ABSTRACT

OBJECTIVE: To verify whether the use of Hylan G-F20 improves saline lavage and triamcinolone injection results in the treatment of hip osteoarthritis (HOA). METHODS: 82 patients with HOA categorized as grades II and III severity, according to Kellgren and Lawrence criteria, were randomized into the groups: lavage and triamcinolone (G0); lavage, triamcinolone, and 2 mL of hylan G-F20 (G1); lavage, triamcinolone, and 4mL of hylan G-F20 (G2); lavage, triamcinolone, and 6mL of hylan G-F20 (G3). The VAS, range of motion (ROM), WOMAC, and Lequesne questionnaires were administered at baseline, one, three, six, and twelve months post-injection. RESULTS: All groups showed clinically relevant improvements (> 20%) between baseline and first month post-injection, maintaining subjective results throughout the study period (p < 0.001). We found no differences between groups in any subjective evaluations (p > 0.05, for all). G2 and G3 obtained improved flexion results up to a year (p = 0.028). Hylan groups presented an improved external rotation since the first postoperative month and maintained the results up to a year (G1, p = 0.041; G2, p = 0.007), whereas G0 showed no improvement (p = 0.336). CONCLUSION: Hip lavage and triamcinolone injection, with or without the use of hylan, improves pain, function, and quality of life up to a year in HOA. Hylan may improve ROM up to one year. Level of Evidence IB, Randomized clinical trial.


OBJETIVO: Verificar se o Hylan G-F20 melhora os resultados da lavagem e injeção de triancinolona na osteoartrite do quadril (OAQ). MÉTODOS: 82 pacientes com HOA Kellgren e Lawrence graus II e III foram randomizados: lavagem e triamcinolona (G0); lavagem, triancinolona e 2 mL de Hylan G-F20 (G1); lavagem, triamcinolona e 4 mL de Hylan G-F20 (G2); lavagem, triancinolona e 6 mL de Hylan G-F20 (G3). A escala visual analógica (EVA), amplitude de movimento (ADM), questionários Womac e Lequesne foram obtidos no início, um, três, seis e doze meses após a injeção. RESULTADOS: Todos os grupos apresentaram melhora clinicamente relevante (> 20%) entre o início e o primeiro mês, mantendo resultados subjetivos durante o estudo (p <0,001). Não foram encontradas diferenças entre os grupos nas avaliações subjetivas (p > 0,05). A flexão aumentou no G2 e G3 até um ano (p = 0,028). A rotação externa melhorou nos grupos Hylan no primeiro mês, mantendo os resultados até um ano (G1, p = 0,041; G2, p = 0,007), enquanto G0 nunca melhorou (p = 0,336). CONCLUSÃO: Lavagem do quadril e injeção de triancinolona, com ou sem Hylan, melhoram a dor, função e qualidade de vida até um ano na OAQ. Hylan pode melhorar a ADM até um ano. Nível de evidência IB, Ensaio clínico randomizado.

ABSTRACT

OBJECTIVE: To evaluate the effects of a multi-professional educational program in patients with knee osteoarthritis (KOA) . METHODS: Prospective randomized controlled trial with 195 KOA patients. One group was submitted to two-day lectures and received educational material about KOA (Class group), and the control group received the educational material only. Patients were evaluated at baseline, twelve and 24 months. At evaluation, patients answered pain and functional questionnaires (WOMAC, Lequesne, VAS and SF-36); reported the intensity of exercise per week; measured the body fat percentage, weight and height to estimate body mass index (BMI); and performed Timed Up & Go (TUG) and Five-Times-Sit-to-Stand (FTSST) tests . RESULTS: The groups presented similar results in all time points with respect to pain (VAS and WOMAC pain), WOMAC, BMI and body fat percentage (p>0.05). The Class group exhibited improved function according to the Lequesne questionnaire, whereas the control group worsened (p=0.02) during follow-up (p<0.02). TUG (p=0.01) and FTSST (p<0.001) improved in the Class group. A higher percentage of patients in the Class group performed regular physical activity (p=0.045) . CONCLUSIONS: The educational program with classes improved the consistency of physical activity and the subjective and objective function of patients with KOA. Level of evidence IA, Prospective Randomized Controlled Trial.


