PL Objętość wody zawartej wewnątrz włókien kolagenu jest kluczowym parametrem związanym z pojęciami struktury i funkcji tkanki łącznej. Ponieważ w istniejących teoriach odkształceń skończonych tkanek chrząstkowych nie przeprowadza się rozróżnienia pomiędzy wodą zawartą wewnątrz włókien kolagenu i poza [...]
EN The volume of the intrafibrillar water space -- i.e. the water contained inside the collagen fibers -- is a key parameter that is relevant to concepts of connective tissue structure and function. Because existing theories of finite deformation of cartilaginous tissues do not distinguish between intr[...]

EN The aim of the paper is to propose a novel approach to modelling the macroscopic electromechanical behaviour of cartilage within the framework of linear response. The cartilage is treated as multiphase material with four constituents: anions, cations, viscous fluid and piezoelectric skeleton. The ma[...]

EN Electrospinning is a simple and universal way to produce fibres from a variety of materials having diameters ranging from submicrometers to nanometers. Such fibres can be formed from resorbable and non-resorbable polymers, ceramics and their different combinations containing nanoparticles. Such a me[...]

EN The work presents in vitro and in vivo experiments related to the evaluation of the biological properties of the two groups of carbon fibrous (micro, nano) materials. We investigated the carbon materials in the form of a biomimetic scaffolds made from carbon nanotubes and a composite membrane made f[...]

EN Two scaffolding materials for cartilage regeneration were produced from poly(L-lactide-co-glycolide) (PLG) and PLG modified with sodium hyaluronate (PLG-Hyal). The scaffolds were characterized in terms of their microstructure and surface chemistry. Biological properties of the scaffolds were also ev[...]

EN The paper presents the results of a preliminary study on the structural analysis of the hip joint, taking into account changes in the mechanical properties of the articular cartilage of the joint. Studies have been made due to the need to determine the tension distribution occurring in the cartilage[...]

EN Development of the skeleton is a complex mechanobiological process. Shape and size of the majority of bone elements are the result of endochondral growth and ossification occurring during childhood and adolescent period. The influence of mechanical loading acting in the skeletal system on bone devel[...]

EN This paper is devoted to modelling and investigation of the effects of mechanical loading, blood vessels development and tissue microstructure in osteoarthritis (OA) – a degenerative joint disease. OA is one of the most common diseases affecting the population, and therefore it is a social and medic[...]

EN The paper presents some details about difficulties in modelling of articular cartilage. The most useful method to simulate a mechanism of tissue deformation during load is Finite Element Method (FEM). In this paper the authors present an approach of modelling a damping phenomenon in articular cartil[...]

PL Praca prezentuje nową metodę leczenia rozległych ubytków chrzęstnych z użyciem włókna węglowego. Od grudnia 1993 do listopada 1994 operowaliśmy 4 chorych, u których ubytek chrząstki stawowej wypełniliśmy włókniną węglową. Wczesne 24-miesięczne wyniki są zachęcające, choć muszą być potwierdzone w wie[...]
EN We present a new method of treatment of cartilage defects with the use of carbon fibres. We treated 4 patients with the method from Dec. 1993 to Nov. 1994. Early 24-month follow-ups are good but they must be confirmed in a long-term observation.

PL Ważnym problemem związanym z uszkodzeniami chrząstki stawowej jest jej rekonstrukcja. W pracy dokonano analizy problemów związanych z chrząstką stawową, jej budową, właściwościami oraz metodami rekonstrukcji. W pracy zostaną omówione materiały wykorzystywane w inżynierii tkankowej jako rusztowania d[...]
EN The most important problems to injured articular cartilage is the tissue reconstruction. Detailed analysis of problem associated with articular cartilage, its structure, properties and methods of reconstruction were reviewed in this work. Specifically, different materials used in tissue engineering [...]

EN Growth plate, named also as physis, is the anatomical structure responsible for the bone growth. Apart from numerous biological and biochemical factors, biomechanics has also strong influence on its functioning. Loadings acting on the bone element during its development can change (increase or decre[...]
