A stochastic analogue of the deterministic problem of the destruction of the human musculoskeletal system is proposed. Using the generalized Focker-Planck- Kolmogorov equation, calculations of average values were produced, which coincide with solutions of deterministic equations about the thermomechanical reaction of the system of the joint - synovial fluid on periodic and impulse effects. According to the universal dispersion formula, calculations were made for short-term pulsed shock mechanical effects, which are the most devastating for the joint.