OBJETIVO: Avaliar o efeito de um programa educacional multiprofissional para pacientes com gonartrite. MÉTODOS: Trata-se de um estudo prospectivo randomizado com 195 pacientes portadores de gonartrite. Um grupo recebeu material didático sobre osteoartrite (grupo Controle) e o outro grupo participou de dois dias de aulas práticas e teóricas sobre osteoartrite e também recebeu o material didático (grupo Aula). Os pacientes preencheram questionários para avaliar dor, função e qualidade de vida (WOMAC, Lequesne, EVA, SF-36) no momento da inclusão, e após 12 e 24 meses de seguimento. Nestes mesmos períodos, os pacientes tiveram calculados a percentagem de gordura e o índice de massa corpórea (IMC); realizaram os testes de senta e levanta (TSL) e "Timed-Up-and-Go" (TUG), além de responder perguntas sobre a intensidade da atividade física semanal realizada. RESULTADOS: Os dois grupos não diferiram quanto aos resultados de dor, função (WOMAC), IMC e porcentagem de gordura corpórea (p>0,05). O grupo Aula melhorou e o Controle piorou a função pelo Lequesne (p=0,02) ao longo do tempo (p<0,02). O TUG (p=0,01) e o TSL (p<0,001) melhoraram principalmente no grupo Aula. Uma porcentagem maior de pacientes do grupo Aula aderiu à atividade física regular (p=0,045) . CONCLUSÃO: O programa educacional com aulas melhora adesão à atividade física e a função subjetiva e objetiva dos pacientes com gonartrite. Nível de Evidência IA, Estudo Prospectivo Controlado e Randomizado.

ABSTRACT

INTRODUCTION: Knee osteoarthritis (KOA) is the most prevalent form of osteoarthritis. Low socioeconomic level, age, and obesity are directly correlated with the incidence of the disease. Education, exercise, and diet are the core recommendations of all KOA treatment guidelines. OBJECTIVE: To evaluate the impact of a multiprofessional educational program on patients with KOA. METHODS: Of a total of 198 participants, 150 patients with KOA attended 2 days of lectures (at 1- to 3-month intervals) and received educational material on osteoarthritis, and a control group (48 patients) received educational materials only. Body mass index (BMI), frequency, and intensity of physical activity, pain, function, and quality-of-life scores were assessed at baseline and at 4 and 12 months after the educational program. Bimonthly telephone calls were made to half of the participants. Correlations between BMI, level of education, coping skills, functional, and pain results was procured. RESULTS: The groups were similar in terms of race, gender, affected side, and osteoarthritis severity. The results were not affected by the telephone calls or the patients' level of education. At baseline, 25 performed physical activity, whereas 123 performed at 1 year. Seventy-two (36.36%) patients decreased BMI (45 by 1 point and 27 by more than 2 points). There were some weak correlations such as BMI reduction with pain and functional improvements and with coping results. Significant improvements in function and quality of life were found at 4 months. Quality of life remained improved at 1 year. CONCLUSION: The effect of this educational program in function and quality of life of patients with KOA is very subtle. Interval between classes (1, 2, or 3 months) is not an important issue.

ABSTRACT

OBJECTIVE: To evaluate the relationship between BMI and pain and function in patients with OA undergoing medical treatment following OARSI recommendations. METHODS: Thirty-eight patients were classified according to their arthritis degree by X-ray and body mass index (BMI). All patients completed the WOMAC, Lequesne, and visual analogue pain scale (VAS) questionnaires at baseline and after six months treatment. All patients were treated with diacerhein and analgesics (according to pain), orthotics (when indicated), and an educational program on osteoarthritis. They were instructed on balanced diet and exercise at least three times a week. RESULTS: There was no significant BMI variation in this study. The higher the initial BMI, the lower the improvement in pain (p = 0.03). Pain did not improve significantly (p = 0.2). Function improved (p <0.001) in inverse ratio to the initial BMI. CONCLUSION: BMI determines how patients will improve pain and function.

