目的：跳跃者膝关节在所有标准的运动员中引起显著的发病率。然而，很少有参考数据的临床过程中，这种情况下，大量的患者，本研究的目的是纠正这一点。方法，一项回顾性研究的过程中，100名运动员的膝盖提出了运动医学诊所在9年内进行。受试者完成了一份问卷，旨在收集运动参与，症状和运动时间的细节。超声检查结果记录于放射科医师报告。histological结果获得了手术的患者。结果-四十八名受试者回忆说，跳投膝关节的症状开始于20岁之前。症状使33人无法参加体育活动超过6个月，其中18人缺课超过12个月。49名受试者有两次或两次以上单独的症状发作。超音波检查显示在髌骨下极与髌腱深面交界处有一特徴性低回声区。组织学检查显示分离和破坏的胶原纤维偏振光显微镜和增加粘液基质一致的肌腱胶原蛋白的损伤，而没有inflations.Conclusions-Jumper的膝盖有可能是一个衰弱的条件，为运动员。大约33%的运动员在运动医学诊所接受跳跃者膝关节治疗，超过六个月无法恢复运动。
Objectives-Jumper's knee causes significant morbidity in athletes of all standards. However, there are few reference data on the clinical course of this condition in a large number of patients, and the aim of this study was to rectify this.Methods-A retrospective study of the course of jumper's knee in 100 athletes who presented to a sports medicine clinic over a nine year period was carried out. Subjects completed a questionnaire designed to collect details of sport participation, symptoms, and time out of sport. Ultrasonographic results were recorded from the radiologists' reports. Histopathological results were obtained for patients who had surgery.Results-Forty eight subjects recalled that symptoms of jumper's knee began before the age of 20 years. Symptoms prevented 33 from participating in sport for more than six months, and 18 of these were sidelined for more than 12 months. Forty nine of the subjects had two or more separate episodes of symptoms. Ultrasonography showed a characteristic hypoechoic region at the junction of the inferior pole of the patella and the deep surface of the patellar tendon. Histopathological examination showed separation and disruption of collagen fibres on polarisation light microscopy and an increase in mucoid ground substance consistent with damage of tendon collagen without inflammation.Conclusions-Jumper's knee has the potential to be a debilitating condition for a sports person. About 33% of athletes presenting to a sports medicine clinic with jumper's knee were unable to return to sport for more than six months.
