An Assessment of Ankle Function, Oxidative Damage, and Inflammatory Factor Levels in Minimally Invasive Ankle Joint Fusion Surgery for the Treatment of Traumatic Ankle Osteoarthritis

SUMMARY: Traumatic ankle osteoarthritis is a degenerative condition resulting from traumatic injuries. The objective of this study was to evaluate the impact of minimally invasive ankle joint fusion surgery on ankle function, oxidative damage, and inflammatory factor levels in traumatic ankle osteoarthritis patients. A total of 112 traumatic ankle osteoarthritis patients treated in our hospital from January 2022 to January 2023 were enrolled. They were randomly rolled into a control group (Group C) and an experimental group (Group E), with the former undergoing conventional open ankle joint fusion surgery and the latter receiving minimally invasive ankle joint fusion surgery. A comparison was made between the two groups based on American Orthopedic Foot and Ankle Society (AOFAS), bony fusion rates, and visual analog scale (VAS) scores at pre-operation, and at 1, 2, and 3 months post-operation. Additionally, serum oxidative damage indicators and inflammatory factor levels were measured to evaluate the recovery effects in both groups. Relative to Group C, Group E showed drastically increased AOFAS scores and bony fusion rates (P<0.05), as well as greatly decreased VAS scores (P<0.05). Moreover, Group E exhibited more pronounced improvements in oxidative damage indicators and inflammatory factors versus Group C (P<0.05). Minimally invasive ankle joint fusion surgery drastically improves ankle function in traumatic ankle osteoarthritis patients and reduces levels of oxidative damage and inflammatory response. This provides an important clinical treatment option.

La osteoartritis traumática del tobillo es una afección degenerativa resultante de lesiones traumáticas. El objetivo de este estudio fue evaluar el impacto de la cirugía mínimamente invasiva de fusión de la articulación talocrural sobre la función del tobillo, el daño oxidativo y los niveles de factor inflamatorio en pacientes con osteoartritis traumática del tobillo. Se inscribieron un total de 112 pacientes con artrosis traumática de tobillo tratados en nuestro hospital desde enero de 2022 hasta enero de 2023. Fueron divididos aleatoriamente en un grupo de control (Grupo C) y un grupo experimental (Grupo E), donde el primero se sometió a una cirugía de fusión de la articulación talocrural abierta convencional y el segundo recibió una cirugía de fusión de la articulación talocrural mínimamente invasiva. Se realizó una comparación entre los dos grupos según la Sociedad Estadounidense de Ortopedia de Pie y Tobillo (AOFAS), las tasas de fusión ósea y las puntuaciones de la escala visual analógica (EVA) antes de la operación y 1, 2 y 3 meses después de la operación. Además, se midieron los indicadores de daño oxidativo sérico y los niveles de factor inflamatorio para evaluar los efectos de la recuperación en ambos grupos. En relación con el grupo C, el grupo E mostró puntuaciones AOFAS y tasas de fusión ósea drásticamente aumentadas (P <0,05), así como puntuaciones VAS muy disminuidas (P <0,05). Además, el grupo E exhibió mejoras más pronunciadas en los indicadores de daño oxidativo y factores inflamatorios en comparación con el grupo C (P <0,05). La cirugía de fusión de la articulación talocrural mínimamente invasiva mejora drásticamente la función del tobillo en pacientes con osteoartritis traumática del tobillo y reduce los niveles de daño oxidativo y la respuesta inflamatoria. Esto proporciona una importante opción de tratamiento clínico.

Bone protective effect of sinomenine against monosodium iodoacetate induced knee and hip injury in rat model: an inflammatory pathway

Purpose: Osteoarthritis (OA) is a degenerative joint disease which is categorized via destruction of joint cartilage and it also affects the various joints, especially knees and hips. Sinomenine active phytoconstituents isolated from the stem of Sinomenium acutum and already proof anti-inflammatory effect against the arthritis model of rodent. In this experimental protocol, we scrutinized the anti-osteoarthritis effect of sinomenine against monosodium iodoacetate (MIA) induced OA in rats. Methods: MIA (3 mg/50 µL) was used for inducing the OA in the rats, and rats received the oral administration of sinomenine (2.5, 5 and 7.5 mg/kg body weight) up to the end of the experimental study (four weeks). The body and organs weight were estimated. Aggrecan, C-terminal cross-linked telopeptide of type II collagen (CTX-II), glycosaminoglycans (GCGs), monocyte chemoattractant protein-1 (MCP-1), Interferon gamma (IFN-γ), antioxidant, inflammatory cytokines, inflammatory mediators and matrix metalloproteinases (MMP) were analyzed. Results: Sinomenine significantly (P < 0.001) boosted the body weight and reduced the heart weight, but the weight of spleen and kidney remain unchanged. Sinomenine significantly (P < 0.001) reduced the level of nitric oxide, MCP-1 and improved the level of aggrecan, IFN-γ and GCGs. Sinomenine remarkably upregulated the level of glutathione, superoxide dismutase and suppressed the level of malonaldehyde. It effectually modulated the level of inflammatory cytokines and inflammatory mediators and significantly (P < 0.001) reduced the level of MMPs, like MMP-1, 2, 3, 9 and 13. Conclusions: Sinomenine is a beneficial active agent for the treatment of OA disease.

