The analysis of 1140 observations of ligamento-periostosis of the apex of the patella (the proximal attachment of its proper ligament) revealed that it was rather frequently present (3.1%) in the latent form during the prophylactic examinations of sportsmen, which constituted an important part (7.6%) in the structure of the diseases of the locomotor system. It was confirmed that the disease depended on the intensity of the loads and on the age of the patients. Early (at the preclinical stage) treatment allows to reduce the transition of the latent course of the disease into its clinical forms down to 6%. The administration of a complex treatment with novocaine electrophoresis and vitamin R12, drug blocks of the pathologic foci at the site of the attachment of the ligament and differential correction of the static and dynamic loads provide for steady healing without recurrences and relapses of the disease in 89% of the patients.
