25. Cartilage reconstruction using self-anchoring implant with functional gradient
This study presents an innovative and original biomaterial designed to substitute for articular cartilage and mimic its mechanical behavior, including elastic cushioning and the characteristics of fiber-reinforced gel. The material was composed of polyurethane and bioglass microfiber 45S5. It was designed to present a tribological surface to the cartilage of

26. The use of Mycobacterium tuberculosis HspX and GlcB proteins to identify latent tuberculosis in rheumatoid arthritis patients
Rheumatoid arthritis (RA) is an autoimmune disease characterised by the destruction of articular cartilage and bone damage. The chronic treatment of RA patients causes a higher susceptibility to infectious diseases such as tuberculosis (TB); one-third of the world’s population is latently infected (LTBI) with Mycobacterium tuberculosis(Mtb). The tuberculin

27. Arthroscopic study of injuries in articular fractures of distal radius extremity
OBJECTIVE: To analyze the incidence of wrist ligament and cartilage associated fractures of the distal radius, through arthroscopy, correlating with AO/ASIF classification. METHODS: Thirty patients aged between 20 and 50 years old, with closed fracture from groups B and C according to AO/ASIF classification were selected. All of them were submitted to

28. Glucosamine and chondroitin sulfate association increases tibial epiphyseal growth plate proliferation and bone formation in ovariectomized rats
OBJECTIVE: The growth plate consists of organized hyaline cartilage and serves as a scaffold for endochondral ossification, a process that mediates longitudinal bone growth. Based on evidence showing that the oral administration of glucosamine sul

29. Morphometric evaluation of condylar cartilage of growing rats in response to mandibular retractive forces
INTRODUÇÃO: a superfície do côndilo da mandíbula é constituída por quatro camadas: uma externa (constituída de tecido conjuntivo denso), seguida pela camada de células indiferenciadas, cartilagem hialina e osso. Poucos estudos demonstraram o comportamento da cartilagem condilar quando a mandíbula é posicionada posteriormente, como na terapia para

30. Study on nano-structured hydroxyapatite/zirconia stabilized yttria on healing of articular cartilage defect in rabbit
PURPOSE: Articular Cartilage has limited potential for self-repair and tissue engineering approaches attempt to repair articular cartilage by scaffolds. We hypothesized that the combined hydroxyapatite and zirconia stabilized yttria would enhance the quality of cartilage healing. METHODS: In ten New Zealand white rabbits bilateral full-thickness osteochondra

31. Condrogênese a partir de células-tronco do líquido amniótico humano estimulado com TRF-ß3 em micromass / Chondrogenesis differentiation of mesenchymal stem cells from human amniotic fluid with TGF-beta3 in micromass culture system
Introduction: The use of mesenchymal stem cells (MSC) for reconstruction of articular cartilage, leads to a promising therapeutic alternative, due to the tissue vulnerability to injuries and irreversible degenerative process. The aim of this study was to investigate the chondrogenic potential of MSC from human amniotic fluid in Micromass system (high-density

32. Estudo experimental em coelhos do efeito do ácido hialurônico na apoptose pós-traumática de condrócitos / Rabbit experimental-study of hyaluronic acid effect on chondrocyte impact-induced apoptosis
The aim of this study was to assess whether intra-articular injection of high doses of hyaluronic acid immediately after trauma, can reduce apoptosis of chondrocytes. We have developed an experimental study with forty knees of adult rabbits. Animals were anesthetized and each one had had three knee injuries with a block of 1kg, released through a cylinder, 1

33. Efeito do exercício resistido na cartilagem articular de modelo animal de osteoartrite
The aim of this study was to evaluate the effect of a strength exercise protocol on articular cartilage in animal model of osteoarthritis (OA). Thirty-six rats were divided in 6 groups: Control (C, n = 6), Osteoarthritis (OA, n = 6), Sham (S, n = 6), Control with exercise (E n = 6), Osteoarthritis with exercise (OAE, n = 6) and Sham with exercise (SE, n = 6)

34. Investigação das alterações locais e sistêmicas do onset da osteoartrite em joelhos de ratos após a transecção do ligamento cruzado anterior
Objective: To evaluate the chondrocytes apoptosis by caspase 3 expression and its relation with the knee articular cartilage thickness and cellularity, at the acute phase after anterior cruciate ligament (ACL) transection, as the experimental model of osteoarthritis (OA). Material and Methods: Seventy two male Wistars rats were divided into 3 groups: ACL tra

35. Estudo da histoarquitetura do colágeno da cartilagem, ligamentos e sinóvia em modelo experimental de diabetes mellitus / Histoarchitecture study of collagen in cartilage, ligaments, and synovium in experimental diabetes mellitus
Essa pesquisa foi realizada com o objetivo de avaliar os componentes da matriz extracelular da cartilagem, ligamentos, tendão e sinóvia em modelo experimental de diabetes. Metodologia: Ratos Wistar jovens foram divididos em grupo diabético (DG n = 15) induzido por estreptozotocina (STZ, 35 mg / kg) e grupo controle (CG, n = 15). Foram avaliados o peso, a

36. Atualização no diagnóstico e tratamento das lesões condrais do joelho
O tratamento das lesões condrais no joelho ainda permanece um desafio para o cirurgião ortopédico, principalmente pelas próprias características da cartilagem, que promovem um baixo potencial de regeneração. As lesões condrais podem ser causadas por estímulos metabólicos, genéticos, vasculares e traumáticos e são classificadas de acordo com o ta