Effect of Dioscorea villosa extract and the phytoestrogen diosgenin on ovariectomized mice with zymosan-induced arthritis

Abstract Humans are exposed to natural compounds such as phytoestrogens primarily through diet and supplements. These compounds promote health by alleviating the symptoms and illnesses associated with menopause and arthritis. Diosgenin (DSG) occurs naturally in plants such as Dioscorea villosa (DV) and binds to estrogen receptors, so it may have similar effects to this hormone, including against arthritis. Thus, we investigated the effect of chronic treatment with dry extract of DV and its phytoestrogen DSG on ovariectomized mice with arthritis. We found that dry extract of Dioscorea villosa (DV) contains the phytoestrogen diosgenin (DSG) in its composition. Furthermore, arthritic mice treated with DV and DSG showed reduced neutrophil accumulation in the articular cartilage. Also, the dry extract of DV administered orally (v.o) did not alter the leukocyte count in the joints or promote changes in the reproductive tract. However, DSG altered these parameters, with possible beneficial effects by reducing symptoms related to reproductive aging. Thus, oral treatment with dry extract of DV and subcutaneous (s.c) treatment with DSG showed promise by acting against inflammation caused by arthritis and reducing symptoms in the reproductive tract due to menopause.

Transtibial Femoral Tunnel Technique in ACL Reconstruction and Osteoarthritis Incidence / Técnica do túnel femoral transtibial na reconstrução do LCA e incidência de osteoartrite

Abstract Objective: Evaluate osteoarthritis incidence in patients that undergone ACL reconstruction using the transtibial technique, with a minimum of 5 years of follow up, with isolated ACL injury. Methods: Patients who underwent ACL reconstruction by the same surgeon using the transtibial technique with hamstrings graft and with a minimum of 5 years of follow-up, without other injuries during the surgical procedure, were selected to undergo imaging exams of the operated knee to assess the incidence of osteoarthritis. The obtained data were evaluated by descriptive statistics. Results: Forty-two patients (44 knees) were evaluated, with a mean age of 31 years old (SD: 8), being 23 right knees and 28 male patients. Mean time from surgery to imaging evaluation was 94.1 months (ranging from 60 to 154 months; SD: 28). Of the evaluated knees, 37 did not have osteoarthritis (83.3%) and 7 had (16.7%). Conclusion: ACL reconstruction with femoral tunnel performed through the transtibial technique in patients without other associated injuries in the operated knee, using hamstrings graft, with a minimum of 5 years of follow up, showed an osteoarthritis incidence of 16.7% in a mean follow-up of 94.1 months.

Minimally Invasive Tibiotalocalcaneal Arthrodesis with Blocked Retrograde Intramedullary Nail - Report of Three Cases / Artrodese tibiotalocalcaneana minimamente invasiva com haste intramedular retrógrada bloqueada - Relato de três casos

Abstract Ankle osteoarthritis (AOA) is associated with pain and variable functional limitation, demanding clinical treatment and possible surgical indication when conservative measures are ineffective - arthrodesis has been the procedure of choice, because it reduces pain, restores joint alignment and makes the segment stable, preserving gait. The present study reports 3 cases (3 ankles) of male patients between 49 and 63 years old, with secondary AOA, preoperative American Orthopaedic Foot and Ankle Society Ankle-Hindfoot Scale (AOFAS AHS) of 27 to 39 points, treated by minimally invasive tibiotalocalcaneal arthrodesis using blocked retrograde intramedullary nail. Hospital stay was of 1 day, and the patients were authorized for immediate loading with removable ambulation orthotics, as tolerated. The physical therapy treatment, introduced since hospitalization, was maintained, prioritizing gait training, strength gain, and proprioception. Clinical and radiographic follow-up was performed at weeks 1, 2, 6, 12 and 24. After evidence of consolidation (between the 6th and 10th weeks), the orthotics were removed. One patient complained of pain in the immediate postoperative period and, at the end of the 1st year, only one patient presented pain during rehabilitation, which was completely resolved with analgesics. Currently, the patients do not present complaints, returning to activities without restrictions - one of them, to the practice of soccer and rappelling. The postoperative AOFAS AHS was from 68 to 86 points.