ABSTRACT

OBJECTIVE: To assess if the initial results of viscosupplementation are improved by the addition of corticosteroid. DESIGN: We evaluated 104 patients receiving usual care for knee osteoarthritis at the Universidade de São Paulo Medical Center. Patients were randomized to receive either a single intra-articular injection of 6 mL of Hylan GF-20 (Group 1) or a single intra-articular injection of 6 mL of Hylan GF-20 plus 1 mL (20 mg) of Triamcinolone Hexacetonide (Group 2). VAS, WOMAC and Lequesne questionnaires were applied at weeks zero (prior the injection), and after one, four, and 12 weeks. RESULTS: The baseline measurements of the two groups with 52 patients each were not statistically different. At week one, WOMAC and VAS showed significantly better results for Group 2 compared to Group 1 (p < 0,05). At week four the scores did not show a statistically significant differences. The groups showed similar results at week 12. CONCLUSION: The addition of Triamcinolone Hexacetonide improves the short term symptom/functional scores of viscosupplementation. .

ABSTRACT

A osteoartrite (OA), forma mais comum de doença articular, afeta principalmente quadris, joelhos, mãos e pés, levando a grande incapacidade e perda de qualidade de vida, sobretudo na população idosa. A importância desta doença cresce a cada ano, na medida em que observamos uma tendência de envelhecimento da população brasileira, com grande aumento da população idosa em relação aos mais jovens. O progressivo entendimento da fisiopatologia da OA, a percepção de que o processo não é puramente mecânico e/ou de envelhecimento, e o esclarecimento das vias inflamatórias envolvidas levaram, recentemente, à aplicação clínica de vários outros medicamentos e medidas. Esta atualização tem como objetivo expor os mais recentes conceitos sobre a fisiopatologia e tratamento da OA.


Osteoarthritis (OA), the most common form of joint disease, affects mainly the hips, knees, hands and feet, leading to severe disability and loss of quality of life, particularly in the elderly population. Its importance grows every year with the aging of the population, with a large increase in the elderly population compared to younger patients. The progressive understanding of the pathophysiology of OA, the perception that the process is not purely mechanical and/or aging, and clarification of the inflammatory pathways involved led recently to the clinical application of various drugs and other measures. This update aims to expose the current concepts on the pathophysiology and treatment of OA.

ABSTRACT

Objetivo: Avaliar se a viscossuplementação com ácido hialurônico em pacientes com artropatia hemofílica grave associada com triancinolona após a lavagem articular com soro fisiológico melhora a dor, a rigidez, a função e a qualidade de vida. Métodos: Onze pacientes com artrite hemofílica de joelhos com e sem acometimento de outras articulações (tornozelos e cotovelos) foram submetidos a lavagem articular com soro fisiológico e subsequente infiltração de hilano e triancinolona em todas as articulações acometidas. Responderam os questionários algo-funcionais (WOMAC e Lequesne), escala analógica visual para dor (VAS) e SF-36, no pré-operatório, e com um e três meses de pós-operatório. Resultados: A dor (VAS e WOMAC dor) e a rigidez (WOMAC rigidez) não apresentaram melhora significativa (p=0,3; p=0,2; p=0,1, respectivamente). Porém a função apresentou uma melhora significativa dada pelo WOMAC função e total (11 pontos em média, p=0,04 e p=0,001, respectivamente). A pontuação no questionário de Lequesne não variou significativamente (p=0,1). Porém tantos os componentes mental como físico do SF 36 tiveram melhoras clinicamente relevantes e significativas (p=0,002). Conclusão: A lavagem articular com soro fisiológico seguida pela infiltração de corticosteroide e hilano é efetiva no tratamento da artropatia hemofílica, sobretudo na melhora funcional e na qualidade de vida. Nível de Evidência IV, Série de casos.


Objective: To assess whether viscosupplementation with hyaluronic acid in patients with severe hemophilic arthropathy associated with triamcinolone after washing with saline improves joint pain, stiffness, function and quality of life. Methods: Eleven patients with hemophilic arthritis of the knee with and without involvement of other joints (elbows and ankles) underwent joint lavage with saline and subsequent injection of Hylan and triamcinolone in all affected joints. The patients answered the algo-functional (Lequesne and WOMAC), visual analog scale for pain (VAS) and SF-36 (quality of life) questionnaires preoperatively, and at one and three months postoperatively. Results: Pain (VAS and WOMAC pain) and stiffness (WOMAC stiffness) did not show significant improvement (p = 0.3, p = 0.2, p = 0.1, respectively). However function had significant improvement given by WOMAC total and function (averaging 11 points, p = 0.04 and p = 0.001). There was no significant variation in scores in Lequesne’s questionnaire (p = 0.1), yet both mental and physical components of SF-36 presented clinically relevant and significant improvements (p = 0.002). Conclusion: Joint lavage with saline followed by injection of corticosteroids and Hylan is effective in the treatment of hemophilic arthropathy, especially in functional improvement and quality of life. Level ofEvidence IV, Case series.

