 25 males and 32 females, aged from 47 to 70 years old with an average of (55.8±5.0) years old, 10 patients with gradeⅠ, 20 patients with gradeⅡand 27 patients with grade Ⅲ according to K-L classification, injected 5 ml PRP at the same time. Postoperative complications was recorded between two groups. Postoperative visual analogue scale(VAS) and Lysholm score at 3, 6, 12 months were used to evaluate improvement of knee pain and joint function.@*RESULTS@#All patients were followed up for 12 to 19 months with an average of (14.1±1.6) months. There was no significant difference in postopertaive complications between group A and group B (P>0.05). Postoperative VAS score in group A at 3, 6, 12 months were 3.0±0.8, 2.0±0.8, 2.6±0.9 respectively, and 2.9±0.8, 1.9±0.7, 2.2±0.8 in group B respectively; and no differnece at 3 and 6 months after operation between two groups (P<0.05), while VAS score in group B was higher than group A at 12 months after operation(P<0.05). Postoperative Lysholm score in group A at 1, 6, 12 months (86.6±1.8, 93.1±2.0, 86.7±1.7) were lower than group B(88.9±1.9, 95.0±2.0, 89.0±1.9)(P<0.05).@*CONCLUSION@#Arthroscopic debridement combined with sodium hyaluronate or PRP injection for K-L gradeⅠ-Ⅲ KOA could effectively relieve pain and improve joint function with higher safety in short term, but the medium-long-term effect of PRP injection is stable.

Objective: To evaluate the efficacy and safety of intra-articular injection of adalimumab (ADA) in the treatment of refractory oligoarticular juvenile idiopathic arthritis (JIA). Methods: This was a retrospective study. Clinical data on age, gender, and symptoms of joint swelling and pain were collected from 11 children with refractory oligoarticular JIA involving only knee joints admitted to Department of Rheumatism and Immunology of Children's Hospital, Capital Institute of Pediatrics from November 2019 to October 2020. The physician and parent-child evaluation of disease activity, the number of active joints, and the level of erythrocyte sedimentation rate (ESR) at different treatment time points were analyzed at every 4-week observation point after drug administration, and the non-parametric Kruskal-Wallis test was used to compare the differences in clinical evaluation indicators and changes in laboratory tests at different treatment times. The follow-up period was 6 months. Results: Among the 11 children, 5 were boys and 6 were girls. The age was 3.0 (2.8) years. All 11 children had symptoms of joint swelling and pain as well as limitation of movement. After 3 intra-articular injections of ADA, the joint symptoms of 11 children were better than before treatment; the joint symptoms of 7 children disappeared completely, and no recurrence occurred during the 6-month follow-up period. At different treatment times, physician and parent-child evaluation of disease activity, a gradual decrease in the number of active joints in the children, ESR, and juvenile arthritis disease activity score with 27 joints were all statistically significant (χ2=53.99, 59.37, 32.87, 40.07, 54.00, all P<0.001).No significant adverse drug reactions were observed in any of the 11 children during treatment and follow-up. Conclusion: Intra-articular injection of ADA in the treatment of refractory oligoarticular JIA has a significant effect in controlling joint symptoms and is relatively safe.