Resumo A osteoartrite do tornozelo (OAT) está associada a quadro álgico e limitação funcional variável, demandando tratamento clínico e eventual indicação cirúrgica quando as medidas conservadoras são inefetivas - a artrodese tem sido o procedimento de escolha, por reduzir a dor, restaurar o alinhamento articular e tornar o segmento estável, preservando a marcha. O presente estudo relata 3 casos (3 tornozelos) de pacientes do sexo masculino, com entre 49 e 63 anos de idade, portadores de OAT secundária, American Orthopaedic Foot and Ankle Society Ankle-Hindfoot Scale (AOFAS AHS, na sigla em inglês) pré-operatória de 27 a 39 pontos, tratados mediante artrodese tibiotalocalcaneana minimamente invasiva utilizando haste intramedular retrógrada bloqueada. A permanência hospitalar foi de 1 dia, e os pacientes foram autorizados para carga imediata com órteses removíveis para deambulação, conforme tolerado. O tratamento fisioterápico, introduzido desde o internamento, foi mantido, priorizando-se treino de marcha, ganho de força e propriocepção. Foi realizado acompanhamento clínico e radiográfico nas semanas 1, 2, 6, 12 e 24. Após evidências de consolidação (entre a 6ª e a 10ª semanas), as órteses foram retiradas. Um paciente queixou-se de dor no pós-operatório imediato e, ao final do 1° ano, apenas 1 paciente apresentou dor durante a reabilitação, resolvida completamente com analgésicos. Atualmente, os pacientes não apresentam queixas, retornando às atividades sem restrições - um deles, à prática de futebol e rapel. A AOFAS AHS pós-operatória foi de 68 a 86 pontos.

Carpectomía de la fila proximal en procesos degenerativos de la muñeca. Nuestra experiencia a mediano plazo / Proximal row carpectomy in degenerative wrist conditions. Our medium-term experience

Objetivo: Evaluar los resultados clínico-radiográficos a mediano plazo del tratamiento de los procesos degenerativos de la muñeca mediante carpectomía proximal. Materiales y Métodos: Estudio descriptivo retrospectivo de 33 pacientes operados entre 2009 y 2019 en nuestro Centro. Se evaluaron el rango de movilidad, el dolor con la escala analógica visual y la capacidad funcional con el cuestionario QuickDASH. Se realizaron pruebas de valoración biomecánica. Se estudió la incidencia de complicaciones y de una segunda intervención. Se evaluó la progresión radiográfica de la artrosis y su asociación con los malos resultados clínicos. Resultados:El seguimiento medio fue de 10 años. El rango de movilidad medio fue de 77,11° en el arco de flexo-extensión y 36,7° en el radiocubital. El puntaje medio de dolor evolucionó de 7,9 a 2,7 tras la cirugía (p <0,003). El puntaje QuickDASH en el último control fue de 24,3. Se halló una asociación inversa entre el grado de artrosis radiocarpiana preoperatoria y el resultado clínico (p <0,03); sin embargo, no hubo una relación entre la evolución artrósica radiográfica posoperatoria con la mala evolución (p <0,04). Cuatro pacientes necesitaron una segunda intervención mediante artrodesis total de muñeca. Conclusiones: La carpectomía proximal es una opción terapéutica que ofrece resultados satisfactorios a mediano plazo en pacientes con procesos degenerativos de la muñeca, proporciona un adecuado rango de movilidad con una baja tasa de complicaciones. El uso de esta técnica en pacientes con degeneración articular de mayor grado antes de la cirugía puede llevar a un peor resultado clínico. Nivel de Evidencia: IV

