Most people associate sports with feelings of satisfaction and fulfilment, but the world of sports also has its other not so beautiful side, namely injuries. This is where kinesiologists play an important role, where through training processes they try to achieve prevention as high-quality, safe and fast as possible for the athlete himself. When we talk about only jumping knee, it is an injury that is associated with sports that require a large number of jumps and changes in the direction of movement, i.e. dynamic movements, and one of these sports is basketball. Jumper's knee is the result of overexertion syndrome, and the very localization of this pain is at the starting point of the patellar ligament. The aim of this paper was to further investigate the issue of jumping knee and draw attention to the health of young basketball players. The aim of this work is to investigate the condition of the jumping knee in young basketball players. In accordance with the objective, a sample of 124 basketball players (n=124) was used.
