Knee osteoarthritis is a major worldwide public health problem. Mechanical factors generally are considered important in its pathogenesis. Whether floor activities increase the risk of knee osteoarthritis is unclear. We performed a population-based survey to document the association of floor activities with pattern and severity of knee osteoarthritis. We identified 288 women and 288 men 40 years or older from Songkhla province in southern Thailand. We recorded their lifetime histories of four common positions in floor activities: squatting, lotus, side-knee bending, and kneeling. Involvement of osteoarthritis was categorized in three patterns: isolated patellofemoral, isolated tibiofemoral, and combined. We used multinomial logistic regression analysis adjusted for age, gender, body mass index, and smoking status to identify associations between lifetime floor activity and knee osteo-arthritis. Squatting and side-knee bending positions increased the relative risk of radiographic knee osteoarthritis. All types of floor activities except kneeling increased the risk of moderate to severe radiographic knee osteoarthritis. Squatting and lotus positions increased the relative risk of knee pain with radiographic osteoarthritis. Our data suggest habitual lifetime squatting, lotus, and side-knee bending positions increase the risk of knee osteoarthritis.
膝关节骨关节炎是一个全球性的重大公共卫生问题。机械因素通常被认为在其发病机制中很重要。地板活动是否会增加膝关节骨关节炎的风险尚不清楚。我们进行了一项基于人群的调查，以记录地板活动与膝关节骨关节炎的类型和严重程度之间的关联。我们从泰国南部宋卡省确定了288名40岁及以上的女性和288名男性。我们记录了他们在地板活动中四种常见姿势的终生经历：蹲姿、莲花坐、侧膝弯曲和跪姿。骨关节炎的受累情况分为三种类型：孤立性髌股关节型、孤立性胫股关节型和混合型。我们使用多因素逻辑回归分析，并对年龄、性别、体重指数和吸烟状况进行了调整，以确定终生地板活动与膝关节骨关节炎之间的关联。蹲姿和侧膝弯曲姿势增加了膝关节影像学骨关节炎的相对风险。除跪姿外，所有类型的地板活动都增加了膝关节中度至重度影像学骨关节炎的风险。蹲姿和莲花坐姿势增加了影像学骨关节炎伴膝关节疼痛的相对风险。我们的数据表明，终生习惯性的蹲姿、莲花坐和侧膝弯曲姿势会增加膝关节骨关节炎的风险。