Objective: Examining the medium-term clinical and radiological outcomes of proximal carpectomy for treating degenerative wrist conditions. Materials and Methods:Retrospective study of 33 patients who underwent proximal carpectomy between 2009 and 2019. Outcomes were assessed through range of motion measurements, pain evaluation using the Visual Analog Scale (VAS), and functional capacity using the Quick-DASH questionnaire. Biomechanical tests were performed and the rate of complications and reoperations was analyzed. Radiological progression of osteoarthritis and its impact on clinical outcomes were examined. Results: The mean range of motion was 77.11º (range 51­80º) in flexion-extension and 36.7º (range 29­42º) in radioulnar deviation. VAS scores improved significantly from 7.9 (range 7­9) to 2.7 (range 0­7) post-surgery (p<0.003). The Quick-DASH score at the final follow-up was 24.3 (range 11­45). We observed an inverse relationship between preoperative radiocarpal osteoarthritis severity and clinical outcomes (p<0.03), but no link between postoperative osteoarthritis progression and poor outcomes (p<0.04). Four patients (12.12%) required reoperation with total wrist arthrodesis. Conclusions:Proximal carpectomy demonstrates satisfactory medium-term outcomes for degenerative wrist conditions, offering good range of motion and a low complication rate. However, patients with more severe preoperative joint degeneration may lead to poorer clinical outcomes. Level of Evidence: IV

Compromiso de las articulaciones vecinas en la evolución alejada de la artrodesis de tobillo / Compromise of adjacent joints in long-term evolution of ankle arthrodesis

Introducción: La artrodesis tibioastragalina es una opción para tratar la artrosis de tobillo en pacientes que no responden a las medidas conservadoras. Su principal desventaja es el compromiso a mediano y largo plazo de las articulaciones vecinas. Objetivo: Determinar el compromiso de las articulaciones vecinas a mediano y largo plazo, y su impacto sobre los resultados funcionales en los pacientes con artrodesis de tobillo. Materiales y Métodos: Se evaluó a una serie de 11 pacientes (6 mujeres y 5 hombres). El diagnóstico inicial era artrosis postraumática (9 casos), artritis séptica (1 caso) y lesión osteocondral de astrágalo (1 caso). El promedio de edad al operarse era de 50 años. La media de seguimiento fue de 9 años. Se evaluó el compromiso radiográfico de las articulaciones vecinas. La función se valoró mediante la escala analógica visual para dolor, la escala de la AOFAS y un cuestionario simple de satisfacción. Resultados: Diez pacientes (91%) tenían artrosis en alguna de las articulaciones vecinas. El puntaje medio en la escala analógica visual fue de 2,6 y el de la escala de la AOFAS, de 71. Nueve refirieron estar muy satisfechos; uno, medianamente satisfecho y otro se manifestó insatisfecho. Conclusión: El compromiso de las articulaciones vecinas es muy frecuente a largo plazo, pero esto no repercute directamente en los resultados funcionales. Nivel de Evidencia: IV

Introduction: Tibiotalar arthrodesis is an option in the treatment of ankle osteoarthritis in patients who do not respond to conservative measures. Its main disadvantage is the compromise of adjacent joints in the medium and long term. Objective: To determine the involvement of adjacent joints in the medium and long term and its impact on functional outcomes in patients with ankle arthrodesis. Materials and Methods: We evaluated a series of 11 patients, 6 females and 5 males. The initial diagnosis was post-traumatic osteoarthritis (9 cases), septic arthritis (1 case), and osteochondral lesion of the talus (1 case). The mean age at the time of surgery was 50 years. The mean follow-up was 9 years. The radiographic compromise of the adjacent joints was evaluated. The patients were functionally evaluated using the Visual Analog Pain Scale (VAS), the AOFAS scale (American Orthopedic Foot and Ankle Score), and a simple satisfaction questionnaire. Results: 10 patients (91%) presented with osteoarthritis of one of the adjacent joints. The average score on the VAS was 2.6, while on the AOFAS scale, it was 71. Nine patients reported being very satisfied, one was moderately satisfied, and one was dissatisfied. Conclusion: The involvement of adjacent joints is very frequent in the long term, but this does not have a direct impact on the patient's functional outcomes. Level of Evidence: IV

Introduction: Supramalleolar osteotomies are a treatment option for asymmetric ankle osteoarthritis. Our work aims to describe the clinical, radiographic, and subjective outcomes obtained in patients with ankle osteoarthritis who underwent a supramalleolar osteotomy (SMOT). Materials and methods: Retrospective, observational, and descriptive study on patients who underwent SMOT for ankle osteoarthritis between January 2010 and July 2017. The patients' clinical records were analyzed. Results: We included 13 patients who underwent SMOT, 8 patients with valgus (61.5%) and 5 (38.5%) with varus rearfoot and ankle misalignment. The mean varus VAS score decreased from 9 ± 0.45 to 3 ± 1 postoperatively (p <0.05) and, in valgus deformities, from a mean 7.88 ± 0.35 to 2.15 ±1.64 postoperatively (p <0.05). The mean AOFAS score changed from 32.8 ± 16.2 to 82.1 ± 13.6 postoperatively in the varus deformity group (p <0.05) and from 31 ± 17.3 preoperatively to 93.1 ± 6.20 postoperatively in the valgus deformity group (p <0.05). Twelve patients (92.3%) achieved radiographic union in an average time of 10.4 weeks. Conclusion:Supramalleolar osteotomy as a treatment for asymmetric ankle osteoarthritis is a predictable technique with very good clinical and radiological outcomes in the short and medium term.