Introducción: Los desórdenes temporomandibulares son un grupo de trastornos que afectan la articulación temporomandibular y/o los tejidos musculoesqueléticos asociados. Objetivo: Determinar la efectividad de los concentrados de plaquetas en el tratamiento de los desórdenes temporomandibulares. Métodos: La búsqueda de la literatura fue realizada desde enero del 2014 hasta abril del 2019, en las bases de datos biomédicas: PubMed, Embase, SciELO, Scopus, Science Direct, Sistema de información sobre literatura gris en Europa, Literatura Latinoamericana y del Caribe en Ciencias de la Salud, Google Académico y el Registro Central de Ensayos Clínicos Cochrane. Se definieron como criterios de selección de los estudios que fueran ensayos clínicos aleatorizados, con una antigüedad máxima de cinco años, que reportarann la efectividad (reducción del dolor y aumento de apertura máxima) de los concentrados plaquetarios en el tratamiento de los desórdenes temporomandibulares. El riesgo de sesgo de los estudios fue analizado por medio del Manual Cochrane de revisiones sistemáticas de intervenciones. Resultados: La estrategia de búsqueda resultó en nueve artículos, de los cuales el 100 por ciento reportó que no había diferencia en la reducción del dolor y el aumento de apertura máxima de los concentrados plaquetarios en el tratamiento de los desórdenes temporomandibulares. Conclusiones: La literatura revisada sugiere que existe una ligera evidencia de los beneficios potenciales de las inyecciones intraarticulares de los concentrados plaquetarios en pacientes con desórdenes temporomandibulares. Sin embargo, es necesario establecer un protocolo estandarizado para la preparación y aplicación de estos concentrados(AU)
Introduction: Temporomandibular disorders are a group of dysfunctions which affect the temporomandibular joint and/or associated musculoskeletal tissues. Objective: Determine the effectiveness of platelet concentrates in the treatment of temporomandibular disorders. Methods: A bibliographic search was conducted from January 2014 to April 2019 in the biomedical databases PubMed, Embase, SciELO, Scopus, Science Direct, System for Information on Gray Literature in Europe, Latin American and Caribbean Health Sciences Literature, Google Scholar, and Cochrane Central Register of Clinical Trials. The following selection criteria were defined for the studies: randomized clinical trials published in the last five years and reporting on the effectiveness (pain reduction and maximum opening increase) of platelet concentrates in the treatment of temporomandibular disorders. Bias risk analysis was based on the Cochrane manual of systematic reviews of interventions. Results: Nine papers were retrieved, of which 100 percent reported no differences in pain reduction or maximum opening increase resulting from the use of platelet concentrates in the treatment of temporomandibular disorders. Conclusions: The literature review conducted suggests that there is slight evidence of the potential benefits of intra-articular injections of platelet concentrates in patients with temporomandibular disorders. However, a standardized protocol should be established for the preparation and application of these concentrates(AU)

Abstract Introduction: Tranexamic Acid (TXA), an antifibrinolytic that inhibits the fibrinolytic activity of plasmin is used to decrease perioperative blood loss and transfusion requirements in orthopedic surgery. The aim of our study was to compare postoperative bleeding in two intra-articular doses (1 g and 2 g) of tranexamic acid in adult patients undergoing unilateral total knee replacement. Method: We conducted a single-operator, randomized, and controlled, double-blind study in two groups. The G1 group received 1 g of intra-articular TXA and the G2 group 2 g of intra-articular TXA. Both groups received 15 mg kg-1 IV before the surgical incision (TXA induction dose) and then 10 mg kg-1, orally, 6 and 12 hours after the induction dose of TXA.The primary endpoint was bleeding measured by blood loss in postoperative drainage. Secondary outcomes were change in hemoglobin and hematocrit levels on the first and third postoperative days, and the need for transfusion during hospitalization. Results: In total, 100 patients were randomized, and 100 were included in the analysis. Blood loss in postoperative drainage was similar in both groups (200 ± 50 vs. 250 ± 50 mL, G1 and G2 groups respectively). Change in hematocrit and hemoglobin values (% of change) between preoperative and day 3 were not statically significant between groups G1 and G2 (18 ± 5 vs. 21 ± 4; 21 ± 7 vs. 22 ± 5 respectively). No patients received blood transfusion. Conclusions: Our study did not show superiority of 2 g of intra-articular tranexamic acid compared to 1 g.ClinicalTrials.gov Identifier NCT04085575
Resumo Introdução: O Ácido Tranexâmico (TXA), agente antifibrinolítico que inibe a atividade fibrinolítica da plasmina, é usado para reduzir a perda sanguínea perioperatória e a necessidade de transfusão em cirurgia ortopédica. O objetivo do estudo foi comparar o efeito de duas doses intra-articulares (1 g e 2 g) de ácido tranexâmico no sangramento pós-operatório de pacientes adultos submetidos a prótese total unilateral de joelho. Método: Realizamos estudo com operador único, randomizado, controlado e duplo-cego em dois grupos. O grupo G1 recebeu 1 g de TXA intra-articular e o grupo G2, 2 g de TXA intra-articular. Os dois grupos receberam 15 mg.kg-1 IV antes da incisão cirúrgica (dose de indução de TXA) e 10 mg.kg-1 por via oral, 6 e 12 horas após a dose de indução de TXA. O desfecho primário foi o sangramento medido pela perda sanguínea na drenagem pós-operatória. Os desfechos secundários foram alteração nos níveis de hemoglobina e hematócrito no primeiro e terceiro dias de pós-operatório e necessidade de transfusão durante a hospitalização. Resultados: Cem pacientes foram randomizados e 100 foram incluídos na análise. A perda sanguínea pela drenagem pós-operatória foi semelhante nos dois grupos (200 ± 50 mL vs. 250 ± 50 mL, grupos G1 e G2, respectivamente). A variação nos valores de hematócrito e hemoglobina (% de variação) entre o pré-operatório e o dia 3 não foi estatisticamente significante entre os grupos G1 e G2 (18 ± 5 vs. 21 ± 4; 21 ± 7 vs. 22 ± 5, respectivamente). Nenhum paciente recebeu transfusão de sangue. Conclusões: O estudo não mostrou superioridade na dose de 2 g de ácido tranexâmico intra-articular em comparação à dose de 1 g.

