The present study seeks to determine the role of etiology in rehabilitating injured players and the efficiency of return-to-play. The researcher hypothesizes that there are statistically significant differences in the functional efficiency of the ankle joint between injured and non-injured players. Additionally, it is hypothesized that there is a statistically significant relationship between the functional etiology of ankle joint injury and return to play efficiency among tennis players. The research population and sample include tennis players who are registered in the Middle Euphrates sports clubs and who have suffered an injury in the ankle joint, whether during the current sports season or previous seasons. The number of injured players was found to be 70. The researcher randomly selected 30 players to participate in functional tests, 30 players to participate in answering a questionnaire containing questions regarding etiology and their level of interest in this vital issue, and 10 players to participate in a pilot study. The research variables and tests were identified and determined based on scientific research. Pre-tests were conducted on the research groups regarding functional variables, followed by preparing a form regarding etiology. The researcher conducted the main experiment on the research groups for a period not exceeding 8 weeks regarding exercises and an equal period regarding sessions for each group. The post-tests were conducted on the research sample, and the results were analyzed and discussed to reach conclusions and recommendations. The researcher concludes that etiology significantly contributes to enhancing the players' knowledge about injury etiology mechanisms.
