Hindlimb condemnations occurred in 0-11 per cent (194/173,580) of all cattle at a large Scottish slaughterhouse over a 22-month period. Cows and bulls were more frequently involved than steers or heifers. Gross pathology, studied in 42 cattle (21 per cent of the total condemned), revealed osteoarthritis of the stifle and hip respectively in 19 and 16 cases. The traumatic lesions included meniscal damage, anterior and other ligamentous rupture. The UK loss from such condemnation is estimated at over pounds200,000 in January 1977.
在22个月的时间里，苏格兰一家大型屠宰场中，所有牛的后肢被判不合格的比例为0%至11%（194/173,580）。母牛和公牛比阉牛或小母牛更常出现这种情况。对42头牛（占被判不合格总数的21%）进行的大体病理学研究显示，分别有19例和16例出现了膝关节和髋关节骨关节炎。创伤性损伤包括半月板损伤、前韧带和其他韧带断裂。据估计，1977年1月英国因这种被判不合格造成的损失超过20万英镑。
