This is the most complex joint in the human body. Accordingly, its recovery is a most difficult process. The sport practitioner should immediately tune in to long systemic work. For proper recovery of the knee, it is necessary to strengthen not only the joint itself, but also all nearby muscles, and get rid of excess weight. Constant monitoring on behalf of the coach, updating of the programme and loads are required. According to professional standards, it is necessary to restore the joint on a natural grass cover. Problems with the knee joint are often manifested in adolescents
who enter the phase of rapid growth. These are Schlatter-Osgood disease, Koenig diseases, and chondromalacia. However, contrary to the ancient myths that what is not remedied needs to be “outgrown”, everything is redressible with timely treatment.
