Two hundred ten adults, 100 women and 110 men, were recruited on the condition of always having asymptomatic knee joints. These recruits were initially solicited by newspaper advertisement. The women were recruited in 3 weeks, but additional efforts and 3 months were necessary to assemble the group of men. The volunteers underwent a uniform comprehensive medical history questionnaire, physical examination, and plain film radiographs. The data collected were subjected to computerization and statistical analysis. Although these subjects were always asymptomatic, only 4.5% of 200 women's knees and 21% of 220 men's knees had no "positive" physical findings. The findings of hypermobile patella, patellar crepitus, and lateral patellar position on Merchant x-ray view were common. Findings not present or infrequent in these asymptomatic subjects and potentially pathological were patellar J-sign, decreased range of motion, asymmetrical ligamentous laxity, McMurray's sign, compartmental crepitus, and severe degenerative arthritis or loose bodies on radiograph. The findings in women were different from those observed in men. This gender-specific information should be helpful in patient management but also useful and timely for establishing practice guidelines, treatment algorithms, and outcome study instruments.
210名成年人，其中100名女性和110名男性，在膝关节始终无症状的条件下被招募。这些受试者最初是通过报纸广告招募的。女性在3周内招募完成，但招募男性组则需要额外的努力并耗时3个月。志愿者们接受了统一的综合病史问卷、体格检查和X线平片检查。收集到的数据进行了计算机化处理和统计分析。尽管这些受试者始终无症状，但在200个女性膝关节中，只有4.5%以及在220个男性膝关节中只有21%没有“阳性”体格检查结果。髌骨活动过度、髌股摩擦音以及Merchant位X线片上髌骨外侧位置等表现很常见。在这些无症状受试者中不存在或很少见且可能具有病理学意义的表现包括髌J征、活动范围减小、韧带不对称松弛、麦克马瑞征、关节间摩擦音以及X线片上的严重退行性关节炎或游离体。女性的检查结果与男性不同。这种性别特异性信息不仅有助于患者管理，而且对于制定实践指南、治疗方案和疗效研究工具也很有用且及时。
