Injuries are an integral part of every sport. We define a sports injury as an injury that occurs while engaging in a sports activity. There are various reasons for injury. As a kind of first reason, the disproportion between physical effort and the body's readiness for said effort is considered. The aim of this research was to determine the incidence and localization of knee pain in a sample of 53 female futsal players who compete in the highest level of the Croatian competition, in the 1st HMNLŽ using the Questionnaire for assessing the incidence of knee pain and injury developed by Penga, Milić and Milavić (2020). In addition to the primary goal, the research also tried to determine the time of onset of pain in futsal players, determine the localization of knee pain, and determine the frequency and types of preventive training. All players are of legal age and are between 18 and 30 years old. The average chronological age of female players is 24.7 years. The average body height is 168.5 cm, and the body weight is 64.19 kg. The questionnaire was adapted for futsal and has very good metric characteristics, which helped us to qualitatively measure the occurrence and localization of pain and injuries of futsal players. By considering the mean values in the distribution of the results, we came to the conclusion that one variable significantly deviates from the others. The majority of female futsal players stated that the most common pain occurs after sports activity. The second most common type of pain is pain during sports activities. The lowest average values have the variables related to the occurrence of pain during normal daily activities and the occurrence of pain that causes the interruption of sports activities. According to the results, injuries most often occur on the front of the knee, below the patella. Injuries on the front side, above the patella, ranked second in terms of frequency. The obtained results correspond to the previous findings. The limitation of this work is the small number of respondents.
