髌股关节疼痛综合征（PFPS）患者的外侧结构较紧。有人提出，通过外侧支持带附着到髌骨的紧密髂胫束（ITB）可能会导致髌骨外侧追踪、髌骨倾斜和压缩。将12名患有PFPS的受试者与12名匹配的对照受试者进行了比较。使用Ober试验测量每例受试者的髋关节内收，作为ITB长度的所有间接测量值。对照组中左腿和右腿髋关节内收的平均值分别为21.4（+/- 4.9）和20.3（+/- 3.8）度，PFPS组中无疼痛腿和疼痛腿分别为17.3（+/- 6.1）和14.9（+/- 4.2）度。单因素方差分析（ANOVA）显示组间差异非常显著（F=4.485，p=0.008），事后分析显示PFPS组与对照组左右腿之间的疼痛差异显著。p=0.002和0.009。本研究的结果表明，患有PFPS的受试者的ITB确实更紧。未来的工作应前瞻性地研究这一观察结果，以确定ITB紧缩是否是PFPS的原因或影响。(C)2008爱思唯尔有限公司保留所有权利。
Tight lateral structures have been implicated in subjects presenting with patellofemoral pain syndrome (PFPS). It has been proposed that a tight iliotibial band (ITB) through its attachment of the lateral retinaculum into the patella could cause lateral patella tracking, patella tilt and compression.Twelve Subjects presenting with PFPS were compared with 12 matched control Subjects. Hip adduction was measured using the Ober test in each subject as ail indirect measure of ITB length. The mean values for hip adduction in the control group were 21.4 (+/- 4.9) and 20.3 (+/- 3.8) degrees in the left and right legs, respectively, and in the PFPS group, 17.3 (+/- 6.1) and 14.9 (+/- 4.2) degrees in the non-painful leg and painful leg, respectively. One way analysis of variance (ANOVA) revealed a highly significant difference between groups (F=4.485, p=0.008) and post-hoc analysis showed a significant difference between the painful leg ill the PFPS group and the left and right legs in the control group., p=0.002 and 0.009, respectively.The results from this study show that subjects presenting with PFPS do have a tighter ITB. Future work should investigate this observation prospectively in order to determine whether a tight ITB is the cause or effect of PFPS. (C) 2008 Elsevier Ltd. All rights reserved.