OBJECTIVES@#To evaluate the efficacy of different ways of cocktail analgesic mixture injection on total knee arthroplasty (TKA).@*METHODS@#A total of 50 patients with knee osteoarthritis treated by TKA from July to September 2018 were randomly divided into two groups (=25). The Group 1 underwent anterior intra-articular injection before prosthesis implanted while the Group 2 underwent posterior intra-articular injection before prosthesis implanted. Visual Analogue Scale (VAS) of all patients for pain during activity and at rest, maximal flexion degree of the knee at the 48th h and the 72th h after surgery, the time of raise leg, usage rate of patient-controlled analgesia (PCA), and complications were evaluated and analyzed.@*RESULTS@#VAS for pain at rest of patients in the Group 1 was significantly less than that in the Group 2 at the 6th, 12th, and 24th h after surgery (all <0.05). Maximal flexion degree of the knee at the 48th h and the 72th h after surgery in the Group 1 was better than that in the Group 2 (both <0.05). The Group 1 costed less time than the Group 2 on the ability to perform an active straight leg raise (=0.027).@*CONCLUSIONS@#The anterior intra-articular cocktail analgesic mixture injection can strongly relieve the pain early after TKA, which can improve knee function and achieve painless rehabilitation in most patients, with safety.

OBJECTIVE@#To investigate the effect of intra-articular injection of tranexamic acid on blood loss and blood transfusion rate after minimally invasive unicompartmental knee arthroplasty.@*METHODS@#From January 2015 to September 2017, 90 patients underwent minimally invasive unicompartmental knee arthroplasty were divided into tranexamic acid group and control group, 45 cases in each group. In the tranexamic acid group, there were 22 males and 23 females, aged 62 to 69 (66.1±2.4) years;in the control group, 20 males and 25 females, aged 63 to 71(68.5±5.2) years. The amount of bleeding in the drainage ball at 48 hours after operation was recorded, and the blood transfusion rate and hematocrit level duringthe perioperative period were recorded. The factors influencing perioperative blood loss included gender, age and body mass index (BMI).@*RESULTS@#All patients were followed up for 12.5 to 28.3 (22.8±7.9) months. During the follow-up, the wounds of the two groups healed well, and no deep vein thrombosis and pulmonary embolism occurred. There was no significant difference in postoperative blood loss between the tranexamic acid group and the control group. The postoperative bleeding volume in the tranexamic acid group was (110.0±52.1) ml, and that in the control group was (123.0±64.5) ml (P=0.39). There was no blood transfusion in the two groups.@*CONCLUSION@#Intra articular injection of tranexamic acid can not significantly reduce the postoperative blood loss in patients with minimally invasive unicompartment.

