Analysis of carrying capacity of synovial unsymmetrical fluid flow in deformed, human joint gap, especially in hip joint, is presented. The following assumptions are taken into account: stationary, isothermal and incompressible synovial unsymmetrical fluid flow in time-dependent magnetic field rotation motion of bone head, squeeze of synovial fluid in human joint gap, changeable synovial non-Newtonian fluid viscosity, changeable and deformed gap height in human joint, and constant synovial fluid density. The simplified system of basic equations for pressure and synovial velocity distribution are analysed. Numerical and analytical formulae for capacity force taking into account conjugation fields of the stresses and deformations occurring in elastic cartilage and in synovial fluid obtained by virtue of theory of elasticity and fluid mechanics can be considered as the novely of this paper. Analytical solutions for he values of capacity forces allow easy numerical calculations, which may be very useful for medical diagnosis.
