Realistic simulations joint replacement human joint
Franta, L. ; Pražák, Josef
Any artificial testing of joint replacement is considered as contribution significant to research in the field of joint replacements. The fundamental parameter, which influeces a length of survival, is an effective coefficient of friction, especially in low mutual speed of friction surfaces of joint replacements.

Frictional heating of total joint replacements
Němeček, R. ; Pražák, Josef
Total joint replacements heat up due to friction more then natural joints. The paper contains review of frictional heating of total joint replacements in vitro and in vivo. Thermal effects during friciton of femoral (vitalium) and tibial (UHMWPE) components of the knee joint replacement with the physiological solution, HA, bovine serum lubrication depending on the load, frequence and damage of UHMWPE are studied.

Thermal aspects of friction in joint replacements
Němeček, R. ; Pražák, Josef
Thermal effects during friction of femoral (vitalium) and tibial (UHMWPE) components of the knee joint replacement with the physiological solution, HA, bovine serum lubrication depending on the load, frequence and damage of UHMWPE are studied. There is the possibility of monitoring the state of joint replacements in vivo.
