Previous studies that have described the prevalence of patellofemoral pain (PFP) have been limited to samples of military personnel or sporting populations, and convincing data in the general Chinese population are lacking. The present study defined the prevalence of PFP and knee pain in the general population of Chinese young adults and evaluated whether gender, age, or body mass index (BMI) were associated with PFP.
An anonymous online questionnaire survey was open to the general public in China. A self-report questionnaire was used to specifically identify PFP. The population aged 18-40 years was enrolled in the study and completed the questionnaire. The prevalence of PFP and knee pain in the overall sample and in subgroups stratified by sex, age, and BMI was estimated. Logistic regression analysis was conducted to determine if there was a significant association between PFP and sex, age, or BMI.
A total of 1153 participants were enrolled in the study. The prevalence of PFP in the overall sample and among the male and female participants was 20.7, 20.3, and 21.2%, respectively. The prevalence of the knee pain in the overall sample and among the male and female participants was 35.6, 38.2, and 33.7%, respectively. The prevalence of PFP in the subgroups stratified by age and BMI did not differ significantly between the groups. Gender, age, and BMI did not have significant associations with the prevalence of PFP.
PFP is common in the general Chinese population. Clinicians should direct more attention toward the early diagnosis of and interventions for PFP.
以往描述髌股关节疼痛（PFP）患病率的研究仅限于军事人员或体育人群样本，缺乏中国普通人群的确凿数据。本研究确定了中国年轻成年人普通人群中PFP和膝关节疼痛的患病率，并评估性别、年龄或体重指数（BMI）是否与PFP相关。
在中国向公众开展匿名在线问卷调查。使用自我报告问卷专门识别PFP。年龄在18 - 40岁的人群纳入研究并完成问卷。估计总体样本以及按性别、年龄和BMI分层的亚组中PFP和膝关节疼痛的患病率。进行逻辑回归分析以确定PFP与性别、年龄或BMI之间是否存在显著关联。
共1153名参与者纳入研究。总体样本以及男性和女性参与者中PFP的患病率分别为20.7%、20.3%和21.2%。总体样本以及男性和女性参与者中膝关节疼痛的患病率分别为35.6%、38.2%和33.7%。按年龄和BMI分层的亚组中PFP的患病率在各组之间无显著差异。性别、年龄和BMI与PFP的患病率无显著关联。
PFP在中国普通人群中很常见。临床医生应更加关注PFP的早期诊断和干预。