The Influence of Tunnel Parameters and Graft Inclination Angle on Clinical and Radiological Outcome at Long-term Follow-up after Arthroscopic Anterior Cruciate Ligament Reconstruction / Influência dos parâmetros do túnel e do ângulo de inclinação do enxerto no desfecho clínico e radiológico no acompanhamento de longo prazo após a reconstrução artroscópica do ligamento cruzado anterior

Abstract Objective To study the influence of various tunnel parameters and graft inclination angle (GIA) on the clinical and radiological outcome after anterior cruciate ligament reconstruction (ACLR) at long-term follow-up. Methods In this retrospective study, 80 patients with isolated anterior cruciate ligament (ACL) injury treated by single bundle ACLR using bone patellar tendon bone (BPTB) and hamstring (HT) autografts were evaluated clinically and radiologically at their long-term follow-up. The study population were divided into two groups based on ideal and nonideal tunnel parameters as well as ideal and nonideal GIA. The various tunnel parameters and GIA were interpreted with clinical and radiological outcome at long-term follow-up. Results Eighty patients, 36 (45%) using BPTB and 44 (55%) using HT autografts, were available to complete the study. Patients with ideal coronal tibial tunnel angle (CTTA) and coronal femoral tunnel angle (CFTA) show superior clinical outcome (pivot shift test) than nonideal CTTA and CFTA, which was found to be statistically significant (p-value < 0.038 and 0.024, respectively). Similarly, patients with ideal coronal tibial tunnel position (CTTP) show superior clinical outcome (International Knee Documentation Committee - IKDC objective) over nonideal CTTP (p-value < 0.017). All other tunnel parameters and GIA were not found to have influence on clinical outcome. None of the tunnel parameters have influenced osteoarthritis (OA) change. There was no progression of OA change in the study population at long-term follow-up after ACLR. Conclusion Ideal coronal tunnel parameters produced a better clinical outcome at long-term follow-up after ACLR. There was no progression of OA change at long-term follow-up after isolated ACLR.

Resumo Objetivo O objetivo deste estudo foi analisar a influência de vários parâmetros do túnel e do ângulo de inclinação do enxerto (GIA, do inglês graft inclination angle) nos desfechos clínicos e radiológicos da reconstrução do ligamento cruzado anterior (RLCA) no acompanhamento de longo prazo. Métodos Neste estudo retrospectivo, 80 pacientes com lesão isolada do ligamento cruzado anterior (LCA) submetidos à RLCA de feixe único com autoenxertos de tendão patelar ósseo (TPO) e isquiotibiais (IT) foram avaliados clínica e radiologicamente durante o acompanhamento em longo prazo. A população do estudo foi dividida em dois grupos com base nos parâmetros ideais ou não ideais do túnel, bem como no GIA ideal e não ideal. Os vários parâmetros do túnel e o GIA foram interpretados com os desfechos clínicos e radiológicos no acompanhamento em longo prazo. Resultados Oitenta pacientes, sendo 36 (45%) submetidos ao procedimento com autoenxertos de TPO e 44 (55%) com autoenxertos IT, puderam completar o estudo. Pacientes com ângulo do túnel tibial coronal (ATTC) e ângulo do túnel femoral coronal (ATFC) ideais apresentam resultados clínicos superiores (teste de pivot shift) do que aqueles com ATTC e ATFC não ideais, sendo a diferença estatisticamente significativa (valor de p < 0,038 e 0,024, respectivamente). Da mesma forma, pacientes com posição do túnel tibial coronal (PTTC) ideal apresentam resultado clínico superior (International Knee Documentation Committee [IKDC] objetivo) em relação àqueles com PTTC não ideal (valor de p < 0,017). Os demais parâmetros do túnel e o GIA não influenciaram o desfecho clínico. Nenhum dos parâmetros do túnel influenciou a alteração associada à osteoartrite (OA). Não houve progressão da alteração da OA na população do estudo no acompanhamento em longo prazo após a RLCA. Conclusão Os parâmetros ideais do túnel coronal produziram um melhor desfecho clínico no acompanhamento de longo prazo após a RLCA. Não houve progressão da alteração da OA no acompanhamento em longo prazo após a RLCA isolada.

