ABSTRACT
BACKGROUND: It is known that implied memory of intraoperative noise influences postoperative pain. The aim of this study was to evaluate the influence of different intraoperative noise protection methods during total knee arthroplasty on postoperative pain scores. MATERIAL AND METHODS: A total of 83 patients were included in this prospectively designed, double-blind trial and underwent total knee arthroplasty with psoas compartment and sciatic nerve regional anesthesia and additionally propofol sedation. After randomization patients were assigned either to the noise protection group, the music group or the control group. Postoperative pain scores (VAS) were evaluated in each group. RESULTS: In the three different time intervals evaluated there were no significant differences between the groups. Also the pain maxima for each postoperative day showed no significant difference but there was a slight trend to the advantage of the music group. CONCLUSION: Even though there were no significant effects of music or noise protection on postoperative pain scores, it can be concluded, as has been done by many other authors that music should be used in the perioperative setting for general patient comfort.

Although Taekwondo is becoming an increasingly popular sport, there is a lack of reliable epidemiologic data on Taekwondo injuries. To perform an epidemiologic study on the variety of types of injury in professional and amateur Taekwondo athletes and to find a relation between Taekwondo style, skill level, weight-class and warm-up routine and the occurrence of injuries, we analysed the injury data using a 7-page questionnaire from a total of 356 Taekwondo athletes who were randomly selected. Overall, we registered a total of 2,164 injuries in 356 athletes. Most traumas were contusions and sprains in the lower extremities. Professional Taekwondo athletes have an increased risk of injury in comparison to recreational athletes. Taekwondo style, weight class and tournament frequency have an influence on the athlete's injury profile. Warm-up routines were found to have a positive effect on injury rates. Overall, Taekwondo may be considered a rather benign activity, if injuries during Taekwondo tournaments can be avoided. If not, Taekwondo can result in serious musculoskeletal problems.