Resumen: Introducción: La artroscopía de rodilla es uno de los procedimientos que más comúnmente se realizan para tratar esta articulación. La anestesia general y el bloqueo espinal son las modalidades de anestesia más comunes para este procedimiento. Consideramos que esta cirugía se puede manejar con anestesia local intraarticular, con lo que se evitan estancias en recuperación más prolongadas; tiene un mejor manejo efectivo del dolor y optimización de tiempos prequirúrgicos, intraquirúrgicos y postquirúrgicos. Material y métodos: Estudio prospectivo, cuasiexperimental y longitudinal, realizado para comparar dos procedimientos anestésicos: la anestesia intraarticular (lidocaína con epinefrina, bupivacaína y fentanil) sin uso de isquemia (grupo A) y el bloqueo espinal y uso de manguito de isquemia (grupo B). Ambos procedimientos se calcularon mediante la evaluación de la edad, el tiempo de cirugía, el dolor transquirúrgico y a las 24 horas mediante escala EVA, el tiempo de estancia en recuperación, la necesidad de administrar anestesia general o dosis anestésica de rescate y los grados de flexión a las 24 horas en el postquirúrgico. Se utilizó prueba t de Student con un nivel de significación p < 0.05 para variables no paramétricas y χ2 para variables paramétricas. Resultados: Se incluyeron 38 pacientes por cada grupo. El tiempo quirúrgico fue de 45 contra 39 minutos (p = 0.03); el tiempo en recuperación: 1.9 contra 3 horas (p = 0.0004), el cual fue menor en el grupo A, mientras que el dolor transquirúrgico fue mayor (17 contra 3% [p = 0.09]), sin requerir anestesia general. Conclusiones: Las ventajas a favor de la anestesia intraarticular fueron: estadías hospitalarias cortas, menor dolor a las 24 horas y seguridad en su aplicación. Su desventaja es la probabilidad de dolor transquirúrgico, siendo suficiente la sedación.
Abstract: Indroduction: Knee arthroscopy is one of the most commonly performed procedures. General anesthesia and spinal blockage are the most common forms of anesthesia. We consider that this surgery can be managed with intra-articular local anesthesia, thus avoiding prolonged stays in recovery, with effective pain management and optimization of presurgical, intrasurgical and post-surgical times. Material and methods: Prospective, quasi-experimental, longitudinal study to compare two anesthetic procedures: intraarticular anesthesia (lidocaine with epinephrine, bupivacaine and fentanyl) without the use of ischemia (group A); spinal blockage and use of ischemia (group B) by assessing age, surgery time, pain during surgery and 24 hour post-op VA scale, time spent in recovery, need to administer general anesthesia or anesthetic rescue doses, 24-hour range of motion. Student t-test, significance level was used: p < 0.05 for nonparametric variables and χ2 parametric variables. Results: 38 patients were included per group. The surgical time (45 min vs 39 min, p = 0.03), recovery time (1.9 vs 3 hours, p = 0.0004) were lower in group A, while pain during surgery was greater (17 vs 3%, p = 0.09), without requiring general anesthesia. Conclusion: The advantages in favor of intraarticular anesthesia were: shortened hospital stays, less pain at 24 hours, safety in its application. Its disadvantage is the possibility of pain during surgery and sedation is sufficient as adjuvant.

Abstract Background: Intra-articular injections of platelet-rich plasma to treat symptoms of knee osteoarthritis have been successfully used in young patients. However in most of these studies the control and test knees were present in different patients thus incorporating a large amount of bias in the results. Therefore, the present study was designed in which patients with bilateral osteoarthritis knee were included and platelet-rich plasma was administered in one knee and normal saline in another knee of same patient. Methods: 20 patients aged 30-65 years with bilateral osteoarthritis knees (ASA class I and II) of either gender were included in the study. Patients were randomized to receive platelet-rich plasma and normal saline in one of the two knees. The primary outcome was VAS and WOMAC score at 6 months after procedure. The secondary outcome included changes in joint stiffness, physical function, any adverse effects noted during the course of study. Results: The baseline VAS score in platelet-rich plasma knee was 8.4 ± 0.88 which improved significantly to 4.85 ± 2.48 (p < 0.001) at 6 months as compared to normal saline knee (p = 0.017). The WOMAC pain score also improved from baseline (14.5 ± 1.3) to over 6 month 7.00 ± 4.24 (p < 0.001) in platelet-rich plasma knee while in the normal saline knee, no significant change occurred from baseline to six months (10.2 ± 1.2 to 10.05 ± 1.23). There was also significant decrease in stiffness and improvement of physical activity in the platelet-rich plasma knee as compared to normal saline knee. Conclusion: The present study showed significant decrease in pain and stiffness and improvement of physical functions of knee joint with intra-articular platelet-rich plasma injection as compared to normal saline.