Objetivo:Investigar a contribuição da microbiota intestinal e dos componentes dietéticos, naperspectiva dediminuir as patologias associadas à osteoartrite. Metodologia:Trata-se de uma revisão integrativa desenvolvida a partir da seleção de artigos disponíveis escritos nalíngua inglesa, publicados nas bases de dados Pubmed e Science Direct. Resultados:No total, 25.583 artigos foram encontrados na busca, após os critérios de exclusão, 19 artigos compuseram o corpo de análise da revisão. Pesquisas em animais mostram que os efeitos induzidos por dieta rica em gordura foram evidentes e indicaram uma inflamação sistêmica de baixo grau resultando no agravamento da oesteoartritepor meio do aumento da degeneração da cartilagem. Dado ao impacto potencial da dieta na oesteoartrite, foram realizados estudos para avaliar a dieta mediterrânea, os níveis de ômega 3 e 6, vitamina C e E, com destaque para a oligofrutose, uma abordagem nova para tratar a oesteoartriteda obesidade. Conclusões:Conclui-se que apesar de já existir alguma evidência da utilidade da nutrição por meioda dieta alimentar como complemento da terapêutica na osteoartrite são necessários mais estudos que comprovem as intervenções na redução máxima dos marcadores inflamatórios ocasionando o alíviodos sintomas em pacientes com oesteoartrite (AU).

Introduction:Osteoarthritis is a degenerative disease characterized by progressive deterioration of the articular cartilage, resulting in pain and total joint disability in advanced stages. It is considered one of the most common joint disorders worldwide and its prevalence is steadily increasing due to aging, inflammatory diets and physical inactivity. Objective:The aim of this literature review was to investigate the contribution of intestinal microbiota and dietary components to try to reduce the pathologies associated with osteoarthritis.Methodology:This is an integrative review, developed from the selectionof available articles written in English, published in the Pubmed and Science Direct databases. Results:Intotal, 25.583articleswerefoundinthesearch,aftertheexclusioncriteria,19 articles madeupthebodyofanalysisofthereview.Animal research shows that the effects induced by a high-fat diet were evident and indicated low-grade systemic inflammation resulting in worsening osteoarthritis by increasing cartilage degeneration. Given the potential impact of diet on osteoarthritis, studies have been conducted to evaluate the Mediterranean diet, omega 3 and 6 levels, vitamin C and E, especially oligofructose, a new approach to treat obesity osteoarthritis.Conclusions:It is concluded that although there is already some evidence of the usefulness of nutrition through the diet as a complement to therapy in osteoarthritis, further studiesare needed to prove the interventions in the maximum reduction of inflammatory markers will cause the relief of symptoms in patients with osteoarthritis (AU).

Resultados: La severidad de la erosión condilar presenta alta correlación positiva entre las clasificaciones Alexiou/Arayasantiparb (rho=0,986) y baja entre Cömert/Alexiou (rho=0,421) y Cömert/Arayasantiparb (rho=0,422). La esclerosis condilar presentó fuerte correlación entre las clasificaciones de Cömert/Alexiou, Masilla/Alexiou y Cömert/Masilla (rho=857;rho=0,853;rho=0,998). Los datos presentaron alta consistencia interna (Alfa Cronbach=0,897) y baja validación de contenido (36,2%). Conclusiones: Las mediciones de los 7 sistemas presentan alta fiabilidad. La erosión ósea, esclerosis y osteofitos son medidos en cuatro niveles de severidad y con similar escala en tres sistemas de diagnóstico (Alexiou, Arayasantiparb y Cömert), sugiriendose complementar con determinación del espacio articular y movilidad condilar, como propone RDC/TMD para TTM. La validación de contenido fue baja, solo los sistemas diagnósticos de Cömert y Alexiou superaron el 50%.

