英国学者Patil S于2010年6月的《Acta Orthop Belg.》杂志上撰文，报道了他们的一个前瞻对照研究：青少年特发性膝前痛。

  　特发性膝前痛是青少年常见的膝关节疾病。本研究的目的是比较青少年膝前痛组和青少年非膝前痛组的一些参数，如：腘绳肌的紧张程度、髋关节膝关节的运动和关节松弛度。本研究表明：青少年膝前痛是一种自限性疾病，这和腘绳肌的紧张程度有关。

Abstract
Idiopathic anterior knee pain is a common condition in adolescents. The aim of this study was to compare the biometric parameters such as hamstring tightness, hip and knee movements and joint laxity in patients with idiopathic anterior knee pain with a control population of similar age and gender. Patients (n = 34) and controls (n = 34) (age and sex matched) between the age of 11 and 25 were recruited for the study. The mean follow-up of the patient group was 20 months. The patients showed a statistically significant improvement in their symptoms (SF-36 physical component, p = 0.001) despite the fact that half of them did not attend physiotherapy sessions. Patients had statistically significant hamstring tightness (p = 0.04) and increased external hip rotation (p = 0.001) as compared to the control group. These findings support the theory of idiopathic anterior knee pain being a self-limiting condition that is associated with hamstring tightness.