Resumo Justificativa e objetivos: Injeções intra-articulares de plasma rico em plaquetas têm sido usadas com sucesso para tratar os sintomas da osteoartrite de joelho em pacientes jovens. Porém, na maioria desses estudos, os joelhos de controle e teste estavam presentes em diferentes pacientes, o que incorporou uma grande quantidade de viés aos resultados. Portanto, o projeto do presente estudo incluiu pacientes com osteoartrite em ambos os joelhos, com a administração de plasma rico em plaquetas em um dos joelhos e de solução salina normal no outro joelho do mesmo paciente. Métodos: 20 pacientes, de ambos os sexos, com idades entre 30-65 anos e portadores de osteoartrite bilateral de joelho (classificação ASA I e II) foram incluídos no estudo. Os pacientes foram randomizados para receber plasma rico em plaquetas e solução salina normal em um dos dois joelhos. O desfecho primário foram os escores VAS e WOMAC seis meses após o procedimento. O desfecho secundário incluiu alterações na rigidez articular, função física e qualquere feito adverso observado durante o curso do estudo. Resultados: O escore VAS basal para o joelho que recebeu plasma rico em plaquetas foi 8,4 ± 0,88 e melhorou significativamente para 4,85 ± 2,48 (p < 0,001) após seis meses, comparado ao joelho que recebeu solução salina normal (p = 0,017). A intensidade da dor avaliada com o WOMAC também melhorou de 14,5 ± 1,3 na fase basal para 7,00 ± 4,24 após seis meses (p < 0,001) nos joelhos que receberam plasma rico em plaquetas, enquanto nenhuma mudança significativa ocorreu nos joelhos que receberam solução salina normal entre a fase basal e após seis meses (10,2 ± 1,2 a 10,05 ± 1,23). Além disso, houve uma diminuição significativa da rigidez e melhora da atividade física nos joelhos que receberam plasma rico em plaquetas, comparados aos joelhos que receberam salina normal. Conclusão: O presente estudo identificou uma diminuição significativa da dor e da rigidez e uma melhora das funções físicas da articulação do joelho com a injeção intra-articular de plasma rico em plaquetas, comparada à solução salina normal.

Resumen: Introducción: La osteoartrosis es actualmente la quinta causa de discapacidad en el adulto. Su prevalencia aumenta a partir de los 40 años. La viscosuplementación es un tratamiento para las etapas iniciales de la osteoartrosis de rodilla. Objetivo: Comparar la eficacia y la calidad de vida en pacientes con gonartrosis sintomática tratados con ácido hialurónico de alto y mediano peso molecular. Material y métodos: Estudio analítico, retrospectivo, transversal, observacional de expedientes clínicos de pacientes con diagnóstico de gonartrosis grado II y grado III, de Octubre de 2017 a Junio de 2018, tratados con viscosuplementación con ácido hialurónico de alto o de mediano peso molecular; se analizó la calidad de vida y la escala de WOMAC de manera previa a la primera aplicación y con seguimiento a los dos, cuatro y seis meses. Resultados: 194 pacientes, con edades entre 30 y 87 años (promedio 61.85; DE = 11.3); 134 mujeres (69.1%) y 60 hombres (30.9%). En ambos grupos la evolución fue hacia la mejoría, con disminución en el puntaje WOMAC, sin diferencia significativa entre grupos. El puntaje de WOMAC tuvo un aumento mínimo pasados seis meses de la aplicación en ambos grupos, lo que se interpreta como disminución del efecto terapéutico. Dos pacientes tuvieron reacciones adversas mínimas localizadas, las cuales se resolvieron con medidas generales. Conclusión: El ácido hialurónico en ambas presentaciones, de alto y de bajo peso molecular, es efectivo en el tratamiento de la gonartrosis sintomática sin diferencia con el peso molecular.
Abstract: Introduction: OA is currently the fifth leading cause of adult disability, its prevalence increases from age 40. Viscosupplementation is a treatment for the early stages of knee OA. Objective: To compare efficacy and quality of life in patients with symptomatic gonartrosis, treated with high and low molecular weight hyaluronic acid. Material and methods: Analytical, retrospective, cross-sectional, observational study of clinical records of patients diagnosed with grade II and grade III gonarthrosis, October 2017 to June 2018, treated with viscosupplementation with high molecular weight hyaluronic acid or low molecular weight; WOMAC quality of life and scale were analyzed prior to the first application and tracked at two, four and six months. Results: 194 patients, aged between 30 to 87 years (promedio 61.85; SD = 11.3); 134 women (69.1%), 60 men (30.9%). In both groups the evolution was towards improvement, with a decrease in the WOMAC score, with no significant difference between groups. The WOMAC score had a minimum increase after 6 months of application in both groups, which is interpreted as decreasing the therapeutic effect. Two patients had localized minimal adverse reactions which were resolved with general measures. Conclusion: Hyaluronic acid in both presentations, high and low molecular weight, are effective in the treatment of symptomatic goonarthrosis without difference to molecular weight.