Objective: To compare and validate diagnostic systems for the severity of Osteoarthrosis (OA) of the temporomandibular joints (TMJ) in computed tomography (CT) images. Method: An observational, retrospective, analytical, blinded, retrospective study was performed. Ninety-nine patients (198MSCT-ATM) were evaluated, applying the criteria of seven different diagnostic systems. A calibrated clinician (K=0.7) performed the evaluations. Content validity was performed under the Ahmad criteria. Internal consistency was determined with Cronbach's Alpha. Data were correlated with Spearman's Rho. Results: For condylar erosion severity, there was a high positive correlation between Alexiou/Arayasantiparb (rho=0.986) and a low one between Cömert/Alexiou (rho=0.421) and Cömert/Arayasantiparb (rho=0.422) classifications. For condylar sclerosis, we found a strong correlation between Cömert/Alexiou, Masilla/Alexiou and Cömert/Masilla classifications (rho=857; rho=0.853; rho=0.998). The data presented high internal consistency (Cronbach's alpha=0.897) and low content validation (36.2%). Conclusions: The measurements of the 7 systems have a high reliability. Bone erosion, sclerosis and osteophytes are measured at four levels of severity and with a similar scale in three diagnostic systems (Alexiou, Arayasantiparb and Cömert). We suggest to complement it with the determination of joint space and condylar mobility, as proposed by RDC/TMD. Content validity was low, only the Cömert and Alexiou diagnostic systems were higher than 50%.

Differences According to the Type of Exogenous Hyaluronic Acid and its Frequency of Infiltration in the Treatment of Temporomandibular Osteoarthritis / Diferencias Según el Tipo de Ácido Hiaurónico Exógeno y su Frecuencia de Infiltración en el Tratamiento de la Osteoartritis Temporomandibular

SUMMARY: One of the most important minimally invasive treatments today in temporomandibular joint osteoarthritis (TMJ- OA) is the intra-articular exogenous hyaluronic acid (HA) injection, which has yielded good results in pain relief and improves mandibular function with few side effects. However, the effectiveness of HA continues to be controversial, partly due to the heterogeneity in the injection protocols in their molecular weight, viscosity and frequency of infiltration, among other properties. The aim of this review is to identify the differences in the histological and clinical effects of the different types of HA and the frequency of infiltration on TMJ-OA treatment. Materials and methods: A bibliographic search was performed in the PubMed, Web of Science and Scopus databases. The search was limited up to September 2022. Search terms included "osteoarthritis", "hyaluronic acid, "molecular weight", "concentration", "viscosity", "dose" and "temporomandibular", using AND/OR as Boolean terms. Results: Exogenous HA in its different molecular weights offers an improvement in histological and clinical characteristics. Apparently, low and medium molecular weight HA presents better results. No clinical studies related to the degree of HA viscosity were found. Respect to the frequency of infiltration, single injection, weekly injections for 3 weeks, weekly injections for 5 weeks and other protocols are used. However, their comparison is complex. There seems to be differences in the effects of the different HA preparations for the treatment of TMJ-OA, mainly in their molecular weight. However, the evidence remains scant.

Uno de los tratamientos mínimamente invasivos más importantes en la actualidad en la artrosis de la articulación temporomandibular (OATM) es la inyección intraarticular de ácido hialurónico (AH) exógeno, que ha dado buenos resultados en el alivio del dolor y mejora la función mandibular con pocos efectos secundarios. Sin embargo, la efectividad del AH continúa siendo controversial, en parte debido a la heterogeneidad en los protocolos de inyección en cuanto a su peso molecular, viscosidad y frecuencia de infiltración, entre otras propiedades. El objetivo de esta revisión fue identificar las diferencias en los efectos histológicos y clínicos de los diferentes tipos de HA y la frecuencia de infiltración en el tratamiento de TMJ-OA. Se realizó una búsqueda bibliográfica en las bases de datos PubMed, Web of Science y Scopus. La búsqueda se limitó hasta septiembre de 2022. Los términos de búsqueda incluyeron "osteoartritis", "ácido hialurónico", "peso molecular", "concentración", "viscosidad", "dosis" y "temporomandibular", utilizando AND/OR como términos booleanos. El HA exógeno en sus diferentes pesos moleculares ofrece una mejora en las características histológicas y clínicas. Aparentemente, el AH de bajo y medio peso molecular presenta mejores resultados. No se encontraron estudios clínicos relacionados con el grado de viscosidad del HA. Respecto a la frecuencia de infiltración, se utilizan inyecciones únicas, inyecciones semanales durante 3 semanas, inyecciones semanales durante 5 semanas y otros protocolos. Sin embargo, su comparación es compleja. Parece haber diferencias en los efectos de las diferentes preparaciones de HA para el tratamiento de la OA-TMJ, principalmente en su peso molecular. Sin embargo, la evidencia sigue siendo escasa.

