During the period of 1976 to 1981, a total of 412 young athletes contacted the Turku Sports Medical Research Unit's (TSMRU) Outpatient Sports Clinic with 586 complaints. These records included 68 athletes with Osgood-Schlatter's disease (OSD), who were initially prescribed an average of 2 months' rest from any physical activity causing pain. Symptoms of tibial tuberosity pain occurred first at the average age of 13.1 years. According to the retrospective questionnaire, the pain caused complete cessation of training for an average of 3.2 months, and the disease interfered with fully effective training for an average of 7.3 months. According to a retrospective questionnaire given to 389 students (191 girls and 198 boys), 50 (12.9%) had suffered from OSD. Nearly one-half of the students, 193 (49.6%), had been active in sports at the age of 13, and 41 (21.2%) of them had suffered from OSD. In those students who were not active in sports, the incidence was only nine (4.5%; P less than 0.001). The incidence (32%) was higher in the siblings of the OSD patients of TSMRU who were active in sports than in the corresponding student group (21.2%). In a group of 22 patients from the TSMRU who had suffered from Sever's disease (calcaneal apophysitis), the incidence of OSD (68%) was significantly higher than in students who were active in sports (P less than 0.001).
1976年至1981年期间，共有412名年轻运动员因586项诉求前往图尔库运动医学研究单位（TSMRU）的门诊运动诊所就诊。这些记录包括68名患有奥斯古德-施拉特病（OSD）的运动员，他们最初被要求平均休息2个月，避免任何会引起疼痛的体育活动。胫骨结节疼痛症状首次出现的平均年龄为13.1岁。根据回顾性调查问卷，疼痛导致训练完全停止的平均时长为3.2个月，该疾病干扰有效训练的平均时长为7.3个月。在对389名学生（191名女生和198名男生）进行的回顾性调查问卷中，50人（12.9%）曾患过OSD。近一半的学生，即193人（49.6%）在13岁时就积极参加体育运动，其中41人（21.2%）曾患过OSD。在那些不积极参加体育运动的学生中，发病率仅为9人（4.5%；P<0.001）。TSMRU中OSD患者且积极参加体育运动的兄弟姐妹的发病率（32%）高于相应的学生群体（21.2%）。在TSMRU的一组22名患有Sever病（跟骨骨骺炎）的患者中，OSD的发病率（68%）显著高于积极参加体育运动的学生（P<0.001）。