ABSTRACT

OBJETIVO: comparar a rigidez de três diferentes montagens de placa em ponte com a da haste intramedular bloqueada, em tíbias de cadáveres com fratura tipo C. MATERIAIS E MÉTODOS: vinte tíbias humanas captadas de cadáveres, submetidas à fratura do tipo C; quinze fixadas com placas em ponte, divididas em 03 grupos, de acordo com o tamanho das placas (10, 14 e 18 furos) e 05 fixadas com hastes intramedulares bloqueadas. Todas as tíbias foram expostas a cargas progressivas e semelhantes. Foram medidos os deslocamentos de ambos fragmentos (proximal e distal), nos planos sagital, coronal e axial do espaço, conforme incremento gradual de carga. RESULTADOS: tíbias fixadas com placas em ponte de 18 furos apresentam um comportamento biomecânico semelhante às fixadas com haste intramedular bloqueada. CONCLUSÕES: Em fraturas do tipo C em tíbias há maior mobilidade do segmento ósseo distal no plano coronal, quando a fratura é fixada com placas em ponte de 14 e 18 furos que quando fixada com haste intramedular bloqueada sem fresagem. Apesar dessa maior mobilidade, os movimentos relativos entre os fragmentos fraturários nos GHB e GP18 tendem a ser semelhantes entre si.


OBJECTIVE: To compare the stiffness of three different assemblies of bridging plates with intramedullary locking nails in cadaveric models of tibial fractures type C. MATERIALS AND METHODS: Twenty cadaveric tibias subjected to type C fractures; fifteen were fixed with the bridging plate technique and divided into three groups, according to the plate size (10, 14 and 18 holes), and five were fixed with intramedullary nail. All the tibias were exposed to similar and progressive loads. Dislocation of both fragments (proximal and distal) was measured on three planes (sagittal, coronal and axial), as the load was increased. RESULTS: tibias fixed with the 18 hole bridging plate have the same biomechanical behavior of tibias fixed with intramedullary locking nails. CONCLUSIONS: In type C tibial fractures, there is more mobility at the distal segment on the coronal plane when the fracture is fixed with 14 and 18 holes bridging plates as compared to fractures fixed with non-reamed intramedullary locking nails. Even with this mobility, the relative movements between the fragments at GHB and GP18 seem to be similar.

ABSTRACT

As fraturas da patela são prevalentes na faixa etária de 20 a 50 anos e representam 1 por cento das fraturas. São classificadas através de 2 aspectos principais: característica do traço de fratura e presença de exposição óssea, o que dirige a escolha do tratamento dentro das diversas técnicas propostas. Este trabalho objetivou estudar a incidência dos padrões de fraturas patelares e analisar os resultados funcionais encontrados com as diferentes modalidades de tratamento no IOT-HC-FMUSP. Levantou-se 103 prontuários de pacientes com fratura de patela tratados no IOT no período de 1988 - 1999 com seguimento mínimo de 5 anos. A média etária foi de 39,4 anos, 68 por cento do sexo masculino, 51,5 por cento de acometimento do lado direito e 2,9 por cento de bilateralidade. Prevaleceram fraturas transversas (36 por cento); 30 por cento de exposição óssea; técnicas mais utilizadas patelectomia parcial (46,6 por cento), banda de tensão (20,4 por cento), imobilização gessada (17,5 por cento), cerclagem (4,8 por cento) e patelectomia total (2,9 por cento); notou-se 57,1 por cento de excelentes e bons resultados com banda de tensão AO e 44,4 por cento nas patelectomias parciais. Concluiu-se que o resultado funcional final do tratamento da fratura de patela é multifatorial; o tipo de fratura, o modo de tratamento - conservador ou cirúrgico, a idade e o mecanismo de trauma não influenciam, isoladamente, o sucesso da terapêutica.