Histological effect of platelet-rich plasma on temporomandibular joint osteoarthritis: systematic review in animal models

SUMMARY: The aim of this systematic review was to assess the histological effects of platelet-rich plasma (PRP) on temporomandibular joint osteoarthritis (TMJ-OA) in animal models. A systematic search was performed using PubMed, WoS, EMBASE, Science Direct and SCOPUS databases. The inclusion criteria were experimental studies in animal models that evaluated the use of PRP as a treatment for TMJ-OA with or without arthrocentesis/arthroscopy. Comparison was made to a healthy control group or to other treatment. The variables evaluated were the histological effects of the treatments, characteristics of the primary articles, characteristics of the sample studied and the risk of bias. The systematic search identified 120 studies. Eventually 5 studies were included in the analysis. Four of the studies showed a statistically significant repair in joint tissues and improvement of cartilage thickness in animals treated with PRP. The global risk of bias was unclear. The results of this systematic review suggest that PRP treatment in TMJ-OA has benefits at the histological level in cartilage, articular disc and articular bone tissue in animal models. However, due to the low number of studies and the risk of bias, further research is needed to recommend its use.

El objetivo de esta revisión sistemática fue evaluar los efectos histológicos del plasma rico en plaquetas (PRP) en la osteoartritis de la articulación temporomandibular (ATM-OA) en modelos animales. Se realizó una búsqueda sistemática en las bases de datos PubMed, WoS, EMBASE, Science Direct y SCOPUS. Los criterios de inclusión fueron estudios experimentales en modelos animales que evaluaran el uso de PRP como tratamiento para la ATM-OA con o sin artrocentesis/ artroscopia. La comparación se realizó con un grupo de control sano o con otro tratamiento. Las variables evaluadas fueron los efectos histológicos de los tratamientos, las características de los artículos primarios, las características de la muestra estudiada y el riesgo de sesgo. La búsqueda sistemática identificó 120 estudios. Finalmente se incluyeron 5 estudios en el análisis. Cuatro de los estudios mostraron una reparación estadísticamente significativa en los tejidos articulares y una mejora del grosor del cartílago en los animales tratados con PRP. El riesgo global de sesgo fue incierto. Los resultados de esta revisión sistemática sugieren que el tratamiento con PRP en la ATM-OA tiene beneficios a nivel histológico en el cartílago, el disco articular y el tejido óseo articular en modelos animales. Sin embargo, debido al escaso número de estudios y al riesgo de sesgo, se necesitan investigaciones adicionales para recomendar su uso.

Nuevas estrategias tecnológicas para la administración de fármacos en el tratamiento de patologías articulares / New technological strategies for drug administration in the treatment of joint pathologies

Despite the availability of drugs and pharmaceutical forms for the treatment of rheumatoid arthritis and osteoarthritis symptoms, their adverse effects and lack of response to therapy reinforces the need to search for new technological formulation strategies capable of delaying the progress of the disease, with better therapeutic results and prolonged control of arthropathy. The aim of this bibliographic review was to identify new reported therapeutic approaches for these diseases. The treatment of rheumatoid arthritis and osteoarthritis is an unresolved challenge, due to the complexity of these diseases. Thus, the new therapies aim to suppress inflammatory mediators and to reduce the degradation of the extracellular matrix. In addition, the use of nano and microtechnology takes advantage of the properties of polymers, lipids, peptides, and nucleic acids to develop controlled drug release systems, aiming to obtain highly effective precision therapies, whose usefulness should be evaluated in future clinical trials.

Utilização da cannabis sativa para tratamento de dor crônica em cães / Use of cannabis sativa for the treatment of chronic pain in dogs / Uso de cannabis sativa para el tratamiento del dolor crónico en perros

A Cannabis sativa é uma planta que apresenta vários benefícios terapêuticos para animais, como tratamento da dor neuropática, inflamatória e osteoartrose. A dor é bastante recorrente na rotina clínica, sendo importante seu manejo para que seja ofertada uma melhor qualidade e conforto de vida para o paciente. O estudo objetivou identificar, a partir de evidências científicas, as características da utilização medicinal do uso de Cannabis Sativa no tratamento da dor crônica no cão, utilizando um dos seus princípios ativos, canabidiol (CBD). Foi feito uma revisão bibliográfica onde foi realizada a busca de estudos experimentais e relatos de caso em bases de dados eletrônicos, sendo incluídas fontes contendo a utilização do CBD em animais, que abordaram controle da dor, assim como escore avaliativo da dor antes, durante e após o tratamento proposto. Após eleger e analisar 54 estudos percebe-se que na medicina veterinária o uso do canabidio é insuficiente, uma vez que o foco da maior parte dos estudos clínicos é voltado para medicina humana. Ainda assim, a utilização de CBD mostrou-se eficaz, confirmando uma nova alternativa para o controle da dor em animais.(AU)