Introducción: El acido hialuronico intrarticular se suele utilizar con diferentes esquemas para tratar la artrosis de rodilla. Nuestro objetivo fue analizar la eficacia y el uso del acido hialuronico intrarticular en la practica habitual. Materiales y Métodos: Cohorte retrospectiva observacional. Se evaluo a 1227 pacientes con artrosis de rodilla tratados con acido hialuronico intrarticular 20 mg/2 ml/semana (76%, 20 mg) y 40 mg/2 ml (24%, 40 mg) segun la practica habitual. Seguimiento de 6 meses. Se evaluo la eficacia con la escala de Likert de 5 puntos y la proporcion de respuesta ≥50%. Resultados: La mediana de aplicaciones fue de 5 (20 mg) y 3 (40 mg). El puntaje de Likert mejoro significativamente en ambos grupos a los 6 meses. La mediana del puntaje mejoro de 4 (media 3,77 ± 0,69) al inicio a 2 (media 1,99 ± 0,76) a los 6 meses con 20 mg (p <0,001) y de 4 (media 3,65 ± 0,65) a 2 (media 1,86 ± 0,72) con 40 mg (p <0,001). La proporcion de respuesta ≥50% a los 6 meses fue del 61% y 66%, respectivamente. En el analisis multivariado, la tasa de respuesta ≥50% se asocio con un mayor puntaje inicial, edad mas joven y menor duracion de la enfermedad. Solo un paciente con 20 mg (0,1%) tuvo un episodio adverso serio (artritis septica). Conclusión: Nuestro estudio en la practica clinica comun respalda la efectividad del acido hialuronico intrarticular para tratar la artrosis de rodilla, con un beneficio clinico a los 6 meses de seguimiento. Nivel de Evidencia: IV
Background: Treatment of knee osteoarthritis with intra-articular hyaluronic acid (IA-HA) is frequently used in Argentina, with different dosing forms and injection regimens. Our main objective was to provide real world data on the use and effectiveness of IA-HA. Methods: In this observational retrospective cohort study we studied 1227 patients with knee osteoarthritis treated with IA-HA 20 mg/2 ml weekly (76%-20 mg group) and 40 mg/2 ml (24%-40 mg group) according to standard practice. Follow-up was 6 months and effectiveness was assessed by the 5-point Likert scale and a response of 50% or more. Results: Median number of injections was 5 (20 mg) and 3 (40 mg). Both groups had a significant improvement in the Likert scale from baseline to 6 months. Median score improved from 4 (mean 3.77 ± 0.69) at baseline to a median of 2 (mean 1.99 ± 0.76) at 6 months (20 mg group, p<0.001) and from a median of 4 (mean 3.65 ± 0.65) to a median of 2 (mean 1.86 ± 0.72) in the 40 mg group, p<0.001. The percentages of patients with a response of 50% or more at 6 months were 61% and 66%, respectively. In the multivariate analysis, the 50% response rate was associated with a higher baseline score, younger age and shorter duration of disease. Only one patient in the 20 mg group (0.1%) experienced a serious treatment-related adverse event (septic arthritis) following injection. Conclusion: Our study carried out during routine clinical practice supports the effectiveness of IA-HA for the management of knee osteoarthritis with a clinical advantage observed at a 6-month follow-up.

Background: In patients with hemophilia, radionuclide synoviorthesis, or the intra-articular injection of a radionuclide to decrease the synovial hypertrophy tissue, aims to decrease or avoid hemarthrosis. Aim: To evaluate the effectiveness of radionuclide synoviorthesis in hemophilia. Material and Methods: Observational retrospective study of the evolution of 107 male patients aged 3 to 54 years who were subjected to radionuclide synoviorthesis between 2007 and 2015. Results: Of 164 treated joints, in 65% treatment was successful, (defined as zero to two hemarthroses and absence of synovitis during the follow up period), in 17% it was partially successful (defined as two or less hemarthroses, but persistence of the synovitis) and failed in 18% of the procedures. No important complications were recorded. Conclusions: Radionuclide synoviorthesis has an overall 82% success rate, is minimally invasive, can be used at any age and is inexpensive We recommend its implementation in Chilean hemophilia treatment centers.
