研究设计：病例对照研究。目的：比较有和无髌骨股痛（PFP）的成年女性受试者的髌骨活动度。背景：虽然异常的髌骨活动被认为是导致PFP的原因之一，但目前没有公开的证据支持这一观点。在某种程度上，缺乏证据是因为尚未建立可靠的临床测量方法来测量髌骨活动性和确定异常髌骨活动性的客观标准。方法和措施：研究样本由22名患有PFP的女性（PFP组）和22名无膝关节疼痛的女性（对照组）组成，根据年龄、身高和体重指数与PFP受试者相匹配。使用专门设计的仪器客观地测量髌骨活动度。测量髌骨外侧和内侧位移、髌骨活动平衡（外侧减去内侧髌骨位移）、外侧髌骨活动指数（外侧髌骨位移除以髌骨宽度）和内侧髌骨活动指数（内侧髌骨位移除以髌骨宽度）。结果：PFP组和对照组个体间髌骨外侧和内侧活动值无显著差异。当将正常髌骨活动度任意定义为平均活动度+/- 2 SDs时，根据对照组的数据，正常髌骨外侧移位在72 - 176 mm范围内，正常髌骨内侧移位在6.8 - 14.0 mm范围内。外侧和内侧髌骨移位测量的组内相关系数和组间可靠性从0.80到0.97不等。结论：尽管患有和不患有PFP的女性髌骨活动度没有显著差异，但这些测量结果为该组提供了正常髌骨活动度的参考信息。
STUDY DESIGN: Case control study.OBJECTIVE: To compare the patellar mobility of female adult subjects with and without patellofemoral pain (PFP).BACKGROUND: Although abnormal patellar mobility is believed to be one of the causes of PFP there is currently no published evidence to support this contention. In part, this lack of evidence is because a reliable clinical measurement method to measure patellar mobility and objective criteria to define abnormal patellar mobility have not been established.METHODS AND MEASURES: The study sample was comprised of 22 females with PFP (PFP group) and 22 females who had no knee pain (control group), matched by age, height, and body mass index to the subjects with PFP. Patellar mobility was measured objectively using a specially designed apparatus. Measurements of lateral and medial patellar displacement, patellar mobility balance (lateral minus medial patellar displacement), lateral patellar mobility index (lateral patellar displacement divided by patellar width), and medial patellar mobility index (medial patellar displacement divided by patellar width) were used.RESULTS: Lateral and medial patellar mobility values were not significantly different between the individuals in the PFP and control groups. When normal patellar mobility was arbitrarily defined as the average mobility +/- 2 SDs, based on the data from the control group, normal lateral patellar displacement was within a range of 72 to 176 mm and normal medial patellar displacement was within a range of 6.8 to 14.0 mm. The intraclass correlation coefficient for intratester and intertester reliability of lateral and medial patellar displacement measurements varied from 0.80 to 0.97.CONCLUSION: Although there were no significant differences in patellar mobility between females with and without PFP, these measurements give reference information about normal patellar mobility for this group.
