Background: Joint cooling devices allow cooling and compression at the same time and thereby increase the efficiency of cooling. Purpose of this research was to identify the effects of knee cooling device on knee anterior laxity. Methods: Ten healthy male young subjects were included in the experiment. Protocol consisted of three 30- minute conditions: cold and compression, compression and sensation of cold. The sequences were random with 24- hour intervals apart. We measured tympanic temperature (Tt), average skin (Ts), and knee skin (Tk) temperature. Knee anterior laxity was measured before and after each condition with the Rolimeter. Results: Tt remained stable, while Ts significantly increased during sensation of cold. Despite the significant temperature change of Tk during first and second conditions, there was no significant difference in knee anterior laxity within and between conditions. Conclusions: 30-minute knee cooling device application with temperature range from 5 o C to 24 o C has no significant effects on knee anterior laxity.
