Sports injuries have become one of the most common injuries in modern Western societies, and numerous sources point out that volleyball (along with football and basketball) ranks first in the number of injuries in ball sports. In general, a sports injury refers to any condition that prevents athletes from fully participating in normal training or competition. This definition is most often used in various studies that study incidence/prevalence (number of injuries per player per 1000 volleyball hours played) and injury rate. The aim of this work was to determine the incidence and localization of knee pain and injuries in a sample of 73 volleyball players who compete in the highest level of the Croatian competition, in the Superliga, using the Questionnaire for assessing the incidence of knee pain and injuries developed by Penga, Milić and Milavić (2020). The measured occurrence of pain in volleyball players most often occurs after sports activity and during sports activity, and the lowest average values have the variables related to the occurrence of pain when sliding on the surface and the occurrence of pain that causes the interruption of sports activity. According to the results, injuries in most cases occur on the front of the knee, below the patella. In second place in terms of frequency are injuries on the front side, above the patella and on the front side of the patella. The obtained results correspond to the previous findings. The limitation of this work is reflected in the small sample, but it is about elite Croatian volleyball players who compete in the highest level of the Croatian league. Future research and guidelines point to further research, by increasing the number of respondents and determining differences with regard to chronological age and playing role.
