In an evaluation of the effect of kneeling work on the knees, 168 actively working carpet and floor layers and 146 house painters were examined with the aid of a questionnaire, a clinical examination, and radiography. Reported knee pain, knee accidents, and treatment regimens for the knees were more common among the carpet and floor layers than among the painters. Radiographic changes of the tibiofemoral joint were noted equally in the two occupational groups, but osteophytes of the patella were more common among the carpet and floor layers than among the painters. In a multivariate analysis, the determinants of osteophytosis of the knee were age, occupation, knee accidents, and smoking, and osteophytosis may be due to more frequent workbreaks from kneeling postures among smoking workers. This study indicates that kneeling work increases the risk of knee disorders and such radiographic changes that might be an initial sign of knee degeneration.
在一项关于跪姿工作对膝盖影响的评估中，借助问卷调查、临床检查和X光摄影对168名在职地毯和地板铺设工以及146名房屋油漆工进行了检查。报告显示，地毯和地板铺设工的膝盖疼痛、膝盖意外受伤及膝盖治疗方案比油漆工更为常见。两个职业组胫股关节的X光变化情况相同，但地毯和地板铺设工髌骨的骨赘比油漆工更为常见。多变量分析显示，膝盖骨赘形成的决定因素为年龄、职业、膝盖意外受伤和吸烟，而骨赘形成可能是由于吸烟工人跪姿工作时更频繁地休息。这项研究表明，跪姿工作会增加膝盖疾病的风险以及此类X光变化，而这些变化可能是膝盖退化的初始迹象。
